After suggesting that entertaining is best understood in phenomenological terms (§1) and arguing against the viability of reductive and eliminative accounts of entertaining (§2), this essay develops a nonreductive characterization of entertaining in terms of its connections to a web of neighboring attitudes (§§3–6). §0. I'.#*1-%.$*': U'1"#+.&'1$'2 .(" A..$.-1"+ The functionalist orthodoxy in the philosophy of mind offers two pictures of the propositional attitudes. The dominant picture is of a broad web of causally interrelated attitudes, each of which is understood exhaustively in terms of its causal/functional role in the web. But functionalism also offers a recessive picture that analyzes all propositional attitudes into logical combinations of belief and desire: being glad that p is just believing that p and desiring that p; fearing that p is just believing that !p and desiring that ~p; being disappointed that p is just believing that p and desiring that ~p; hoping that p is believing that !p, believing that !~p, and desiring that p; and so on.1 The connection between these two functionalist pictures is unclear. The dominant functionalist picture faces a problem that has recently come to the fore in several areas of philosophy. If each attitude is the other attitudes' wash, so to speak, it is unclear how we are supposed to grasp the nature of any of them. To understand the nature of attitude A in terms of its connections to B and C, we would have to know what B and C are; if we are told that we can understand the nature of B in terms of its connections to A and D, and C in terms of its connections to A and E, this only postpones understanding of A, B, and C until D and E are understood; eventually the circle closes, but we still have no grasp on any single node in the overall web. Related to this is the problem of possible permutations: in certain webs-ones with the right kind of internal symmetry-certain permutations of nodes are possible that do not perturb the web of connections construed purely relationally. Often there is nonetheless a strong intuition that the intrinsic nature of the permuted nodes is different, even though their relational pro3le is strictly identical. Thus, perhaps belief and desire can be permuted in a way that preserves their functional/relational pro3les.2 After all, there is no a priori guarantee that the cognitive 'half' and the conative 'half' of the web of attitudes are not perfectly symmetrical in a way that would allow such permutations. These sorts of problem have been raised in recent discussions of global descriptivism in the philosophy of language (Lewis 1984), 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 2 / AMERICAN PHILOSOPHICAL QUARTERLY structural realism in the philosophy of science (Demopoulos and Friedman 1985), and dispositional essentialism in the metaphysics of properties and laws (Armstrong 2004, chap. 10). The general form of the worry goes back to Newman's (1928) critique of Russell's (1927) descriptivism. The standard response to this sort of challenge is to recognize that at least some nodes in the web must be understood independently of their connections to other nodes. Their intrinsic nature must be grasped directly through something like immediate acquaintance. This notion of direct or immediate acquaintance is certainly elusive, even mysterious. But something like it appears to be needed. Thankfully, the notion is less mysterious in the mental than in those other domains, since the idea of immediate acquaintance with one's own mental states has struck many as independently compelling.3 The move from the dominant to the recessive functionalist picture can be seen in light of these problems. Given that there is no way to rule out epistemically possible permutations of the web of attitudes, especially if the cognitive and conative 'halves' of the web are perfectly symmetrical, it may be necessary to grasp the nature of the paradigmatic cognitive attitude and conative attitude-belief and desire, say-by direct acquaintance. Once we have an independent handle on belief and desire in this way, we can understand the other attitudes in terms of their connections to belief and desire, as well as to each other. The web no longer 4oats unmoored from any grasp of individual attitudes. If this is how we understand the role belief and desire play in a viable functionalist picture of the attitudes, belief and desire must be eligible objects of acquaintance. They must be something we can encounter directly, without appreciating the whole functional architecture of the mind. Plausibly, the only mental features that can be encountered in this direct way-the mind's only eligible objects of acquaintance-are phenomenal features. It follows that for belief and desire to play the sort of theoretical role outlined here, there must be phenomenal features characteristic of them-a distinctive phenomenology of believing and a distinctive phenomenology of desiring. A promising characterization of these contrasting phenomenologies is painted forth by J. L. Cohen (1992, p. 11): Feeling it true that p may thus be compared with feeling it good that p. All credal feelings, whether weak or strong, share the distinctive feature of constituting some kind of orientation on the 'True or false?' issue in relation to their propositional objects, whereas affective mental feelings, like those of anger or desire, constitute some kind of orientation on the 'Good or bad?' issue.4 Cohen's articulation of 'credal feelings' and 'affective feelings' in terms of a phenomenal orientation on two distinct issues is particularly seductive, but the general idea that there is a cognitive phenomenology of aiming at the true and a conative phenomenology of aiming at the good goes back at least to Brentano (1874, 1889). There is an inviting connection between the phenomenological distinction between orientations on the 'true or false' and 'good or bad' issues, on the one hand, and the more familiar distinction between mind-to-world and world-to-mind directions of 3t, on the other. The latter distinction is standardly appealed to in the functionalist literature, but an assay of what exactly it comes to is harder to 3nd.5 One suggestion may therefore be to elucidate the direction-of-3t distinction in terms of the phenomenal-orientation distinction. It is possible, of course, that a nonphenomenological elucidation of the distinction could be devised. But it is less clear how, construed in terms of a nonphenomenological notion of direction of 3t, belief and desire could be eligible objects of acquaintance. These considerations recommend construing the difference between belief and desire not in strictly functional terms but in phenom1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 enological terms, to do with the difference in phenomenal orientation or direction of 3t. If this is how we think of the difference between belief and desire as two fundamental attitudes, however, we must recognize that there is a third fundamental propositional attitude, which involves neither phenomenal orientation: entertaining. Entertaining a proposition requires an orientation on neither the 'true or false' nor the 'good or bad' issue. It has neither a mind-to-world nor a world-to-mind direction of 3t. That, at least, is the guiding idea of this essay. The plan of the essay is as follows. After arguing, in §2, that entertaining can neither be reductively accounted for in terms of belief and desire (as the reigning belief-desire psychology would require) nor eliminated altogether, the essay attempts to provide a nonreductive characterization of entertaining in terms of its connections to other propositional attitudes: §3 explores connections to a number of closely related notions, such as considering, contemplating, and apprehending; §4 explores connections to a wider circle of notions, including thinking, believing, and judging; §5 explores connections to desire and the emotions; §6 concludes with the general shape of the emerging account of entertaining. §5. T(" I##"1-%$6$)$./ *7 E'."#.&$'$'2 Many mental verbs (e.g., 'thinking') can be used to designate either a mental process or the product of such a process (e.g., either the process of thinking or the ensuing thought). Perhaps because of the peculiar character of entertaining as aiming neither at the true nor at the good-nor at anything else-the distinction is less obvious for 'entertaining.' Here the term episode will be used to denote a unit of mental activity where the process/ product distinction does not apply so clearly. Thus, this essay's concern is with episodes of entertaining. Still, talk of entertaining can be used to refer to a number of different phenomena, including but not restricted to the following: p p p p This essay's concern is with entertaining as a propositional attitude, so it is the second formulation that will be taken as canonical (though also the 3rst as shorthand for the second).6 It is this kind of entertaining that is claimed here to frustrate the functionalist thesis of analyzability into logical combination of belief and desire. One kind of objection to the functionalist project is that some attitudes, although involving belief-desire combinations, are not exhausted by those but also involve an extra sui generis residue. One might argue, in this vein, that being glad the weather is nice involves believing that it is and desiring that it be, but in addition also involves what may be characterized as the proprietary phenomenology of gladness: a certain glad feeling that does not reduce to any feeling the relevant belief and desire might bring along. A completely different, and in some respects more radical, objection is that there exist some propositional attitudes that do not even involve either a belief component or a desire component. Such attitudes may be accompanied by beliefs and/or desires but do not have beliefs and/or desires as components. This is the case, it is contended, with entertaining. Consider an episode of entertaining the proposition that the order and connection of ideas is the same as the order and connection of things (as Spinoza says in Ethics, bk. II). Certainly, entertaining this proposition does not seem to involve any element of desire; entertaining that the order and connection of ideas is the same as the ENTERTAINING AS A PROPOSITIONAL ATTITUDE / 3 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 4 / AMERICAN PHILOSOPHICAL QUARTERLY order and connection of things implies neither wanting it to be, nor wanting it not to be, nor wanting anything else in particular.7 More interestingly, such an episode does not seem to involve any element of belief; one could entertain the proposition precisely because one neither believes nor disbelieves it. Thus, entertaining the proposition involves neither desiring anything nor believing anything. A fortiori, it cannot be reduced to any combination of desiring and/or believing.8 The heart of the problem for the functionalist is that entertaining involves neither mindto-world nor world-to-mind direction of 3t with respect to the proposition entertained. This lack of any '3t' relation to the world captures the doxastic 'neutrality' manifest in entertaining. One can entertain any proposition regardless of one's conception of how the world is or should be, hence regardless of one's conceptions of the true and the good. Accordingly, entertaining does not have any satisfaction conditions that might fail to be met if the world neither is nor ought to be a certain way. Since belief and desire both bear the '3t' relation to the world, a mental state that does not bear it cannot be analyzed in terms of them.9 Thus, entertaining must be treated as irreducible to belief and desire.10 There is one more option for the functionalist committed to the belief-desire thesis (the thesis that all propositional attitudes can be understood in terms of combinations of belief and desire). This is to go eliminativist rather than reductivist with respect to entertaining, that is, deny that such a mental phenomenon exists. According to Mandelbaum (2010), for example, there is no act of mere entertaining separate from believing. As a matter of empirical fact, our belief-formation mechanisms are such that we never entertain any proposition without instantaneously believing it.11 Belief is the default relation to any proposition that comes before the mind. There are many dif3culties with this suggestion, but the 3rst objection to it is that mere entertaining is introspectively manifest. One can simply tell by introspection that one is merely entertaining the proposition that the order and connection of ideas is the same as the order and connection of things; one may be unsure whether they are, not because one's immediate belief that they are has been rescinded in light of evidence acquired more recently, but because one never formed an orientation on the 'true or false?' question to begin with. Mandelbaum's response to this objection from introspection is that beliefs are dispositional states, and dispositional states are not introspectively available, so one cannot tell by introspection that one does not believe that the order and connection of ideas is the same as the order and connection of things. However, regardless of what belief is, in the example above the episode that one is introspecting (whose content is that the order and connection of ideas is the same as the order and connection of things) is certainly not a standing disposition, but an occurrent mental act. So even if it is true that one cannot tell by introspection which dispositional beliefs one does and does not have, the act of entertaining is not one of those. For all Mandelbaum argues, some mental acts are introspectible, and entertaining is one of those. Mandelbaum could claim that an act of entertaining nonetheless automatically causes a dispositional belief. But if the connection between the entertaining and the ensuing belief is merely causal, then the view is not eliminativist after all.12 In its eliminativist form, the view has to be that when one introspectively seems to oneself to perform an act of merely entertaining the proposition that the order and connection of ideas is the same as the order and connection of things, either (i) in reality one does not perform any act or (ii) in reality one performs an act of committing to the truth of the proposition, that is, believing it. Presumably, (i) is a nonstarter. As for (ii), as noted, part of what one encounters in introspecting belief is the 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 phenomenology of orientation on the 'true or false?' question. Yet when one seems to oneself introspectively to perform the act of entertaining the proposition that the order and connection of ideas is the same as the order and connection of things, one does not encounter any phenomenal orientation on that question.13 To conclude, in all likelihood entertaining is neither eliminable nor reducible. It exists and is irreducible to combinations of belief and desire. To that extent, it must be treated as a third leg in the stool of the attitudes. To understand the realm of the attitudes, then, it seems we must posit three primitive attitudes grasped by acquaintance: belief, desire, and entertaining. In this picture, we grasp what entertaining is (as well as what belief and desire are) by encountering its (and their) distinctive phenomenology in our stream of consciousness.14 In what follows, a characterization of this phenomenology will be attempted. Naturally, this is an elusive task. The next section discusses the phenomenology internal to the realm of entertaining. The two following sections discuss the phenomenology of entertaining in relation to cognitive attitudes (3rst) and conative and mixed attitudes (second). §8. P("'*!"'*)*2/ I'."#'&) .* E'."#.&$'$'2: E'."#.&$'$'2, C*'."!,)&.$'2, C*'+$1"#$'2, A,,#"("'1$'2 The central, characteristic phenomenal feature of entertaining is simply its doxastic neutrality: its lack of phenomenal orientation on either the truth or the goodness issue. It is worth noting, however, that there are forsooth two distinct modes in which entertaining may be done. There is, on the one hand, a kind of entertaining of p that is done with a view to a certain cognitive achievement, typically the establishment of some credence in p. We often entertain that p in the context of trying to 3gure out the plausibility of p, whether and to what extent we should believe that p. One might, for example, entertain the proposition that the order and connection of ideas is the same as the order and connection of things because one is concerned to know whether one should believe it. On the other hand, there is also another kind of entertaining that is purely contemplative, done with no doxastic business or concern in mind (and certainly not targeting any cognitive achievement). One might entertain a scenario in which world peace obtains (or the corresponding proposition) because one 3nds it curiously soothing to do so; or one might entertain a brief exchange with one's deceased grandfather (describable as a longish propositions), somewhat as a child entertains scenarios in which he has superpowers, again for some unclear emotional bene3t utterly unrelated to the plausibility of the proposition entertained. There is a noticeable, if quite subtle, phenomenological difference between these two modes of entertaining. The former involves, but the latter does not, a phenomenological element of doxastic or epistemic engagement with the proposition that p. Thus, some episodes can be described as engaged entertaining and some as disengaged entertaining. Although there is a phenomenological difference between these two types of entertaining episode, it is an open question whether the difference pertains to a proprietary phenomenology of entertaining or derives from surrounding mental states, notably desires and emotions. One view is that the entertaining itself feels the same in both cases; it is just that the engaged variety is accompanied by a desire to know whether the proposition entertained is true or plausible, whereas the disengaged variety is not. The episode's overall phenomenology certainly differs, but it is unclear whether the entertaining component of the episode does. Since entertaining is a primitive attitude not analyzable in terms of others, what is at stake is whether there are ENTERTAINING AS A PROPOSITIONAL ATTITUDE / 5 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 6 / AMERICAN PHILOSOPHICAL QUARTERLY two primitives or one associated with entertaining; if the entertaining itself is the same in the engaged and disengaged modes, we have only one primitive on our hands here; if it is different, we have two. From a methodological point of view, it is preferable to posit initially a single primitive, accounting for the difference between the two modes of entertaining in terms of surrounding desires-pending a reason to think this would not work. It may well be that some such reason could be adduced, but this essay will proceed as though entertaining is one. Still, it is important to keep in mind the difference between engaged and disengaged modes of entertaining. With some savagery to ordinary language, we might say that entertaining p in the engaged mode is a matter of considering p, while entertaining p in the disengaged mode is a matter of contemplating p. Thus, the engaged/disengaged distinction corresponds to a consideration/contemplation distinction. (The quali3cation 'with some savagery' is needed because in truth it is perfectly grammatical to use 'contemplating' to describe an engaged episode of entertaining or 'considering' to describe a disengaged one. Nonetheless, it would be fair to remark that the engaged usage belongs relatively more on the fringe of the range of ordinary uses of 'contemplating' but is relatively more central to, closer to the core of, the ordinary use of 'considering'-and vice versa. This makes it reasonable to introduce a quasi-technical usage of 'contemplating' denoting all and only disengaged episodes of entertaining and of 'considering' for all and only engaged episodes of entertaining.) In any case, we should not confuse the phenomenology of neutrality and the phenomenology of disengagement. Entertaining is doxastically neutral on the truth (and goodness) of p when performed both in an engaged and in a disengaged mode. This neutrality is, as noted, the central characteristic of the phenomenology of entertaining. The element of engagement does not undermine neutrality-it introduces a doxastic concern but not a doxastic position. Another, more generic phenomenal characteristic of entertaining is what we may call phenomenal intensity. It seems phenomenologically manifest that conscious experiences vary in their phenomenal intensity-how vividly they are present to consciousness, as it were-and can even differ along no other dimension but that of phenomenal intensity. When we discuss sensory conscious experiences, it is important to distinguish this kind of phenomenal intensity from a more straightforward type of sensory intensity. The phenomenal intensity of a visual experience of red is not a matter of the degree of brightness or saturation of the red experienced. Visual experiences of red can vary independently along the dimension of experienced brightness or saturation and the dimension of phenomenal intensity/vivacity, which has to do rather with the clarity and alertness with which they are present to consciousness.15 The claim being made here is that this is true of episodes of entertaining as well: one can entertain that p more vividly or less vividly, in a phenomenal sense of 'vividly,' such that the episodes differ in nothing but their phenomenal intensity. Thus, one might on a sunny afternoon calmly entertain the proposition that the enumeration in the Constitution of certain rights shall not be construed to deny or disparage others retained by the people; and a moment later, perhaps after a sip of espresso or a bite of raw chocolate, and due to increased interest, concentration, and intellectual energy, suddenly entertain the same proposition more alertly and clearly, that is, with noticeably greater phenomenal intensity or vivacity. A third phenomenal feature worth noting is what we may call presentational phenomenology. Chudnoff (2011) argues that certain purely intellectual states, such as intuitions, have this commonality with perceptual states, 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 that they boast a 'presentational phenomenology.' The presentational phenomenology of perceptual states consists in the fact that whenever one undergoes a perceptual experience, in addition to being related to the proposition that is the content of the experience, one is also perceptually aware of a certain item.16 For example, looking at the clock, you may see that it is getting late. Here, although your perceptual state has the propositional content that it is getting late, it also involves a sort of nonpropositional item-awareness of the clock. This is the presentational phenomenology of perception. Chudnoff argues that intuitions have a similar feature: when one intuits that p, there is always some abstract object O, such that intuiting that p involves being aware of (presented with) O. Typically, says Chudnoff, O is an essence of some property or particular.17 For example, when one intuits that the taller-than relation is transitive, one is aware of the essence of the taller-than relation (a universal). Although the intuition has a propositional content (that the taller-than relation is transitive), it also involves an item-awareness (of the relation's essence). This is the presentational phenomenology of intuition. The claim made here is that entertaining often, perhaps typically, involves a presentational phenomenology as well. This is especially clear in the disengaged, contemplative variety of entertaining. Let us contemplate the proposition that Congress shall make no law respecting an establishment of religion. When one examines the phenomenology of this contemplative episode, one 3nds that it is quite complex. It may involve, for example, a visual image of the U.S. Capitol building in Washington and an auditory image of the word establishment in silent speech. In addition, however, it seems to involve a purely intellectual awareness of certain items: religion in general, law in general, government in general. It is not immediately obvious how to best describe how (under what mode of presentation) these items are presented in the phenomenology: whether as essences, as properties, as notions, or as some other type of entity. It may be that the presentational phenomenology itself is simply silent on this matter. It is clear that it presents those items not in any particular spatiotemporal manifestation (this instance of religiosity, that instance of governing), but in general. In that sense (but only in that sense), it presents them as abstract entities.18 What we may say with con3dence is that there is a sense, however vague and open-ended, of a commonality among standard instance of religiosity, of lawfulness, and of governing, as well as of a peculiarity of theirs; and that it is this commonality-cum-peculiarity that is presented in the entertaining. The ontological status of such commonality-cum-peculiarity is something on which we may stay neutral. Introducing the term commonarity as shorthand for commonality-cum-peculiarity, it is thus reasonable to elucidate the thesis that entertaining has a presentational phenomenology as follows: if a subject entertains a proposition of the form <the Fs are Gs>, then normally S is item-aware of the Fs' commonarity and the Gs' commonarity; similarly for entertaining propositions whose contents are propositions with other logical forms.19 If this is right, then while entertaining that p is itself a propositional awareness, it typically involves in its phenomenology an element of item-awareness. The traditional philosophical notion of apprehending seems to comport well with the kind of theoretical role that this kind of item-awareness plays in the present phenomenological analysis of entertaining (inspired by Chudnoff's phenomenological analysis of intuition). If we construe the notion of apprehending as capturing the item-awareness built into entertaining, we can elucidate the thesis of presentational phenomenology further: if a subject entertains a proposition of the form <the Fs are Gs>, then normally S apprehends the Fs' commonarity and the Gs' commonarity. ENTERTAINING AS A PROPOSITIONAL ATTITUDE / 7 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 8 / AMERICAN PHILOSOPHICAL QUARTERLY In summary, the discussion above has identi3ed three phenomenal features of entertaining: orientational neutrality, phenomenal intensity, and presentational phenomenology. (The 3rst is the most essential.) In the course of the discussion, connections have been drawn among a number of other related notions. It was suggested that considering is the engaged mode of entertaining and contemplating its disengaged mode, and that apprehending is the presentational component of entertaining. In the next section, we turn to connections between entertaining and a more remote circle of notions more central to doxastically committal cognition. §9. R")&.$*' .* .(" C*2'$.$:" A..$.-1"+: E'."#.&$'$'2, T($';$'2, J-12$'2, B")$":$'2 The discussion in this section will progress through three main themes: the connection of entertaining to thinking (§4.1), judging (§4.2), and believing (§4.3). The discussion will have to be relatively brief, inasmuch as one could easily dedicate an essay or a book to the phenomenological relation between entertaining and each of these other attitudes. §4.1. Entertaining and Thinking What is the relation between episodes of entertaining and episodes of thinking? To answer this question, it is important to distinguish between thinking-that and thinking-of. As we will see, thinking-that is distinct from entertaining, though there may be interesting connections between them. Thinking-of, meanwhile, may be nothing more than entertaining. Thinking-of is doxastically noncommittal in a variety of ways. First, one can think of a particular a, or of a property F, without committing to the notion that a exists or that F is instantiated. Relatedly, one can think of a and of F without thereby thinking that a is F. In fact, at least in one legitimate hearing of the locution, one can think of a's being F without thinking that a is F (more on that momentarily).20 Thus, thinking-of is doxastically neutral in the manner characteristic of entertaining. At the same time, thinking-of cannot be identi3ed with entertaining. For one thing, thinking of a and thinking of F are not propositional attitudes, but 'objectual attitudes,' so they do not qualify as forms of entertaining a proposition-the kind of entertaining this essay is concerned with.21 If anything, it is more plausible to identify thinking-of with apprehending, which as noted above is an objectual constituent of the presentational phenomenology of entertaining. However, even this identi3cation is problematic. It is important to keep in mind that apprehending a or F presents itself as involving an appreciation of the 'commonarity' of a or F-whereas one may think of a or of F without having a sense of their commonarity. Thus, episodes of apprehending would appear to be a proper subset of episodes of thinking of, namely, propositional thinking-of. Consider now thinking that a is F. This sort of episode is clearly not doxastically neutral: one commits to the obtaining of a state of affairs and arguably also to the existence of a particular and to the instantiated-ness of a property. Thus, thinking that a is F is de3nitely not a form of entertaining, since it involves full-blooded doxastic commitment. This is not the minor doxastic engagement involved in considering p; it is the much more involved state of considering and then af3rming that p. (Note well: the temporal language here-'and then'-is meant metaphorically; in many acts of thinking-that, the considering and the af3rming are simultaneous, that is, are logical rather than temporal components.22) There is something of a tradition of assimilating thinking to entertaining, but authors who have done so have failed to notice the distinction between thinking-of and thinking-that. Thus, Cassam (2010) points out that "someone who wonders whether P is thinking-thinking about P, as we would 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 say-but is not mentally af3rming that P" (p. 84). However, such a person, although thinking about, or of, p, is not thinking that p. Thinking that p does require mentally af3rming p. To summarize the discussion thus far: thinking comes in two separate varieties, thinking-of and thinking-that, and there is a close connection between the former and entertaining insofar as both are doxastically neutral; however, any connection between the latter and entertaining would have to be much more complicated. An interesting question is how to treat reports such as 'S is thinking of a's being F,' that is, reports that use imperfect nominals as the grammatical objects of 'thinking of.'23 One view is that thinking of a's being F is the same as thinking that a is F and therefore should be treated as a variant of thinking-that. Another view is that just as thinking of a does not require thinking that a exists and thinking of F does not require thinking that F is instantiated, so thinking of a's being F does not require thinking that a's being F obtains (hence that a in fact is F). A third view is that reports of the form 'S is thinking of a's being F' are used sometimes as suggested in the 3rst view and sometimes as suggested in the second view. Plausibly, the second view is the most accurate, in that although the relevant reports can certainly be used along the lines suggested in the 3rst view, competent speakers would typically use them along the lines suggested in the second view. In any case, on both the second and third view, there is a central appropriate use of such reports in which thinking of a's being F is doxastically neutral and noncommittal on the question of whether a is F. In addition to distinguishing thinking-of and thinking-that, we should distinguish occurrent thinking-that and standing thinkingthat. Occurrent thinking-that can be correctly ascribed only when a certain mental event takes place in the subject, typically in the form of the subject performing the right kind of cognitive act. At the very least, occurrently thinking that a is F is performing a mental act of predicating F of a. By contrast, standing thinking-that can be correctly ascribed even when the subject performs no mental act, even when no mental event takes place in her-indeed, even when she is fast asleep. (Compare thinking-of, which can be correctly ascribed only when the subject performs some mental act; it is always false to say of someone in a dreamless sleep that she is thinking of this or that. Clearly, thinking-of has only an occurrent variety.) In a quasi-stipulative vein, we may use the terms belief and judgment to denote these two varieties of thinking-that. For belief is not an act, but a state, whereas judgment is an act rather than a state. We can appreciate this by the appropriateness of the progressive tense for each. It is grammatical to say not only that S judges that p, but also that S is judging that p; by contrast, it is ungrammatical to say that S is believing that p-one can only say that S believes that p (see Williamson 2000, p. 35). Accordingly, one can correctly say of someone in a dreamless sleep that she believes that p, but not that she judges that p. Thus, it is natural to identify occurrent thinking-that with judging and standing thinking-that with believing. In this bookkeeping scheme, thinking divides into thinking-of and thinking-that, and the latter divides into occurrent thinkingthat, or judgment, and standing thinking-that, or belief. Entertaining is closely linked to thinking-of, insofar as a subset of thinkingsof (those that constitute apprehending) are components of entertaining's presentational phenomenology. The link between entertaining and the two forms of thinking-that remains to be explored. §4.2. Entertaining and Judging Given the above connections between entertaining, thinking-of, and occurrent thinking-that, it might be suggested that one ENTERTAINING AS A PROPOSITIONAL ATTITUDE / 9 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 10 / AMERICAN PHILOSOPHICAL QUARTERLY could in fact analyze entertaining in terms of judging. The analysis would construe entertaining as a judgment from which the element of af3rmation has been somehow removed. The predication of F of a is bracketed, as it were, so that one 'withholds judgment,' with the result that one is merely entertaining that a is F. In a slogan, entertaining equals judging minus af3rming. Note well: the slogan is not meant as a psychological claim about the causal formation of entertainings;24 rather, it is intended as an analytical claim about the logical structure of entertaining. It is hard to see what supports the analysis of entertaining as judging minus af3rming. It is particularly hard to see what is supposed to make it preferable over the opposite analysis, which could be summarized in a competing slogan: judging equals entertaining plus af3rming. After all, it is in general much more natural to analyze a whole in terms of its parts than a part in terms of the whole and other parts. Certainly this is so when the parts are self-standing items that can occur in the absence of the whole. We are not tempted to understand a door as a house minus walls and windows. It is equally odd to understand entertaining in terms of a subtraction from judging. Furthermore, arguably 'judging minus af3rming' would at most capture considering, the engaged variety of entertaining, as it suggests a mental activity in which the plausibility of the proposition entertained is in the subject's sights. On the proposal being discussed, entertaining is a matter of withholding judgment. But a person only withholds judgment when the question of whether to assent to a proposition or dissent from it arises. Withholding judgment puts the issue of af3rmation on the table, so to speak. By contrast, in contemplating a proposition (i.e., entertaining it in the disengaged mode) af3rmation does not enter the picture-it is neither asserted nor withdrawn, but simply absent. It would seem, then, that 'judging minus af3rming' misses out on contemplating. Thus 'judging minus af3rming' is too narrow to capture entertaining as such. There is good reason to think that 'judging minus af3rming' is also too broad to capture entertaining. For there are other propositional attitudes that could be described this way: doubting comes to mind immediately. When one comes to doubt what one previously believed-for example, that truth-conditional semantics is more plausible than justi3cationconditional semantics-one enters a state naturally described as judging minus af3rming.25 But entertaining that p is clearly not the same as doubting that p. All this recommends rejecting an analysis of entertaining as 'judging minus af3rming.' This leaves two options open regarding the relationship between entertaining and judging: either (i) we analyze judging as entertaining plus af3rming, or (ii) we treat judging and entertaining as mutually unanalyzable primitives. What is at stake in this choice is not the number of primitives. If (ii) is true, then entertaining and judging are primitives, and if (i) is true, judging is not a primitive but (for all that has been said) af3rming is. Whether our primitives here are entertaining and judging or entertaining and af3rming, they are two. So the number of primitives is not at stake. Other matters, however, are at stake. First of all, if (ii) is true, then judging and entertaining has a certain phenomenal commonality, since entertaining is a component or aspect of judging. By contrast, if (i) is true, then there need not be any phenomenal commonality or overlap between entertaining and judging. Second, the two views differ on the question of whether judging is phenomenologically simple or structured: according to (i), it is simple; according to (ii), it is structured. Relatedly, while both views posit an entertaining primitive and a cognitive primitive, according to (i) the cognitive primitive is an attitude (judging), whereas 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 according to (ii) it is an attitude-component (af3rming). These are substantive differences between the two views. Even with these substantive differences clearly laid out, it is dif3cult to assess which view is more plausible. Arguably, the view that judging is reducible to entertaining plus af3rming-(ii) above-is more elegant. But it is unclear whether this should be taken to suggest it is also more plausible. Consider the issue of phenomenal commonality. One advantage of the view that judging is entertaining plus af3rming is its potential to offer a uni3ed account of several propositional attitudes. One could maintain that judging is entertaining with an overlay of af3rmation, doubting is entertaining with an overlay of positive nonaf3rmation, supposing is entertaining with an overlay of mock af3rmation, and so on.26 The emerging picture is of a group of cognitive acts with an entertaining core modulated by an af3rmation-related element. There is a certain elegance in this uni3ed picture. But whether the picture is consequently more plausible depends on whether we are pre-theoretically inclined to 3nd phenomenal commonality among all these types of cognitive act. Arguably, there is indeed a phenomenal commonality, namely, the feel of grasping the proposition, or having it before one's mind. (In the case of entertaining, that grasp constitutes the whole of the attitude, but in the case of other cognitive attitudes, only a proper part). Clearly, however, some might reject this introspective claim, professing to 3nd no such common core of pure grasping in their various cognitive acts. In other words, theoretical unity is truth-conducive (hence indicative of plausibility) only where there is corresponding unity in the phenomena, but it is not obvious in this case that the phenomena have the degree of unity claimed-that there is indeed a phenomenal commonality among judging, doubting, suspecting, and so on. One argument for the existence of such unity in the phenomena appeals to the independent idea that appreciating what one is judging, doubting, or supposing would require having the relevant proposition before one's mind, and having the relevant proposition before one's mind just is entertaining the proposition. The idea is that without a common core of entertaining, it is unclear how subjects would know exactly what they were judging, doubting, or supposing. Even in 'automatic,' unre4ective judgments (e.g., that the table is brown), where there is no temporal gap between entertaining and af3rming, the af3rmation that a is indeed F requires that the subject apprehend <a> and <F> and entertain their propositional unity.27 The whole proposition needs to be before the subject's mind. This consideration may suggest that entertaining is indeed a logical component of all or most (occurrent) cognitive attitudes. It is not entirely obvious what to make of this argument, but something about it smells right. If we accept it, then we have pro tanto reason to take entertaining to be a unifying component of all or most cognitive attitudes.28 §4.3. Entertaining and Belief What about the standing, dispositional cognitive attitudes, such as belief? Clearly, entertaining cannot be a component of belief, precisely because entertaining is an occurrent act whereas belief is a standing state. It may nonetheless be possible to understand belief centrally in terms of entertaining, as will now be argued. The main idea is simply to combine the view that judgment is entertaining plus af3rming with the view that believing is just being disposed to judge. It would follow that believing is just being disposed to entertain-and-af3rm. Let us start with Searle's (1990; 1992, chap. 7) 'connection principle': the claim that every unconscious intentional state must be potentially conscious. This principle conENTERTAINING AS A PROPOSITIONAL ATTITUDE / 11 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 12 / AMERICAN PHILOSOPHICAL QUARTERLY nects the unconscious to the conscious. We might suggest a parallel principle connecting the standing to the occurrent: every standing intentional state must be potentially occurrent; or better, for a subject to be in a standing state with propositional content p, the subject must be disposed to be in a corresponding occurrent state with propositional content p. That is: a subject S is in a standing intentional state directed at p only if S is disposed to enter occurrent intentional states directed at p. If we adopt such a principle, one substitution instance would be the following: S standingly thinks that p only if S is disposed to occurrently think that p. Recall, now, that we have determined to use the term belief for such standing thinking-that, and 'judgment' for occurrent thinking-that. So the principle could be more succinctly expressed as follows: S believes that p only if S is disposed to judge that p.29 This connection principle is highly plausible. The argument for it may be summarized thus: if S is not disposed to occurrently think that p, then S does not dispositionally think that p; if S does not dispositionally think that p, then S does not standingly think that p; if S does not standingly think that p, then S does not believe that p; therefore, if S is not disposed to judge that p, then S does not believe that p. With this belief-judgment connection principle in place, we may now plug into it the account of judgment in terms of entertaining-and-af3rming. What we obtain is the following belief-entertainment connection principle: S believes that p only if S is disposed to entertain-and-af3rm that p.30 Being a one-way conditional, the beliefentertainment connection principle does not quite provide an analysis, or account, of belief. It does, however, provide an interesting and far-from-trivial conceptual connection between the two, one that is at once somewhat surprising and not at all implausible against the background of the right assumptions. Furthermore, it may be turned into a potential analysis if a case could be made for the converse one-way conditional-the claim that if S is disposed to judge that p, then S believes that p. For then the disposition to judge would be not only necessary but also suf3cient for belief. In fact, this sufficiency claim seems if anything less controversial than the necessity claim. Plausibly, any explanatory work one might summon dispositional thinking-that to perform could be shouldered more economically by dispositions to think-that (see Audi 1994). If so, there is no conceivable rationale for positing any aspect of dispositional thinking-that (i.e., believing) over and above what is involved in the disposition to thinkthat (i.e., disposition to judge). With the two conditionals in place, we can embrace the corresponding biconditional: S believes that p iff S is disposed to judge that p. The biconditional itself could serve as an analysis of judgment in terms of belief just as well as one of belief in terms of judgment. But in line with the uni3catory aspiration presented above, we may plausibly offer the biconditional as a prima facie analysis of belief in terms of judgment. This direction of analysis is also recommended by the general thought that it is preferable to understand the dispositional in terms of the occurrent than the occurrent in terms of the dispositional. According to the emerging analysis, then, for S to believe that p is just for S to be disposed to judge that p. In other words, when 'S believes that p' is true, it is true in virtue of S being disposed to judge that p. If we do adopt an analysis of belief in terms of judgment, we may further combine it with the analysis of judgment in terms of entertaining plus af3rming from the previous subsection. The result would be that belief is just the disposition to entertain-and-af3rm. For S to believe that p would be for S to be disposed to entertain p and af3rm what S entertains. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 The analysis of belief in terms of a disposition to entertain and af3rm is not entirely straightforward, however. Certainly, it could not be understood as claiming that S has both a disposition to entertain and a disposition of af3rm. For one thing, it is very natural to say that most subjects believe that 231.857 is greater than 143.769 but do not have the disposition to entertain this proposition at all, much less to entertain and af3rm it. It might be thought that this dif3culty could be overcome simply by attributing to the subject a merely conditional disposition, namely the disposition to af3rm that p if she entertains that p.31 This new requirement is too broad, however. We can conceive of a subject S and a proposition p such that S does not in fact believe that p, but if S entertained that p, S would come to see the plausibility of p and thus would come to judge that p. This nonbeliever thus satis3es the conditional requirement that she would be disposed to af3rm p if she entertained p. Therefore, this cannot be a requirement on believing. In other words, subjects have more conditional dispositions of this sort than they have beliefs.32 To neutralize this dif3culty, we need to home in on a more speci3c (entertainingrelated) disposition, one that subjects have (when and) only when they believe that p. A full specification of the character of a disposition-the kind of speci3cation suf3cient to individuate the relevant disposition-must refer to (i) triggering conditions and (ii) manifestation conditions. Thus, the vase's disposition to break when dropped has dropping as its triggering condition and breaking as its manifestation condition. Let us now propose triggering and manifestation conditions for the kind of disposition that is plausibly coextensive with belief. First, a subject may have the disposition to entertain and af3rm that 231.857>143.769 in a variety of relatively speci3c triggering circumstances. One obvious triggering circumstance involves the subject being asked whether 231.857>143.769. But there are many other circumstances that might causally trigger the subject's entertaining of this proposition: a business transaction requiring a cost-bene3t analysis in which the costs and bene3ts sum up in the right way, a calculation of the lengths in miles or kilometers of two routes from her place of residence to her destination, and so on. Let us collect all these triggering circumstances of the disposition to entertain that p under the label 'p-entertaining-triggers.' Crucially, any subject who believes that p all along would in fact be disposed to judge that p when the p-entertaining-triggers obtain.33 Thus, it is quite plausible that the p-entertaining-triggers are the triggering conditions of the disposition coextensive with believing that p. As for the manifestation conditions, these cannot be just the circumstances in which the subject ends up af3rming that p, since as we just saw, some subjects may come to acquire new beliefs as a result of entertaining certain propositions. However, when subjects acquire new beliefs in this way, the af3rmation of the proposition entertained is not immediate but instead is mediated by further reasoning and/or research. The difference between, on the one hand, a subject who believes that Twardowski lived and worked in Lvov, and on the other hand, a subject who does not believe this but might come to believe this were they to entertain the proposition, is that the latter would require at least one more thought in order to af3rm the proposition. Typically, this would require some preliminary research, but even if the subject is lazy and af3rms the proposition because, say, both 'Twardowski' and 'Lvov' are Polish-sounding names, she would still need to have that extra thought about Polish sounds. By contrast, it is at least possible for a subject who already believes that Twardowski lived and worked in Lvov to af3rm this proposition upon entertaining it without at the same time having any other thought, and more generally without ENTERTAINING AS A PROPOSITIONAL ATTITUDE / 13 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 14 / AMERICAN PHILOSOPHICAL QUARTERLY the mediation of any other mental state. Let us call the manifestation conditions special to this believer the 'immediate-af3rmation conditions.' These are the manifestation conditions that characterize the disposition which plausibly coextends with belief. The result is an analysis according to which S believes that p iff S is disposed to immediately af3rm that p when p-entertainingtriggers obtain. Interestingly, this analysis reveals quite a bit of structure in the notion of belief, which is often taken to be an attitudinal simple in contemporary philosophy of mind. Needless to repeat, belief is also often treated as primitive, or fundamental, hence as not analyzable in terms of any other propositional attitudes-something that would turn out to be false if we adopt the present analysis. As emphasized above, this does not mean that the theory of the attitudes has no need for a cognitive primitive in addition to the primitive of entertaining; rather, it means that the cognitive primitive is af3rmation, rather than belief or judgment, where af3rmation is a phenomenal component of judgment that 'attaches to' entertaining when we judge.34 Once belief is understood in terms of entertaining, a number of related cognitive attitudes follow suit. Thus, insofar as being convinced that p is just strongly believing that p and suspecting that p is just weakly believing that p, we can expect both to be analyzable in terms of entertaining. There are interesting questions about how exactly the analysis should go, but the expectation is that some entertaining-based analysis would work.35 To conclude this section, entertaining has close connections, and seems to be at the heart of, many of the central cognitive attitudes: thought, judgment, doubt, supposition, belief, conviction, suspicion. Most importantly, far from being primitive, belief (standing thinking-that) can be analyzed as the right disposition to entertain and af3rm. Still, there must be a cognitive primitive in the theory of attitudes. This is either the attitude of judging (occurrent thinking-that) or the element of af3rming, a phenomenal component of judging. Some considerations have been offered above in support of the latter option, but those are somewhat inconclusive. §<. R")&.$*' .* C*'&.$:" &'1 M$="1 A..$.-1"+: E'."#.&$'$'2, D"+$#", &'1 E!*.$*'+ The previous section explored the prospects for a uni3ed account of the cognitive attitudes in terms of a core attitude of entertaining. The discussion did not touch on the other half of 'belief-desire psychology,' to do with conative propositional attitudes. Since entertaining itself is 'orientationally neutral,' there is no prima facie reason it should be 3tter to analyze attitudes with an orientation on the 'true or false?' question than ones with an orientation on the 'good or bad?' question. Thus, one might think that just as judging can be understood as entertaining plus a fundamental act of af3rming, so there might be a fundamental act naturally associated with conative attitudes, such that desiring could be understood as entertaining plus it. This act would have to be a sort of conative rati3cation of the content entertained by the subject-what we might call, with a somewhat technical notion in mind, an act of approving. The idea, then, is that to occurrently desire that a be F is to entertain that a is F and approve of a's being F, that is, to perform an operation of approval over the proposition entertained. As before, this sort of analysis does not dispense with a conative primitive. Instead, it takes the conative primitive to be a phenomenal component of a propositional attitude rather than a propositional attitude. There is no economy of primitives here, but there is a claim of phenomenal commonality between entertaining, judging, and desiring-they all involve a fundamental phenomenology of grasping a proposition, of having a proposition before one's mind. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 Also, as before, once we understand occurrent desire in terms of entertaining plus approving, we can understand standing desire (e.g., the desire to stay alive, or to be happy) as a disposition to occurrently desire.36 The result, to a 3rst approximation, is this: S 'standingly' desires that a be F iff S has the right disposition to entertain that a is F and approve of a's being F. A more accurate approximation would articulate more precisely the triggering and manifestation conditions of the 'right' disposition.37 In addition to cognitive and conative attitudes, there are 'mixed' attitudes that involve a combination of both: being glad that, being disappointed that, being frustrated that, and so on. Presumably, these would be amenable to understanding in terms of entertaining modulated by both an af3rmation-related act and an approval-related act. Consider the standard functionalist analysis of being glad that p as simply the compresence of believing that p and desiring that p. This would be replaced, in the present picture, with the following: being occurrently glad that p is nothing but entertaining that p while both af3rming and approving of that which is entertained; being standingly glad that p is nothing but the disposition to occurrently being glad that p.38 Similar remarks apply to other propositional attitudes with 'mixed' directions of fit, including-centrally-the emotional attitudes, such as disappointment, frustration, hope, and fear (all of which include an element of assent or dissent and an element of approval or disapproval). The emerging picture replaces the functionalist belief-desire story, where all propositional attitudes are accounted for in terms of belief and desire, with an entertaining story, so to speak. In this entertaining story, all occurrent propositional attitudes are accounted for in terms of a core episode of entertaining modulated by an af3rmation-related and/or approval-related elements, and all standing propositional attitudes in terms of dispositions to undergo the relevant episodes. §>. C*'%)-+$*': T(" R&!+"/ S"'."'%" *7 E'."#.&$'$'2 The project of understanding all the propositional attitudes (partly) in terms of entertaining is extremely ambitious. But the claim that entertaining cannot be understood in terms of belief and desire (nor any other pair of cognitive and conative attitude) is much more modest, and it already presents a deep challenge to the functionalist orthodoxy. It requires that we posit a third primitive attitude and, moreover, one that does not 3t the functionalist mold very well. We can appreciate that by noting that the functionalist theorizes about mental states mostly in terms of their functional role and intentional content and appeals to causal connections among mental states and to the environment to account for both in naturalistically kosher terms. However, for both functional role and intentional content, it is less obvious how these causal treatments might proceed with regard to entertaining (which perhaps explains the tendency of functionalists to ignore entertaining).39 Consider 3rst functional role. At the level of token acts of entertaining, there are many that seem completely divorced from behavior. One might entertain the proposition that one can 4y to Persia without being in the least disposed to behave in any particular way. One could even do so without being disposed to reason in any way, namely, if one entertained the proposition in the disengaged mode (i.e., if one contemplated the proposition). Indeed, if two subjects contemplate that p, but one's contemplative episode is more phenomenally vivid than the other's, it is not clear what difference there might be in the functional pro3le of the two episodes. It is hard to rule out the possibility that some story could ultimately be told to the effect that there is; still, it is less obvious how such a story would proceed. ENTERTAINING AS A PROPOSITIONAL ATTITUDE / 15 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 16 / AMERICAN PHILOSOPHICAL QUARTERLY Similarly for intentional content. The standard approach to this in the functionalist orthodoxy is to account for the attitudes' intentional content in terms of broadly causal relations to the environment. The direction of the causal relation appealed to changes with the attitude's direction of 3t: a belief's content is determined by the part of the world that it is caused by in the right way, a desire's by the part of the world that it causes in the right way (see, e.g., Dretske 1988). Since entertaining has no direction of 3t, it is unclear what causal connections it might bear to the environment. Certainly at the level of token acts of entertaining, no such connection appears to hold; when one contemplates the proposition that one can 4y to Persia, one's contemplation neither causes nor is caused by the state of affairs of one's being able to 4y to Persia. More generally, contemplating some state of affairs is dissociated from the subject's environment in a way belief and desire are not. Perhaps a special causal-naturalist approach could be devised from within the functionalist framework, but again it is less obvious what the story would be.40 More generally, it seems to me that the great emphasis in the philosophy of mind of the past half-century on naturalizing mental phenomena, typically through reductive explanation in terms of structure and/or function, has often tempted philosophers to overlook mental phenomena whose essential pro3le seems independent of structure and function. In appearing cut off from the environment, on the one hand, and behavior, on the other, entertaining appears to resist understanding in terms of structure and function. To that extent, it represents a distinctive challenge for the program of naturalizing the propositional attitudes.41 It is doubtful that entertaining de3es demysti3cation in the sense of being ultima facie mysterious, but one may reasonably suspect that its scant treatment in contemporary philosophy of mind may be owed to this deep prima facie challenge it raises for the project of functionalist naturalization. In this respect, the disregarding of entertaining is patterned somewhat after the disregard for phenomenal consciousness that has characterized the philosophy of mind and cognitive sciences of the second half of the twentieth century. A consequence of this neglect is that our present understanding of entertaining is surprisingly patchy. This predicament would be disconcerting for any propositional attitude but is especially so when the attitude in question is one of three primitives in the theory of the attitudes. The goal of this essay has been to make initial observations about entertaining and draw basic distinctions with and connections to other notions by way of offering a nonreductive characterization of entertaining.42 In the process, a number of theses about entertaining have been articulated that collectively generate a rather speci3c pro3le. Here are ten central theses: of belief and desire. orientation. of entertaining that p, engaged and disengaged, which may be thought of as considering and contemplating (respectively). volves a presentational phenomenology whereby the subject apprehends some item(s). prehending and can thus be constituents of entertaining. nothing but entertaining with an overlay of af3rmation. is nothing but the right disposition to entertain-and-af3rm. taining with an overlay of approval. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 dispositions to entertain-and-approve. taining with an overlay of af3rmation and approval, and standing gladness is nothing but the right disposition to entertain-and-af3rm-and-approve. Other theses of a similar bent arise for other central cognitive, conative, and mixed attitudes: doubting, supposing, suspecting, wishing, intending, hoping, fearing, being disappointed, being frustrated, and more. With a long enough list of theses of this sort, one could offer a regimented nonreductive account of entertaining in the standard way: by formulating a Ramsey sentence (see Lewis 1972). Such a Ramsey sentence is often produced by collecting a large number of platitudes about that for which one wishes to account, stringing them into a long conjunction, replacing occurrences of the term for that which is to be accounted for with a free variable, and pre3xing the whole thing with the existential quanti3er. But the device of a Ramsey sentence as such is more 4exible than this in a number of ways, only two of which will be relevant here. First, the statements strung together need not be platitudinous. Thus, the above ten theses about entertaining are not platitudes, yet we can string them into a statement of Ramsey-sentence logical form all the same. This would read: 'there is an x, such that x cannot be analyzed in terms of belief and desire, and there is a distinction between engaged and disengaged kinds of x, and . . .' and so on. Second, there is no need to insist that all ten theses must turn out true for the account of entertaining to be viable. Perhaps we should expect only seven or eight of them to turn out true. If so, the Ramsey sentences should not involve simply a conjunction of all ten theses. Rather, it should consist in a (long!) disjunction of conjunctions of most of these ten theses. For example, one could produce all the possible lists of eight among these ten theses, generate a conjunction of the eight theses in each list, and then make a disjunction of all of these conjunctions. The resulting Ramsey sentence would be true if at least eight out of the ten theses are true. We may call this a 'cautious Ramsey sentence.' As noted above, ultimately there might be further theses connecting entertaining to doubting, supposing, suspecting, wishing, intending, hoping, fearing, being disappointed, being frustrated, and so on. The ultimate account of entertaining that should emerge from the present discussion would consist of the cautious Ramsey sentence based on all of these theses. The probability that all ten theses are true may be limited, but the probability of each is rather high (especially the 3rst four). In consequence, the probability that a substantial subset of these theses are true-a subset substantial enough to produce a robust nonreductive characterization of entertaining in the form of a cautious Ramsey sentence-is quite high. The hope is that the package emerging from these ten theses will strike the reader not only as enjoyable for contemplating but also as worthy of considering.

ENTERTAINING AS A PROPOSITIONAL ATTITUDE / 17 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 18 / AMERICAN PHILOSOPHICAL QUARTERLY 1. For discussion of the project and its prospects, see Searle 1983, chap. 1. For a particularly impressive pursuit of the project as it pertains to emotional propositional attitudes, see Gordon 1987. 2. Arguably, belief that p is connected to perceiving that p in a way that exactly parallels how desire to " is connected to trying to ", so that their permutation would not perturb these connections. 3. Arguably, the mental domain is the only domain where there is any pressure to posit direct acquaintance with intrinsic natures independently of the need for it to anchor our grasp of a functional web of nodes. 4. For Cohen (1992), belief that p is only the disposition to "normally to feel it true that p and false that not-p, whether or not one is willing to act, speak, or reason accordingly" (p. 4). And in one sense-the sense of a 'standing' belief, this is certainly plausible. But to the extent that we are willing to speak of conscious believing, or at least conscious thinking (more on this below), we may consider the relevant creedal feeling as the feeling of believing, rather than merely dispositionally connected to belief. 5. For relevant work, though, see Anscombe 1957 and Searle 1983. 6. Entertaining that p seems to be the same as entertaining the proposition at p. The relation between this and entertaining either the thought that p or the possibility that p is a contentious matter. Entertaining an idea or an image does not seem to be a propositional attitude at all, but what we might call an objectual attitude. This essay's concern, however, is with the impact of a correct understanding of entertaining on our grasp of the propositional attitudes. 7. One can entertain the proposition that dragons are friendly without either desiring them to be friendly or desiring them to be unfriendly, indeed without desiring anything. 8. A companion piece (Kriegel MS) develops the case for the irreducibility of entertaining much more fully. 9. Furthermore, the 3t relation is built into the attitude of a mental state and is external to the state's content in such a way that no speci3cation of the content can cancel it out. If the 3t relation was built into the content, such that believing that p and desiring that p were really two mental states with the same attitude toward different contents-say, the former toward 'p obtains' and the latter toward 'p should/ought to obtain'-we might be able to analyze entertaining that p as, say, believing that p while supposing that p does not obtain. 10. It should be stressed that the kind of nonreductivism encouraged here is not with respect to the reducibility of entertaining to neurophysiological facts, but only with respect to its reducibility to facts about belief and desire. It is perfectly possible to offer an account of entertaining as a primitive propositional attitude and at the same time offer a reductive explanation of it in terms of some neural property N. In fact, it is even possible to take entertaining to be primitive and yet offer a reductive functionalist account of entertaining (see Ryder Forthcoming). For just as in taking belief and desire to be primitive among the propositional attitudes, functionalists are not committing to the functional inexplicability of entertaining, so in taking entertaining to be primitive as well, one is not committing to its functional inexplicability. 11. This claim is supported by empirical work due to Gilbert 1991, according to which the traditional model, whereby when presented with a proposition we 3rst entertain it and only later come to believe or disbelieve it, is false to the facts. In reality, when presented with a proposition, we automatically believe it and only later may suspend or even reverse our initial belief. The empirical evidence for this is varied, but the 3ndings revolve around the following point: when comparing two groups of subjects presented with the same propositions, such that one group's cognitive functioning is interfered with (interference condition) and one group's is not (control condition), subjects in the interference condition behave in a way that suggests greater, rather than lesser, belief in those propositions than subjects in the control condition (Gilbert, Tafarodi, and Malone 1993). 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 12. In fact, such a view would not even be reductivist, as it would deny any constitutive connection between entertaining and belief. This is important, because in some of Mandelbaum's presentations of his view-in particular, pictorial ones (e.g., 2010, p. 24)-entertaining seems to be portrayed as indeed automatically causing believing. Since here the connection between entertaining and believing is merely causal, as such it would not affect the present dialectic, as argued in the text. 13. Mandelbaum would probably deny that there is such a feature as phenomenal orientation which distinguishes belief, desire, and entertaining, as he holds that only the contents of propositional attitudes are introspectively accessible-the attitudes themselves are inaccessible. As a general claim this cannot be true, however; surely one can tell by introspection not only that the content of one's current attitude is that one owns a private jet, but also that one's attitude is desire rather than belief. One is not confused as to whether one believes that one owns a jet or would like to own one. It may yet be that there is indeed no such feature of phenomenal orientation, of course. But then some other phenomenal feature must be offered to underwrite the nonpermutability of belief and desire, and one prediction is that whatever that phenomenal feature turns out to be, the act that introspectively seems to one to be the mere entertaining of a proposition would not exhibit it. 14. In fact, the view this essay will end up defending is somewhat different from this. But this is the minimal departure from the functionalist orthodoxy we must make to accommodate entertaining. 15. This can be seen most clearly by comparing visual perceptual experiences and visual after-images in which the brightness and saturation are the same but the phenomenal intensity is different. 16. According to Chudnoff, the item one is aware of is the truthmaker of the perception's propositional content. As this part of the view is more problematic than the rest in a variety of ways, it will not play a role in what is retained here from Chudnoff's characterization of presentational phenomenology. 17. Naturally, not any abstract object-not even any essence-would do. There needs to be a certain intimate connection between O and p. One's awareness of this abstract object is of the sort Russell (1910) posited in discussing acquaintance with universals. 18. The quali3cation 'only in that sense' is needed because it is important to distinguish two notions of abstractness. In one sense, entities of kind K are abstract when Ks are non-spatiotemporal. In another, laxer sense more common among trope theorists, Ks are abstract when there can be more than one K at the same place at the same time. The presentational phenomenology of entertaining does not seem to me to take a stand on this. It does not, therefore, commit to the relevant items being non-spatiotemporal. 19. There is an interesting extension to propositions of the form <a is F>. For a has a peculiarity but not a commonality. We can, however, de3ne the notion of 'commonarity' so that a still has a commonarity. 20. In the formal mode, we might say more generally that adding a nominal complement to the verb 'thinking of' and adding a sentential complement to the verb 'thinking that' always results in a statement with different truth conditions-at least on one legitimate hearing/reading of the resulting statements. 21. There is a question as to whether thinking of a's being F is a propositional or objectual attitude. It seems that the terms propositional attitude and objectual attitude are not suf3ciently de3ned to discriminate here-we need to stipulate their meanings in such a way that it becomes determinate whether thinking of a's being F is propositional or objectual. 22. For the notion of a logical component, or logical part, see Kriegel 2009, chap. 6. 23. These nominals are called imperfect because they contain traces of the verb. They are contrasted with perfect nominals, such as 'a's F-ness,' in which the verb disappears altogether. 24. As such a claim, it is certainly not true to the facts; although sometimes one arrives at an episode of entertaining by 3rst judging that something is the case but then taking back the af3rmative compoENTERTAINING AS A PROPOSITIONAL ATTITUDE / 19 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 20 / AMERICAN PHILOSOPHICAL QUARTERLY nent of one's attitude, much more often one in fact proceeds in the opposite way, 3rst entertaining a proposition and then af3rming it to produce a judgment. 25. Even the act of supposing that p could be described as 'judging minus af3rming.' One can suppose that p without any commitment to the truth or obtaining of p-one can perfectly well withhold judgment. Yet supposing that p is not quite entertaining that p. For it involves a sort of mock af3rmation (at least provisionally mock af3rmation), whereas entertaining (whether contemplating or considering) involves no af3rmation-related component. (Like entertaining, supposing comes in both an engaged and a disengaged variety. In the disengaged variety, supposing that p is not doxastically or cognitively 'serious' and is to that extent entirely a matter of mockery-it involves nothing but mock af3rmation. However, in the engaged variety the act of supposition is very much serious. When we suppose a certain proposition in order to see what consequences it might have, for example, the mock-af3rmation is only provisional, insofar as the very point of the exercise is to consider whether one ought to af3rm the proposition supposed.) 26. However, the analysis of supposition should be in line with the distinction, in the preceding note, between two modes of supposition. 27. Here <a> and <F> are intended as the relevant constituents of <a is F>. But the claim could also be put in terms of the 'commonarity' of a and of F. 28. The view is not without precedent. It was certainly Brentano's (1874) view: one section of his Psychology from an Empirical Standpoint is titled "Mental Phenomena Are Presentations or Are Based on Presentations"-where presentation is his term for an orientationally neutral conscious act, such as entertaining or imagery. Current proponents of a picture similar to this in essential respects include Scott Soames (Forthcoming). 29. A strikingly similar analysis of believing that p as just being disposed to consciously judge that p is explicitly asserted, and defended in a sustained manner, by Smithies (MS). He himself supports the analysis by consideration of the appropriateness of epistemic-normative evaluation of judgment and belief in a discussion too nuanced to summarize here. 30. It might be objected that many believers are not at all disposed to entertain the propositions they believe, even though there is a sense in which they are disposed to judge these propositions true if they entertain them. This objection will be considered momentarily. 31. Here the subject is not required to be disposed to entertain that p. She is only required to be disposed in such a way that if and when she does entertain p, she af3rms what she entertains. This would lead to the following analysis: S believes that a is F iff S is disposed to entertain that a is F and af3rm that a is F. 32. So while the conditional proposition is a necessary condition for belief, it is not a suf3cient condition for it. 33. By de3nition, the presence of p-entertaining-triggers guarantees the subject's entertaining of p. But it is not by de3nition that the presence of p-entertaining-triggers would lead a subject to judge or af3rm that p. That part is substantive and depends on the subject actually believing the proposition. 34. There is clearly a close connection between af3rmation and the phenomenal orientation mentioned already in the Introduction. One option is to hold that af3rmation is fully phenomenally constituted by this phenomenal orientation. 35. The simplest analyses would go as follows: S is convinced that p iff S is disposed to entertain and strongly af3rm that p; S suspects that p iff S is disposed to entertain and weakly af3rm that p. The strength of af3rmation would be naturally construed as a kind of phenomenal intensity of af3rmation. It 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 would not be surprising, however, if it turned out that the ultimate analysis of conviction and suspicion is in truth much more complex. 36. This is analogous to the way standing thinking-that (believing) was understood as a disposition to occurrently think-that (judge). 37. There is also a completely different approach to attempting to analyze desire in terms of entertaining. This involves analyzing desire in terms of belief (and then belief in terms of entertaining, as per the previous section). Lewis (1988) argued that this desire-as-belief thesis is in tension with central tenets of decision theory, but some have denied that it is (e.g., Price 1989, Hájek and Pettit 2004). This is not the place to weigh in on that debate, but in any case the 'desire as belief thesis' is phenomenologically implausible, given that the phenomenal orientation of belief and desire are different. Insofar as we understand phenomenal orientation in terms of direction of 3t, the point is that propositional attitudes with a world-to-mind direction of 3t cannot be analyzed in terms (solely) of propositional attitudes with a mind-to-world direction of 3t. 38. The functionalist analysis identi3es no common attitude toward p in being glad that p (being glad that p is construed as simply a fortuitous compresence of two wholly separate attitudes toward p). By contrast, the entertaining-based analysis identi3es a single attitude toward the content that happens to be modulated in two separate ways. This is not intended as a major advantage for the 'entertaining analysis.' Still, it is plausibly a minor advantage. 39. To say this is not to suggest that it is impossible to make such causal treatments work, much less that entertaining de3es naturalization. It is merely to suggest that it is less obvious how the familiar style of causal treatment might proceed. 40. Ryder (Forthcoming) attempts to develop such a naturalistic account of entertaining. 41. There is some obvious connection here to Chalmers's 'hard problem' of consciousness, which is best articulated as the problem that consciousness seems to defy reductive explanation in terms of structure and function (see Chalmers 2002). The connection strikes me as not at all accidental: it is precisely because entertaining, too, does not lend itself very easily to explanation in term of structure and function that it is so natural to theorize about it from a phenomenological perspective and that its very nature seems to come through most clearly in its phenomenal character. 42. To repeat, the characterization is nonreductive in that it does not attempt to account for entertaining in terms of other attitudes. It is not meant to be nonreductive in the sense of positing entertaining as a nonphysical feature of the world. For all that has been said here, entertaining is nothing but E-3ber 3rings.
