I present a formal theory of the logic and aboutness of imagination. Aboutness is understood as the relation between meaningful items and what they concern, as per Yablo and Fine’s works on the notion. Imagination is understood as per Chalmers’ positive conceivability: the intentional state of a subject who conceives that p by imagining a situation—a configuration of objects and properties—verifying p. So far aboutness theory has been developed mainly for linguistic representation, but it is natural to (...) extend it to intentional states. The proposed framework combines a modal semantics with a mereology of contents: imagination operators are understood as variably strict quantifiers over worlds with a content-preservation constraint.

The present work outlines a logical and philosophical conception of propositions in relation to a group of puzzles that arise by quantifying over them: the Russell-Myhill paradox, the Prior-Kaplan paradox, and Prior's Theorem. I begin by motivating an interpretation of Russell-Myhill as depending on aboutness, which constrains the notion of propositional identity. I discuss two formalizations of of the paradox, showing that it does not depend on the syntax of propositional variables. I then extend to propositions a modal predicative (...) response to the paradoxes articulated by an abstraction principle for propositions. On this conception, propositions are “shadows” of the sentences that express them. Modal operators are used to uncover the implicit relation of dependence that characterizes propositions that are about propositions. The benefits of this approach are shown by application to other intensional puzzles. The resulting view is an alternative to the plenitudinous metaphysics of impredicative comprehension principles.

A central problem for any truthmaker theory is the problem of negative truths. In this paper, I develop a novel, piecemeal strategy for solving this problem. The strategy puts central focus on a truth-relevant notion of aboutness within a metaphysically modest version of truthmaker theory and uses key conceptual tools gained by taking a deeper look at the best attempts to solve the problem of intentionality. I begin this task by critically discussing past proposed solutions to P-NEG in light (...) of Russell’s debate with Demos. This reveals a central difficulty with addressing the problem, specifically that one cannot be committed to incompatibility facts in one’s account of negation and of the truth of negative truths. I then present an aboutness-based version of truthmaker theory. Utilising what I call the strict and full account of aboutness, I extract aboutness-based theories of truth and falsity. I use this machinery to present a promising new strategy for solving P-NEG which does not have the problems of alternative approaches. Finally, I present and respond to some potential objections.

In this paper, I first present an overview of Asay’s _A Theory of Truthmaking_, highlighting what I take to be some of its most attractive features, especially his re-invigoration of the ontological understanding of truthmaking and his defence of ontology-first truthmaking over explanation-first truthmaking. Then, I articulate what I take to be a puzzling potential inconsistency: (a) he appeals to considerations to do with aboutness in criticising how well ontological views account for truth while (b) ruling out aboutness (...) from the right account of truthmaking. He argues, instead, that necessitation is both necessary and sufficient for truthmaking (§3.3). I suggest that adding aboutness to one’s account in the right way is not just compatible with but important for ontology-first truthmaking. I do all this to invite Asay to clarify his position on these matters. Overall, Asay’s worldview displays the fruitfulness of an ontologically serious approach to metaphysics that puts truthmaking centre-stage. (shrink)

A Russellian notion of what it is for a proposition to be “directly about” something in particular is defined. Various strong and weak, and mediate and immediate, Russellian notions of general aboutness are then defined in terms of Russellian direct aboutness. In particular, a proposition is about something iff the proposition is either directly, or strongly indirectly, about that thing. A competing Russellian account, due to Kaplan, is criticized through a distinction between knowledge by description and denoting by (...) description. The epistemological significance of Russellian aboutness is assessed. A Russellian substitute for de re propositional attitude is considered. (shrink)

Strong non-maximalism holds that some truths require no ontological ground of any sort. Strong non-maximalism allows one to accept that some propositions are true without being forced to endorse any corresponding ontological commitments. We show that there is a version of truthmaker theory available—anti-aboutness truthmaking—that enjoys the dialectical benefits of the strong non-maximalist’s position. According to anti-aboutness truthmaking, all truths require grounds, but a proposition need not be grounded in the very thing(s) that the proposition is about. We (...) argue that if strong non-maximalism can be defended, then so can anti-aboutness truthmaking on the very same basis; one can enjoy the benefits of strong non-maximalism without giving up on the idea that truth is always grounded in being.

A de re objectual subject matter is a subject matter of the form how a1, a2 … are, whereas a de dicto objectual subject matter is a subject matter of the form how Fs are. An objectual subject matter is either a de re or de dicto objectual subject matter. This paper provides a systematic theory of aboutness towards objectual subject matters which, if correct, illuminates both the nature of intrinsicality and the general nature of aboutness. In addition (...) to the familiar distinction between partial and complete aboutness, I argue that there is a further orthogonal distinction between pervasive and hereditary aboutness, resulting in four ways in which a sentence, proposition or state of affairs can be about an objectual subject matter. I state and defend a number of basic principles concerning these varieties of aboutness as they apply to objectual subject matters and propose non-reductive analyses of them in terms of each other. I also propose an analysis of aboutness towards de re objectual subject matters in terms of aboutness towards de dicto objectual subject matters and put forward an attractive solution to a puzzle regarding aboutness due to Nelson Goodman.

The Information Artifact Ontology (IAO) was created to serve as a domain‐neutral resource for the representation of types of information content entities (ICEs) such as documents, data‐bases, and digital im‐ages. We identify a series of problems with the current version of the IAO and suggest solutions designed to advance our understanding of the relations between ICEs and associated cognitive representations in the minds of human subjects. This requires embedding IAO in a larger framework of ontologies, including most importantly the Mental (...) Func‐tioning Ontology (MFO). It also requires a careful treatment of the aboutness relations between ICEs and associated cognitive representa‐tions and their targets in reality, which implies in turn a new treatment of the relation of truthmaking.

Our topic is the theory of topics. My goal is to clarify and evaluate three competing traditions: what I call the way-based approach, the atom-based approach, and the subject-predicate approach. I develop criteria for adequacy using robust linguistic intuitions that feature prominently in the literature. Then I evaluate the extent to which various existing theories satisfy these constraints. I conclude that recent theories due to Parry, Perry, Lewis, and Yablo do not meet the constraints in total. I then introduce the (...) issue-based theory—a novel and natural entry in the atom-based tradition that meets our constraints. In a coda, I categorize a recent theory from Fine as atom-based, and contrast it to the issue-based theory, concluding that they are evenly matched, relative to our main criteria of adequacy. I offer tentative reasons to nevertheless favour the issue-based theory. (shrink)

Recent work in the philosophy of language attempts to elucidate the elusive notion of aboutness. A natural question concerning such a project has to do with its motivation: why is the notion of aboutness important? Stephen Yablo offers an interesting answer: taking into consideration not only the conditions under which a sentence is true, but also what a sentence is about opens the door to a new style of criticism of certain philosophical analyses. We might criticize the analysis (...) of a given notion not because it fails to assign the right truth conditions to a class of sentences, but because it characterizes those sentences as being about something they are not about. In this paper, I apply Yablo’s suggestion to a case study. I consider meta-fictionalism, the view that the content of a mathematical claim S is ‘according to standard mathematics, S’. I argue, following Woodward, that, on certain assumptions, meta-fictionalism assigns the right truth-conditions to typical assertoric utterances of mathematical statements. However, I also argue that meta-fictionalism assigns the wrong aboutness conditions to typical assertoric utterances of mathematical statements. (shrink)

The following Principle of Substitutivity holds for the former, but not for the latter sentence: (PS) The truth value of (the proposition expressed by) a sentence that contains an occurrence of t1 remains constant when t2 is substituted for t1, provided that t1 and t2 are codesignative singular terms. It is an undeniable fact that different sentences behave differently when it comes to which substitutions preserve their truth value. What is curious is that this fact has been presented by the (...) philosophical tradition as a puzzle. To be more precise, what is supposed to be puzzling is the breakdown of PS in some sentences. Meanwhile, it is assumed that everything is as it should be, that nothing needs to be explained when we observe that the substitution of 'the number of planets' for 'nine' in 'nine is greater than seven' guarantees the preservation of truth value, in spite of the fact that the subject matter of the former sentence and the subject matter of 'the number of planets is greater than seven' are radically different. The former sentence expresses a claim about numbers and their relationships, whereas the latter sentence makes an assertion about our solar system. (shrink)

In this chapter, I argue that genuinely abstract images do not depict but have aboutness, nevertheless. All images have aboutness in virtue of the visual configurations on their surfaces: it is through those configurations that they can convey something – they can mean something, represent something, express something, and so on. On the one hand, in depictive images, the visual configurations on the images’ surfaces depict visible objects while abstracting completely from some of their visual proper- ties. In (...) Giovanni Bellini’s Portrait of Doge Leonardo Loredan (1501), for instance, the visual configurations on the pictorial surface depict Doge Loredan’s head and torso, as seen frontally. The image, however, com- pletely abstracts from, e.g., Doge Loredan’s legs, nape, and back. On the other hand, as I shall argue, when the visual configurations on a two- dimensional surface do not depict anything at all but have aboutness in ways other than the depictive, that two-dimensional surface is a genu- inely abstract image. As I shall show, all genuinely abstract images entirely abstain from depicting but can nevertheless abstract in different measures from the visual properties of objects. The first step for an account of genuinely abstract images is to distin- guish accurately between depictive images and genuinely abstract ones. For this, one needs an account of depiction – this is provided in the first section of this chapter. In the second section, different kinds of depictive images are singled out: this facilitates focusing on images that qualify as genuinely abstract. In the third section, four ways in which genuinely abstract images have aboutness are discussed: conventionality, indexicality, exemplifica- tion, and expressivity. The fourth section concludes with some general observations on the peculiarities of genuinely abstract images. (shrink)

A reply to Fine’s critique of Aboutness. Fine contrasts two notions of truthmaker, and more generally two notions of “state.” One is algebraic; states are sui generis entities grasped primarily through the conditions they satisfy. The other uses set theory; states are sets of worlds, or, perhaps, collections of such sets. I try to defend the second notion and question some seeming advantages of the first.

I attempt to show that when someone is, E.G., Angry about something, The events or states that conjointly are causing him to be angry conform to a certain structure, And that from the causal structure underlying his anger it is possible to 'read out' what he is angry about. In this respect, And even in some of the details of the structure, My analysis of being angry about something resembles the belief-Want analysis of intentional action. The chief elements of the (...) causal structure I describe are a belief and an attitude so related in content as to constitute either a wish-Frustration (in the case of negative emotions) or a wish-Satisfaction (in the case of positive emotions). The analysis makes otiose, In those cases for which it is a correct analysis, The mysterious non-Causal relation between an emotion and its 'object' which is invoked by the majority of philosophers now writing on emotions.

A discussion of Imogen Dickie's book "Fixing Reference.".

The rationale, scientific necessity, and character of intentionality ascriptions (assertions that attribute beliefs, expectations, wishes and such to certain systems) remain unresolved issues in the philosophy of mind and psychology. Foxall's proposed resolution (2007), which he calls "Intentional Behaviorism" (IB), is that intentionality ascriptions should be tied to the experimental analysis of behavior, nervous systems, and evolutionary considerations. Foxall's tone of scientific pluralism and attention to academic philosophy and psychology are steps in the right direction. However, I remain skeptical about (...) IB's adequacy as a philosophical underpinning of psychology. My skepticism stems from IB's a-ontological character (which ignores the nature of intentionality, a major issue in psychology), pragmatist inclination (which invites relativism), and adoption of the linguistic view of intentionality, where intensionality is the defining criterion of intentionality. The linguistic view forces us either to restrict intentionality to humans, a deal-breaker for animal cognition psychologists, of to talk of mental language, a deal-breaker for operant psychologists. Also, an emphasis on extensionality, which is about logical validity and not soundness, fails to capture the emphasis of scientific psychology on evidence as a rationality criterion. Finally, if IB presupposes or entails linguistic anti-nativism, it is unlikely to appeal to evolutionary psychologists. IB would thus be better off by abandoning the linguistic view of intentionality. (shrink)

In his theory of truthmaker content, Kit Fine has provided many insights concerning the relation of aboutness, allowing us to understand why a unique subject matter can be associated to a sentence, what is the relation between the subject matter of a sentence and its truth conditions, and why necessary sentences can be distinguished with respect to what they are about. The aim of this chapter is to consider these insights critically, compare them to the notion of subject matter (...) developed by Lewis, and put forward a unified account giving us the resources to overcome some of their limits. The resulting theory characterizes the relation of aboutness by combining in a consistent framework Lewis’s intuition on how sentences are related to the questions they possibly answer with Fine’s intuition on how sentences are related to their truthmakers.

In 'Aboutness' (MIT Press 2014), Yablo argues for the importance of the notions of partial content and of partial truth. This paper argues that those notions are involved in a much greater range of entities than acknowledged by Yablo. The paper also argues that some of those entities involve a notion of partial satisfaction as well as partial existence (and partial validity).

Metasemantics is the metaphysics of semantic endowment: it asks how expressions become endowed with their semantic significance. Assuming that semantics is of the usual truth-conditional sort, metasemantics asks after the determinants of expressions’ distinctive contributions to truth-conditions. There are two widely divergent general approaches to the metasemantic project. Some theories – “productivist” ones such as causal theories or intention-based theories – emphasize conditions of production or employment of the items semantically endowed. Other metasemantic theories – “interpretationist” ones – emphasize conditions (...) of interpretive consumption or reception of such items. The book aims to articulate a set of considerations that favour metasemantic productivism over metasemantic interpretationism, to reconcile a general productivist metasemantic approach with contemporary truth-conditional semantics, and to apply the approach to more specialized case studies in the philosophy of language broadly construed. Finally, a major concern in contemporary philosophy of language after Quine is semantic indeterminacy, the worry that there is no fact of the matter as to the semantic significance of our words. The book articulates a distinctly metasemantic strategy to counter the worry. It is shown how the present approach delivers a more successful response to semantic indeterminacy than extant alternatives, a response that emphasizes the priority of reference over truth, which is both intuitively compelling and theoretically motivated.

This paper develops a theory of propositional identity which distinguishes necessarily equivalent propositions that differ in subject-matter. Rather than forming a Boolean lattice as in extensional and intensional semantic theories, the space of propositions forms a non-interlaced bilattice. After motivating a departure from tradition by way of a number of plausible principles for subject-matter, I will provide a Finean state semantics for a novel theory of propositions, presenting arguments against the convexity and nonvacuity constraints which Fine (2016, 2017a,b) introduces. I (...) will then move to compare the resulting logic of propositional identity (PI) with Correia’s (2016) logic of generalised identity (GI), as well as the first degree fragment of Angell’s (1989) logic of analytic containment (AC). The paper concludes by extending PI to include axioms and rules for a subject-matter operator, providing a much broader theory of subject-matter than the principles with which I will begin. (shrink)

The topic of this paper is the question of in virtue of what first-person thoughts are about what they are about. I focus on a dilemma arising from this question. On the one hand, approaches to answering this question that promise to be satisfying seem doomed to be inconsistent with the seeming truism that first-person thought is always about the thinker of the thought. But on the other hand, ensuring consistency with that truism seems doomed to make any answer to (...) the question unsatisfying. Contrary to a careful and enticing recent effort to both sharpen and escape this dilemma by Daniel Morgan, I will argue that the dilemma remains pressing both for broadly epistemic and broadly causal-acquaintance-based accounts of the aboutness of first-person thought.

A lightning fast summary of Yablo, Aboutness, cutting many corners in the interests of brevity. The emphasis is on “ways.” Substituting “ways for S to be true” in for “worlds in which S is true” improves a number of philosophical explanations. The subject matter of S is identified with S’s ways of holding in a world, or failing, as the case may be. S contains T iff T is implied by S, and T’s ways of being true are implied (...) by ways for S to be true ; this kind of way-implication is the same as subject matter inclusion. S’s surplus content over T is explained as that portion of the content of S that is not about whether T. Subject matter is cast throughout as a full partner in meaning. (shrink)

Pretheoretically, ‘all believers are immortal’ is about all believers, but B is not about any unbeliever. Similarly, ‘all mortals are unbelievers’ is not about any immortal, but M is about all mortals. But B and M are logically equivalent universal generalizations, so arguably they are about exactly the same objects; by, they are about those mortals who are unbelievers, contradicting. If one responds by giving up, is there still a sense in which B treats unbelievers differently from believers? I argue (...) that there is. B is uninformative about unbelievers but informative about believers, in the following sense: for any object o, the information that B provides only about o—namely, ‘o is a believer only if o is immortal’—is entailed by ‘o is an unbeliever’ but not by ‘o is a believer’.

Holmes exists is false. How can this be, when there is no one for the sentence to misdescribe? Part of the answer is that a sentence’s topic depends on context. The king of France is bald, normally unevaluable, is false qua description of the bald people. Likewise Holmes exists is false qua description of the things that exist; it misdescribes those things as having Holmes among them. This does not explain, though, how Holmes does not exist differs in cognitive content (...) from, say, Vulcan does not exist. Our answer builds on an observation of Kripke’s: even if Holmes exists, he is not in this room, for we were all born too late. (shrink)

This book argues that words and thoughts are typically about whatever they are about necessarily rather than contingently. The argument proceeds by articulating a requisite modal background and then bringing this background to bear on cognitive matters, notably the intentionality of cognitive episodes and states. The modal picture that emerges from the first two chapters is a strongly particularist one whereby possibilities reduce to possibilities for particular things (or pluralities thereof) where the latter are determined by the natures of the (...) particular things (or pluralities) involved. The next three chapters are devoted to the aboutness of referring terms in language and thought. The approach espoused is, again, strongly particularist in allotting explanatory priority to cognitive episodes and states regarding particular things (aka de re attitudes). (shrink)

Semantics, Metasemantics, Aboutness. By Simchen Ori.

The aim of this paper is to reinforce anti-physicalism by extending the hard problem to a specific kind of intentional states. For reaching this target, I investigate the mental content of the new intentional states of Jackson’s Mary. I proceed in the following way: I start analyzing the knowledge argument, which highlights the hard problem tied to phenomenal consciousness. In a second step, I investigate a powerful physicalist reply to this argument: the phenomenal concept strategy. In a third step, I (...) propose a constitutional account of phenomenal concepts that captures the Mary scenario adequately, but implies anti-physicalist referents. In a last step, I point at the ramifications constitutional phenomenal concepts have on the constitution of Mary’s new intentional states. Therefore, by focusing the attention on phenomenal concepts, the so-called hard problem of consciousness will be carried over to the alleged easy problem of intentional states as well. (shrink)

Many have taken Sellars’s critique of empiricism in “Empiricism and the Philosophy of Mind” (EPM) to be aimed at his teacher C. I. Lewis. But if so, why do the famous arguments of its opening sections carry so little force against Lewis’s views? Understandably, some respond by denying that Lewis’s epistemology is among the positions targeted by Sellars. But this is incorrect. Indeed, Sellars had earlier offered more trenchant (if already familiar) critiques of Lewis’s epistemology. What is original about EPM (...) is that it criticizes empiricist positions like Lewis’s not because of their foundationalism, but because of their psychologism about meaning. Since psychologism turns out to be unacceptable by Lewis’s own lights, EPM has a compelling (if implicit) critique of Lewis to offer after all, one that strikes at the heart of his philosophical system.

This paper concerns Yablo’s theory of asserted content as it is developed in his new book Aboutness. Yablo’s central idea is that in order to specify the asserted content of a sentence, we have to subtract those parts of its full semantic content that concern irrelevant subject matters. The paper argues that it is doubtful whether Yablo’s account successfully deals with its most basic envisaged application: to account for a difference of apparent truth value in cases of ordinary presupposition (...) failure. In addition, some doubts are raised concerning the success of the extension of Yablo’s account to fictional talk, the informativeness of identity statements, and ontological commitments of number talk.

The author suggests that educational philosophy should benefit from addressing questions traditionally asked within discourse in the philosophy of mind, namely: the relation between the mind and world and the problems of intentionality , meaning, and representation. Peirce's semiotics and his category of creative abduction provide a novel conceptual framework for exploring these questions. A model of reasoning and learning, based on Peirce's triadic logic of relations, is analysed. This model, it is argued, is fruitful for overcoming the paradox of (...) new knowledge that was first debated by Socrates in his dialogue with Meno. (shrink)

constructive empiricism asserts that it is not for science to reach a verdict on whether a theory is true or false, if the theory is about unobservable entities; science's only interest here, says Van Fraassen, is to discover whether the theory is ‘empirically adequate’. However, if a theory is soley about observables, empirical adequacy and truth are said to ‘coincide’, here discovering the theory's truth value is an appropriate scientific goal. Constructive empiricism thus rests an epistemological thesis on a semantical (...) distinction. This paper critically examines the notion of aboutness and its epistemological significance. * I am grateful to members of my philosophy of science seminar during Spring, 1983 for useful discussion and to the two anonymous referees of this journal for providing helpful suggestions.

Over the last twenty years, many attempts have been made to discard the intentionality possessed by prima facie contentful mental states (intentional acts; atttudes, in Russell’s terms), where this is understood as the special, mental-orsemantic, quality of being ‘directed’ upon something. This has also involved dispensing with special ‘aboutness’-properties like being about O, which stand to intentionality as species to genus. These naturalistic strategies have been oriented in two ontologically different ways, conservative or revolutionary. The first has been pursued (...) either reductionalistically or non-reductionalistically. The reductionist is a radical naturalist, who believes that intentionality exists, but it is a quality in nature investigated by the empirical sciences. The non-reductionist, vice versa, is a moderate naturalist, for whom intentionality merely supervenes on a non- mental-or-semantic quality. The revolutionary option, on the other hand, is eliminativistic. The position is one of extremist naturalism, for which intentionality exists no more than phlogiston or sunsets. In what follows, I first criticize the reductionists’ position. By relying on the two main features of intentionality, namely that of being ‘directed upon’ an object which may not exist and that of being an internal relation between the relevant attitude and such an object, I try to show why reduction of any kind - conceptual, metaphysical or nomological - cannot work. Secondly, the second features then allows me to show why moderate naturalism is also doomed to fail. Finally, I argue against eliminativism by showing that, qua genuine property, intentionality is indispensable for the individuation of attitudes. It thus turns out that attitudes endowed with intentionality as well as with the related ‘aboutness’-property are individuated in terms of non-natural properties. This is to say, beliefs as well as all other prima facie contentful mental states are effectively contentful insofar as they possess a particular ‘aboutness’-property.. (shrink)

Competent speakers of natural languages can borrow reference from one another. You can arrange for your utterances of ‘Kirksville’ to refer to the same thing as my utterances of ‘Kirksville’. We can then talk about the same thing when we discuss Kirksville. In cases like this, you borrow “ aboutness ” from me by borrowing reference. Now suppose I wish to initiate a line of reasoning applicable to any prime number. I might signal my intention by saying, “Let p (...) be any prime.” In this context, I will be using the term ‘p’ to reason about the primes. Although ‘p’ helps me secure the aboutness of my discourse, it may seem wrong to say that ‘p’ refers to anything. Be that as it may, this paper explores what mathematical discourse would be like if mathematicians were able to borrow freely from one another not just the reference of terms that clearly refer, but, more generally, the sort of aboutness present in a line of reasoning leading up to a universal generalization. The paper also gives reasons for believing that aboutness of this sort really is freely transferable. A key implication will be that the concept “set of natural numbers” suffers from no mathematically significant indeterminacy that can be coherently discussed. (shrink)

Trust may have many different informal definitions. In this work, formal definitions are proposed in Modal Logic in order to have clear rules for reasoning about trust. We start from trust in some properties of an information source, like sincerity, competence or vigilance, about a given proposition. Then, this definition is extended to trust about all the propositions which are about a given topic. A further extension is about all the propositions which inform about a given individual. Specific logics are (...) presented for reasoning about the fact that a given proposition is about a given topic and for reasoning about the fact that a proposition informs about a given individual. At the end, we give a brief extension to qualitative graded trust. (shrink)

I follow Giordani in distinguishing between a situational and informational conception of subject-matter and consider some of the different ways in which it might be explained within both an intensional and an hyperintensional account of propositional identity.

Anotace Following Carnap's Principle of Subject Matter, Pavel Tichý proposed a methodological principle I call the "Denotational Principle of Aboutness". It says that expressions are about their denotata. Denotata are modelled as possible world intensions or (common) extensions. Nearly the same principle was recently defended by Marie Duží and Pavel Materna under the name the "Parmenides Principle". However, Duží and Materna did not react to Tichý's late proposal which I call the "Constructional Principle of Aboutness". It says that (...) the subject matter of expressions consists not in their denotata but their meanings. The meanings are explicated by Tichý, and also by Duží and Materna, as so-called constructions; constructions are complex entities akin to algorithms, they construct intensions or extensions. In this paper, I argue in favour of the Constructional Principle of Aboutness. I show that there are not only single arguments, but whole net of methodological principles which support it. This is why the topic largely transcends the debate among Tichý's followers. (shrink)
