In Constructing the World, Chalmers seeks to articulate and defend an important epistemic accessibility thesis, the Scrutability of Truth, which is crucial to Chalmers’ rationalist approach to meaning and modality. Chapters 3 and 4 of the book are devoted to persuading us that the move from weaker to stronger forms of Scrutability is intuitively plausible. In these comments, I want to question this move. The plausibility of strong forms of Scrutability hinges on controversial views about epistemic norms (...) for answering ‘what is x?’ questions that semantic externalists have good reason to reject.

Chalmers has argued that Bayesianism supports the existence of a priori truths, since it entails that scrutability conditionals are not rationally revisable. However, as we argue, Chalmers's arguments leave open that every proposition is rationally deniable, which would be devastating for large parts of his philosophical program. We suggest that Chalmers should appeal to well-known convergence theorems to argue that ideally rational subjects converge on the truth of scrutability conditionals. However, our discussion reveals that showing that these theorems (...) apply in effect requires assuming scrutability. Consequently, Bayesianism doesn't conflict with Chalmers's scrutability framework, but it doesn't support it, either. (shrink)

In his recent book Constructing the World, David Chalmers defends A Priori Scrutability, the thesis that there is a compact class of truths such that for any truth p, a Laplacian intellect could know a priori that if the truths in that class hold, then p. In this paper, I develop an objection to Chalmers’ thesis that focuses on his treatment of a so-called that’s-all truth. My objection draws on Theodore Sider’s discussion of border-sensitive properties, and also on the (...) causal phenomenon of double prevention. (shrink)

What is the aim of philosophy? There may be too many philosophical branches, traditions, practices, and programs to admit of a single overarching aim. Here I focus on a fairly traditional philosophical project that has recently received increasingly sophisticated articulation, especially by Frank Jackson (1998) and David Chalmers (2012). In §1, I present the project and suggest that it is usefully thought of as ‘total axiomatics’: the project of attempting to axiomatize the total theory of the world. In §2, I (...) raise a problem for the project that I call the ‘problem of multiple axiomatizations.’ I consider some initially alluring but ultimately unpromising approaches to this problem in §3. In §4, I defend a surprising approach to the problem, according to which competing axiomatizations of the total theory of the world are effectively evaluated for their aesthetic virtues. (shrink)

According to the scrutability argument against physicalism, an a priori gap between the physical and conscious experience entails a lack of necessitation and the falsity of physicalism. This paper investigates the crucial premise of the scrutability argument: the inference from an a priori gap to a lack of necessitation. This premise gets its support from modal rationalism, according to which there are important, potentially constitutive, connections between a priori justification and metaphysical modality. I argue against the strong form (...) of modal rationalism that underwrites the scrutability argument and suggest a more moderate rationalist view. I offer a novel demonstrative reply to the scrutability argument, according to which demonstratives play a vital role in the generation of meaning for our representations of conscious experience. This connection between conscious experience and demonstratives, rather than a metaphysical gap generated by the truth of dualism, is the source of the epistemic gap between consciousness and the physical.

The view that species are individuals, as developed by Ghiselinand Hull, has been touted as explaining the role of type specimens intaxonomy. The kinship of this explanation with the Kripke-Putnam theoryof names has long been recognized. In light of this kinship, however,Hull's account of type specimens can be seen to entail two relatedinscrutability problems – unreasonable limits placed on the natureand extent of biological knowledge. An appreciation for these problemsinvites us to consider the proper relation between metaphysical andepistemological inquires in (...) the philosophy of science. (shrink)

I discuss David Chalmers’ “scrutability thesis,” roughly that a Laplacean intellect could know every truth about the universe from a “compact class” of basic truths. It is argued that despite Chalmers’ remarks to the contrary, the thesis is problematic owing to quantum indeterminacy. Chalmers attempts to “frontload” various principles into the compact class to help out. But though frontloading may succeed in principle, Chalmers does not frontload enough to avoid the problem.

Inspired by Rudolf Carnap's Der Logische Aufbau Der Welt, David J. Chalmers argues that the world can be constructed from a few basic elements. He develops a scrutability thesis saying that all truths about the world can be derived from basic truths and ideal reasoning. This thesis leads to many philosophical consequences: a broadly Fregean approach to meaning, an internalist approach to the contents of thought, and a reply to W. V. Quine's arguments against the analytic and the a (...) priori. Chalmers also uses scrutability to analyze the unity of science, to defend a conceptual approach to metaphysics, and to mount a structuralist response to skepticism. Based on the 2010 John Locke lectures, Constructing the World opens up debate on central philosophical issues involving language, consciousness, knowledge, and reality. This major work by a leading philosopher will appeal to philosophers in all areas. This entry contains uncorrected proofs of front matter, chapter 1, and first excursus. (shrink)

A critical notice of David J. Chalmers, Constructing the World (Oxford University Press,2012).

PREFACE: - BY his theory of relativity Albert Einstein has provoked a revolution of thought in physical science. The achievement consists essentially in this Einstein has succeeded in separating far more completely than hitherto the share of the observer and the share of external nature in the things we see happen. The perception of an object by an observer depends on his own situation and circumstances for example, distance will make it appear smaller and dimmer. We make allowance for this (...) almost unconsciously in interpreting what we see. But it now appears that the allowance made for the motion of the observer has hitherto been too crude a fact overlooked because in practice all observers share nearly the same motion, that of the earth. Physical space and time are found to be closely bound up with this motion of the observer and only an amorphous combination of the two is left inherent in the external world. When space and time are relegated to their proper source the observer the world of nature which remains appears strangely unfamiliar but it is in reality simplified, and the underlying unity of the principal phenomena is now clearly revealed. The deductions from this new outlook have, with one doubtful exception, been confirmed when tested by experiment. It is my aim to give an account of this work without intro ducing anything very technical in the way of mathematics, physics, or philosophy. The new view of space and time, so opposed to our habits of thought, must in any case demand unusual mental exercise. The results appear strange and the incongruity is not without a humorous side. For the first nine chapters the task is one of interpreting a clear-cut theory, accepted in all its essentials by a large and growing school of physicists although perhaps not everyone would accept the authors views of its meaning. Chapters x and xi deal with very recent advances, with regard to which opinion is more fluid. As for the last chapter, containing the authors specula tions on the meaning of nature, since it touches on the rudiments of a philosophical system, it is perhaps too sanguine to hope that it can ever be other than controversial. A non-mathematical presentation has necessary limitations and the reader who wishes to learn how certain exact result follow from Einsteins, or even Newtons, law of gravitation m bound to seek the reasons in a mathematical treatise. But thj limitation of range is perhaps less serious than the limitation of intrinsic truth. There is a relativity of truth, as there is a relativity of space. For is and IS-NOT though with Rule and Line And UP-AND-DOWK without, I could define, Alas It is not so simple. We abstract from the phenomena that which is peculiar to the position and motion of the observer but can we abstract that which is peculiar to the limited imagina tion of the human brain We think we can, but only in the symbolism of mathematics. As the language of a poet rings with a truth that eludes the clumsy explanations of his commentators, so the geometry of relativity in its perfect harmony expresses a truth of form and type in nature, which my bowdlerised version misses. But the mind is not content to leave scientific Truth in a dry husk of mathematical symbols, and demands that it shall be alloyed with familiar images. The mathematician, who handles x so lightly, may fairly be asked to state, not indeed the in scrutable meaning of a in nature, but the meaning which x conveys to him. Although primarily designed for readers without technical knowledge of the subject, it is hoped that the book may also appeal to those who have gone into the subject more deeply. A few notes have been added in the Appendix mainly to bridge the gap between this and more mathematical treatises, and to indicate the points of contact between the argument in the text and the parallel analytical investigation. It is impossible adequately to express my debt to con temporary literature and discussion... (shrink)

The problem of intentional inexistence arises because the following (alleged) intuitions are mutually conflicting: it seems that sometimes we think about things that do not exist; it seems that intentionality is a relation between a thinker and what such a thinker thinks about; it seems that relations entail the existence of what they relate. In this paper, I argue for what I call a radical relationist solution. First, I contend that the extant arguments for the view that relations entail the (...) existence of their relata are wanting. In this regard, I defend a kind of pluralism about relations according to which more than one kind of relation involves non-existents. Second, I contend that there are reasons to maintain that all thoughts are relations between thinkers and the things they are about. More accurately, I contend that the radical relationist solution is to be preferred to both the intentional content solution (as developed by Crane) and the adverbial property solution (as developed by Kriegel). Finally, I argue that once the distinction between thinking “X” and thinking about X has been drawn, the radical relationist solution can handle issues like ontological commitment, substitutivity failure, scrutability, and non-specificity.

Russellian physicalism is a view on the nature of consciousness which promises to satisfy the demands of both traditional physicalists and non-physicalists. It does so by identifying subjective experience with physically acceptable categorical properties underlying structural and dispositional properties described by science. Though promising, the view faces at least two serious challenges: (i) it has been argued that science deals in both categorical and non-categorical properties, which would undercut the motivation behind Russellian physicalism, and (ii) it has been argued that (...) only nonphysicalist Russellian views—like panpsychism—are useful when it comes to explaining consciousness. I address these criticisms, arguing that there is no viable reason for maintaining that science deals in categorical properties of the sort which a Russellian physicalist is interested in, and that features of fully-physical categorical properties can be described which provide useful explanations for various essential features of subjective experience. These projects are connected: it turns out that when the explanatory relevance of Russellian physicalism is explained in detail, constraints are put the sort of categorical properties that Russellian physicalists can say are left out of science. Specifically, Russellian physicalists are forced to subscribe to the view that science leaves out any categorical properties whatsoever, as opposed to the view that some scientifically scrutable properties are categorical, but not the ones which Russellian physicalists are interested in. I hope that by addressing these criticisms of Russellian physicalism, and drawing logical connections between the responses, further appeal is added to a promising, but so far relatively unexplored, view.

This is a review of David Chalmers's /Constructing the World/. The short, short version: there are issues, but you should definitely read the book.

According to a radical account of quantum metaphysics that I label ‘high-dimensionalism’, ordinary objects are the ‘shadows’ of high-dimensional fundamental ontology. Critics—especially Maudlin —allege that high-dimensionalism cannot provide a satisfactory explanation of the manifest image. In this paper, I examine the two main ideas behind these criticisms: that high-dimensionalist connections between fundamental and non-fundamental are 1) inscrutable, and 2) arbitrary. In response to the first, I argue that there is no metaphysically significant contrast regarding the scrutability of low- and (...) high-dimensionalist connections. In response to the second, I argue that the arbitrariness of high-dimensionalist connections has been overstated, and what arbitrariness there is afflicts low-dimensionalist connections too. Thus, the debate should not be focused on whether high-dimensionalism can provide a satisfactory explanation of the manifest image—as it has been in recent literature—but rather on the broader question of whether there is good all-things-considered reason to prefer low-dimensionalist theories.

Maybe the most important argument in David Chalmers’s monumental book Constructing the World is the one he calls the ‘Frontloading Argument’, which is used in Chapter 4 to argue for the book’s central thesis, A Priori Scrutability. And, at first blush, the Frontloading Argument looks very strong. I argue here, however, that it is incapable of securing the conclusion it is meant to establish.

This paper concerns top-down approaches in machine ethics. It is divided into three main parts. First, I briefly describe top-down design approaches, and in doing so I make clear what those approaches are committed to and what they involve when it comes to training an AI to behave ethically. In the second part, I formulate two underappreciated motivations for endorsing them, one relating to predictability of machine behavior and the other relating to scrutability of machine decision-making. Finally, I present (...) three major worries about such approaches, and I attempt to show that advocates of top-down approaches have some plausible avenues of response. I focus most of my attention on what I call the ‘technical manual objection’ to top-down approaches, inspired by the work of Annas (2004). In short, the idea is that top-down approaches treat ethical decision-making as being merely a matter of following some ethical instructions in the same way that one might follow some set of instructions contained in a technical manual (e.g., computer manual), and this invites sensible skepticism about the ethical wisdom of machines that have been trained on those approaches. I respond by claiming that the objection is successful only if it is understood as targeting machines that have certain kinds of goals, and it should not compel us to totally abandon top-down approaches. Such approaches could still be reasonably employed to design ethical AI that operate in contexts that include fairly noncontroversial answers to ethical questions. In fact, we should prefer top-down approaches when it comes to those types of context, or so I argue, due to the advantages I claim for them. (shrink)

Cappelen proposes a radically externalist framework for conceptual engineering. This approach embraces the following two theses. Firstly, the mechanisms that underlie conceptual engineering are inscrutable: they are too complex, unstable and non-systematic for us to grasp. Secondly, the process of conceptual engineering is largely beyond our control. One might think that these two theses are peculiar to the Austerity Framework, or to metasemantic externalism more generally. However, Cappelen argues that there is no reason to think that internalism avoids either commitment. (...) Cappelen argues that to do so she must provide arguments for 3 claims: there are inner states that are scrutable and within our control; concepts supervene on these inner states; and the determination relation from supervenience base to content is itself scrutable and within our control. In this paper, I argue that internalist conceptual role theories of content can meet Cappelen’s challenge. (shrink)

This paper presents a new response to the colour similarity argument, an argument that many people take to pose the greatest threat to colour physicalism. The colour similarity argument assumes that if colour physicalism is true, then colour similarities should be scrutable under standard physical descriptions of surface reflectance properties such as their spectral reflectance curves. Given this assumption, our evident failure to find such similarities at the reducing level seemingly proves fatal to colour physicalism. I argue that we should (...) dispense with this assumption, and thus endorse the inscrutability of colour similarity. This strategy is inspired by parallels between the colour similarity argument and the explanatory gap between mind and body made vivid by Jackson’s (1986) knowledge argument, and in particular by type-B physicalist responses to that argument. This inscrutability response is further motivated by cases in chemistry and biochemistry in which analogous scrutability theses fail to hold. Along the way, I present a challenge to standard formulations of the colour similarity argument based on the extreme context sensitivity of the similarity relation. Most presentations of the argument fail to control for such contextual variation, which raises the distinct possibility that the argument equivocates on the similarity relation across its premises. Although ultimately inconclusive, this context challenge forces a significant reformulation of the colour similarity argument, and highlights the need for much greater care in handling claims about colour similarity.

The article tries to show, from the phenomenological posi­tion, that it must be possible to reflect on so called pre-linguistic experience. The argumenta­tion is based on a disputation with a symptomatic example used by Wittgen-stein to substan­tiate his language games theory. The analysis of the example at­tempts to indicate that the language games theory, which has to justify the rejection of the existence of pre-linguistic experience, meets with discre-pancies and difficulties which limit the range of this theory to a certain (...) extent. Because it presupposes the existence of „private“, experiential sphere in which – even before language and verbali­zation enter the game – the struc­turing of the world, identifi­cation of things and an elementary under-stan­ding of these processes must be realized. It seems that the dis-cussion on this topic is not only a spe­cific polemic over one problem that can be found in Wittgenstein, but has wider implications because the language games concept in the form of various „discourses“, „vocabularies“ or „cultures“ has found great favour in contemporary postmo­dern philo­sophy. On its basis postmodern philosophy very radi­cally crosses out the world, profanes its rational, objec­tive description and calls for free variation of different interpretations – their legitimacy is authenti­cated only by a consensus of their users. In this dispute, phe­nome­nology does not declare that there is a single true description of the world and that it is possible to find a reliable criterion for its definite legiti­mization. It does, however, draw on the fact that so called pre-linguistic expe­rience does not succumb to the variability of langu­age games and the interests of its users, but that it more and more cle­arly reflects the unitary and scru­table style of showing the real, ob­jectively given world even though this al­ways happens in se­emingly impalpable subjective acts.

Psychology’s emphasis on empirical investigation has long benefited from conceptual developments taking place in its intellectual community, but also from cognate areas in Philosophy. This paper explores the implications for empirical psychology of a recent conceptual proposal advanced within the philosophy of perception by Bence Nanay. In particular, Nanay proposes that “pragmatic representations”, i.e., perceptual representations of the properties of objects necessary for the successful completion of actions, are the rightful target for a success semantics. A success semantics is, roughly (...) speaking, a theory of contents according to which the truth conditions of representations are to be identified with the success conditions of actions guided by the representations. The problem arises for Nanay’s proposal in that the empirical scrutiny of the contents of a pragmatic representation requires that one first ascertains their content, but it is not at all clear whether this could possibly be done given the non-linguistic character of pragmatic representations on the one hand, and the linguistic character of third-personal verbal data acquired through an heterophenomenological methodology on the other. This and other concerns raise worries about the empirical scrutability of Nanay’s proposal. (shrink)

The idea of a folk theory has played many important roles in much recent philosophy. To do the work they are designed for, they need to be both internal features of agents who possess them, and yet scrutable without the full resources of empirical cognitive science. The worry for the theorist of folk theories, is that only one of these desiderata is met in each plausible conception of a folk theory. This paper outlines a third conception that meets them both.1.

The principle of mass additivity states that the mass of a composite object is the sum of the masses of its elementary components. Mass additivity is true in Newtonian mechanics but false in special relativity. Physicists have explained why mass additivity is true in Newtonian mechanics by reducing it to Newton’s microphysical laws. This reductive explanation does not fit well with deducibility theories of reductive explanation such as the modern Nagelian theory of reduction, and the a priori entailment theory of (...) reduction that is prominent in the philosophy of mind. Nonetheless, I argue that a reconstruction of the explanation that incorporates distinctively philosophical concepts in fact fits both theories. I discuss the implications of this result for both theories and for the reductive explanation of consciousness. (shrink)

To begin to answer the question of whether every moral truth could be known by any one individual, this paper examines David Chalmers’ views on the scrutability of moral truths in Constructing the World. Chalmers deals with the question of the scrutability of moral truths ecumenically, claiming that moral truths are scrutable on all plausible metaethical views. I raise two objections to Chalmers’ approach. The first objection is that he confl ates the claim that moral truths are scrutable (...) from PQTI with the claim that moral truths are scrutable from nonmoral truths. The upshot of this objection is that Chalmers has not in fact shown the scrutability of moral truths from the scrutability base from which he proposed to do so, PQTI. The second objection concerns his handling of moral sensibility theory, which fails to take into account certain features of the emotions—features which generate what I term synchronic and diachronic emotional co-instantiation problems. The upshot of this objection is that we have good reason to deny that any one individual could ascertain all moral truths, if moral sensibility theory is true, no matter how idealized the emoter.

All else being equal, can granting the objective purport of moral experience support a presumption in favor of some form of moral objectivism? Don Loeb (2007) has argued that even if we grant that moral experience appears to present us with a realm of objective moral fact—something he denies we have reason to do in the first place—the objective purport of moral experience cannot by itself provide even prima facie support for moral objectivism. In this paper, I contend against Loeb (...) that granting the objective purport of ordinary moral experience is sufficient to support a defeasible presumption in favor of moral objectivism, and this by constituting non-explanatory, comparative confirmation that incrementally raises the prima facie likelihood that moral facts exist. More specifically, I appeal to a modest confirmation principle shared by Likelihoodists and Bayesieans - namely, the Weak Law of Likelihood - in an effort to show that (i) at a minimum, moral experience establishes a middling scrutable probability for a sufficient but not necessary condition of moral objectivism being true, and that (ii) this moderate probability in turn constitutes evidence that makes it prima facie more probable than not that some form of moral objectivism is true.

Metaphor, I argue, is a type of expression that is used to communicate information beyond that communicated by its literal meaning. I argue that the literal meaning of metaphors are essential. I attempt to account for metaphor in such a way as to retain the literal meaning, while also accounting for what is called the "metaphorical meaning" of metaphors. Secondly, I am concerned with the mechanisms in virtue of which we are able to distinguish the metaphorical from the literal. ;Chapter (...) I is a discussion of the problems that I will consider in the dissertation. These include distinguishing metaphorical from literal expressions, Donald Davidson's learnability and scrutability criteria, the exclusionary criteria, conversion and constancy theories of metaphor, and truth-values of metaphors. ;Chapter II critically examines Aristotle's, Max Black's, and Monroe C. Beardsley's intensional conversion theories. Here I argue that conversion theories are inadequate and unnecessary to account for metaphorical attributions. ;Chapter III critically examines extensional conversion theories of metaphor including Nelson Goodman's version. I discuss the difficulties that arise in postulating such reference conversions. I argue that this type of conversion theory is also unsuccessful and unnecessary. ;Chapter IV is a critical examination of four types of emotive theory of metaphor, one of which is Max Rieser's. These theories maintain, and I deny, that metaphors have an "emotive meaning" in addition to or instead of their literal meaning. I consider the shortcomings and consequences of emotive views, and argue that the postulation of emotive meanings is also misguided and unnecessary. ;Chapter V offers an alternative to conversion theories. Here I argue for a theory requiring no meaning or reference conversions. My view involves H. P. Grice's notions of conversational maxims and implicatures. I conclude that metaphors retain their literal meaning, partly in virtue of which they generate implicatures. I also conclude that our recognition of, and ability to distinguish, metaphors from literal expressions involves the violations of conversational maxims. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Confucian Rituals and the Technology of the Self:A Foucaultian InterpretationHahm ChaibongIntroductionModern political theory is "liberation" theory. Liberalism pivots on the idea of individual liberty, defined largely as freedom from government interference in private lives. All major versions of it, from the Lockian social-contract theory to the Rawlsian theory of justice, focus on protecting the rights of the individual. Marxism and other leftist political theories revolve around the notion of (...) recovering and liberating the original freedom of humanity that has been corrupted or otherwise twisted out of recognition by modern society and its institutions. Rousseau, Marx, and Freud all long for the "total revolution" that will free humanity from the decadence of modern society, capitalism, and even civilization itself.1 In marked contrast to modern Western political theories, Confucianism emphasizes harmony in interpersonal relationships and affirms the role of the family, the community, and the state as essential components of a just and humane society. Civilization is considered both the means and the end of human flourishing, not something to be limited, abolished, or otherwise overcome. In terms of its "micro-theory," Confucianism emphasizes self-discipline, ritual propriety, and moral uprightness, not individual freedom and liberation.At first sight, the disciplined, proper, and moralistic Confucian might seem a far cry from the free, independent, and spontaneous individual of liberalism. The strong emphasis placed on human-relatedness and social harmony, enforced by elaborate codes of ritual conduct, would seem to encourage "rational adjustment to the world," not revolutionary incitement to change it. Confucianism is thus often regarded as the premodern political theory par excellence by modern political theorists. From the May Fourth Movement through the Great Cultural Revolution to the Asian Values debate, Confucianism has always stood as the symbol of feudalism and as the single greatest obstacle to modernity, hindering the development of a scientific outlook, class consciousness, and liberal democratic values.In what follows, however, I argue that the Confucian practices of self-discipline and ritual propriety are quite suitable for a democratic society. Indeed, not only is Confucianism suitable for democracy, but it also fills an important lacuna in modern democratic theory. In a liberal-democratic society, citizens are given ever more freedom to exercise their rights. However, theories of negative freedom and other "primacy-of-rights" theories have privileged individual liberty and rights to such an extent that citizens in a modern democracy have little basis for mutual consultation, deliberation, and agreement. As a result, there is very little in liberal theory, or in [End Page 315] theories of the left, for that matter, that deals with concrete ways in which freedom can be exercised. Confucian theories and practices of self-discipline and ritual propriety can fill this gap in liberal theory.In making this point, I enlist the help of Michel Foucault. Foucault's investigations of ancient Greek and Roman technologies of the self in his later works show that the practices of self-cultivation, self-discipline, and ritual conduct do not necessarily inhibit freedom.2 In fact, such practices are indispensable for the proper practice of freedom. Moreover, Foucault's now-famous investigation of the logic of power, discipline, truth, and knowledge provides a profound insight into the nature of freedom and its practice that is not to be found in currently dominant liberal theories. It provides an important antidote to the common misconception that selfdiscipline and ritual propriety are contrary to individual freedom. Foucault thus provides us with a new perspective from which to investigate and affirm the democratic potential of Confucianism.The Scrutable Body and LiIn the Western philosophical tradition, the metaphysical, the transcendental, or the purely rational has always been the "real." The Platonic eidos, the Christian soul, the Cartesian cogito, and the Kantian noumena all emphasize the priority and the primacy of the metaphysical over the physical as the repository of truth, beauty, and reality. The physical body, on the other hand, has been viewed as the corrupted shadow of the ideal form, the prison of the soul, a mere physical extension or a passing phenomenon. Modern psychology, Freudian or otherwise, emphasizes the conscious/unconscious as the realm that determines our being and character. In contrast... (shrink)

Universal reductionism—the sort of project pursued by Carnap in the Aufbau, Lewis in his campaign on behalf of Humean supervenience, Jackson in From Metaphysics to Ethics, and Chalmers in Constructing the World—aims to reduce everything to some specified base, more or less austere as it may be. In this paper, I identify two constraints that a promising strategy to argue for universal reductionism needs to satisfy: the exhaustion constraint and the chaining constraint. As a case study, I then consider Chalmers’ (...) Constructing the World, in which a priori implication, or “scrutability”, plays the role of reduction. Chalmers first divides up the total vocabulary of our language into different families, and then argues, for each family separately, that truths involving expressions in that family are scrutable from the putative base. He does not systematically address the question whether “cross-family sentences”—sentences involving expressions from more than one family—are scrutable. I shall argue that this lacuna cannot be filled, since scrutability does not allow for the exhaustion constraint and the chaining constraint to be jointly satisfied. I further suggest that Carnap’s account, in which definability plays the role of reduction, has better prospects of meeting these constraints. (shrink)

In this paper I discuss, on behalf of the materialist, a consideration against the modal or conceivability argument against materialism which was first voiced in the third lecture of Naming and Necessity. This consideration is based on intertheoretic identities, statements in which both terms flanking the identity sign are theoretical. I argue that the defender of the conceivability argument has trouble to account for the appearance of contingency in those types of necessary identities. In fact, intertheoretic identities pose a formidable (...) dilemma for the defender of the modal argument and actually force the antimaterialist to say more about the semantics of theoretical terms than is implicit in standard discussions of the argument. I myself consider several options in this regard, the upshot being, however, that none of the alternative semantics for theoretical terms available to the antimaterialist is good enough to achieve the twofold aim which her modal argument requires, namely, to account for the a posteriori necessity of identities of this sort and, at the same time, to preserve her antimaterialist argument. Finally, in the last part of the paper, I argue that my defense of materialism can withstand some worries coming from David Chalmers’ recent views on a priori scrutability. (shrink)

The Continuum Hypothesis seems to be a counterexample to David Chalmers’s A Priori Scrutability thesis, according to which there is a compact class of truths from which all truths are a priori scrutable. Chalmers’s three-part answer to this problem runs as follows: either the Continuum Hypothesis is indeterminate; or adding a new axiom will settle the issue; or, if these two options do not work, we should add the Continuum Hypothesis to the scrutability base. I argue that Chalmers’s (...) answer is unsatisfactory: the first horn of the trilemma can be interpreted in several ways, and either it departs from common mathematical practice and rests on weak analogies, or it shares the same problems with two other horns; the second horn does not provide good reasons to believe that from a fixed system of axioms all truths about our world are scrutable; the third horn of the trilemma renders Chalmers’s project empty.

Democratic alternation in power involves uncontrolled policy experiments. One party is elected on one policy platform that it then implements. Things may go well or badly. When another party is elected in its place, it implements a different policy. In imposing policies on the whole community, parties in effect conduct non-randomized trials without control groups. In this paper, we endorse the general idea of policy experimentation but we also argue that it can be done better by deploying in policymaking randomized (...) controlled trials. We focus primarily on the democratic benefits of using randomized trials in policymaking and on how they can enhance the democratic legitimacy of policy. We argue that randomized trials resonate well with three key democratic principles: non-arbitrariness, revisability and public justification. Randomized trials’ contribution to non-arbitrariness and revisability is not unique; other types of evidence can advance these democratic principles as well. But through their peculiar democratic scrutability, randomized trials are well-equipped to contribute to the public justifiability of policy. (shrink)

An attractive picture of the world is that some features are metaphysically fundamental and others are derivative, with the derivative features grounded in the fundamental features. But how do we have justified beliefs about which features are fundamental? What is the epistemology of fundamentality? I sketch a response in this paper. The guiding idea is that the same properties cause the same experiences. I argue that a probabilistic connection between epistemic fundamentality and metaphysical fundamentality is sufficient for justified beliefs about (...) the metaphysically fundamental. (shrink)

This highly technical book is densely packed with arguments and is an important addition to the literature. Even if one ultimately disagrees with Chalmers there is much to be gained in his exhaustive study, and he goes out of his way to show how one can accept limited or modified versions of scrutability. It is impossible for me to do justice to his argumentative rigor and comprehensive coverage of possible views in the space I have here. In the end (...) I find much of what Chalmers says convincing but something of a Pyrrhic victory. (shrink)
