One strategy for blocking Chalmers's overall case against physicalism has been to deny his claim that showing that phenomenal properties are in some sense physical requires an a priori entailment of the phenomenal truths from the physical ones. Here I avoid this well-trodden ground and argue instead that an a priori entailment of the phenomenal truths from the physical ones does not require an analysis in the Jackson/Chalmers sense. This is to sever the dualist's link between (...) conceptual analysis and a priori entailment by showing that the lack of the former does not imply the absence of the latter. Moreover, given the role of the argument from conceptual analysis in Chalmers's overall case for dualism, undermining that argument effectively undermines that case as a whole in a way that, I'll argue, undermining the conceivability arguments as stand-alone arguments does not.

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)

In this paper I examine Chalmers and Jackson’s defence of the a priori entailment thesis, that is, the claim that microphysical truths a priori entail ordinary non-phenomenal truths such as ‘water covers 60% of the Earth surface’, which they use as a premise for an argument against the possibility of a reductive explanation of consciousness. Their argument relies on a certain view about the possession conditions of macroscopic concepts such as WATER, known as ascriptivism. In the paper (...) I distinguish two versions of ascriptivism: reductive versus non-reductive ascriptivism. According to reductive ascriptivism, competent users of a concept have the ability to infer truths involving such concept from lower-level truths, whereas according to non-reductive ascriptivism, all that is required in order to be a competent user of a concept is to be able to infer truths involving that concept from other truths, which need not be lower-level truths. I argue, first, that the a priori entailment thesis is committed to reductive ascriptivism, and secondly, that reductive ascriptivism is problematic because it trivializes the notion of a priori knowledge. Therefore, I conclude that Chalmers and Jackson have not presented a convincing case for the claim that microphysical truths entail ordinary non-phenomenal truths a priori, especially when we understand this claim in the sense that is relevant for their argument against the possibility of a reductive explanation of consciousness.

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)

I defend the claim that physicalism is not committed to the view that non-phenomenal macrophysical truths are a priori entailed by the conjunction of microphysical truths , basic indexical facts , and a 'that's all' claim . I do so by showing that Chalmers and Jackson's most popular and influential argument in support of the claim that PIT ⊃ M is a priori, where 'M' stands for any ordinary, non-phenomenal, macroscopic truth, falls short of establishing its conclusion. My (...) objection to Chalmers and Jackson's argument takes the form of a nested dilemma. Let 'Conceptual Competence Principle ' stand for the following claim: for any complete microphysical description D of a world w, a subject who is in possession of and competent with a macrophysical concept C is capable of determining a priori the extension of C. Either Jackson and Chalmers accept CCP or not. If the latter, then they cannot demonstrate that the conditional PIT ⊃ M is a priori. If the former, then they have a choice: they can either cite reasons that support the principle or argue that the principle should be taken for granted since it is entailed by the very notion of conceptual competence. But both alternatives are problematic. In regard to the first horn of this latter dilemma, I show not only that there are no good reasons to support the principle, but that there are also reasons to reject it. In regard to the second horn, I show that it cannot be the case that CCP is part of the very notion of conceptual competence. The conceptual capacity expressed by CCP requires that certain bridge principles or conditionals, which link the microphysical level to the macroscopic level, are either implicitly or explicitly given to the subject. But, as I argue, Chalmers and Jackson have no way of accounting for these bridge principles or conditionals in a manner that does not trivialize their position. (shrink)

On rationalist infallibilism, a wide range of both (i) analytic and (ii) synthetic a priori propositions can be infallibly justified, i.e., justified in a way that is truth-entailing. In this paper, I examine the second thesis of rationalist infallibilism, what might be called ‘synthetic a priori infallibilism’. Exploring the seemingly only potentially plausible species of synthetic a priori infallibility, I reject the infallible justification of so-called self-justifying propositions.

One of the major challenges in the philosophy of religion is theological fatalism—roughly, the claim that divine omniscience is incompatible with free will. In this article, I present new reasons to be skeptical of what I consider to be the strongest argument for theological fatalism. First, I argue that divine foreknowledge is not necessary for an argument against free will if we take into account divine knowledge of contingent a priori truths. Second, I show that this argument can be (...) generalized so that ordinary human knowledge of contingent a priori truths also leads to an argument against free will. This, I believe, results in an absurd conclusion that is unacceptable to both theists and non-theists. But if there is something wrong with this argument, there is something wrong, too, with the argument for theological fatalism. Although there is a range of possible responses, I suggest that the core issue in all cases is a closure principle—specifically, the principle that ‘no choice about’ is closed under entailment (or strict implication).

According to the Classical Pessimistic Induction (CPI), otherwise positive features like predictive and explanatory success actually cast doubt on theories that display them. After all, they negatively correlate with truth. From this historical track record, it is inferred that current best theories are probably not (even approximately) true. The CPI is often wielded against realists about science, but others like Hume (1757), Pareto (1935), and Hájek (2007) extend it to philosophical theories more generally. In this paper, I unveil a (...) class='Hi'>priori refutations that defang the CPI in all its guises. To date, treatments of this topic typically assume the following: if the historical proportion of false theories increases, then it has increasingly negative bearing against realism. I show that this assumption is false. I identify three types of problems for the CPI, each attaching to some interpretation or other. The first problem is that the CPI violates a universal adequacy condition on the confirmation relation that restricts the relationship between entailment and disconfirmation. The second problem is that the induction’s target hypotheses preclude the track record from instantiating a list of epistemically significant properties that empirical information is supposed to afford. The third problem is that it is constitutively impossible for the CPI to have random samples; this implies that even the use of randomization procedures cannot help. In sum: my refutation is novel, accessible by pure reflection, and quite general. (shrink)

According to Perceptual Fundamentalism we can have justified perceptual beliefs solely in virtue of having perceptual experiences with corresponding contents. Recently, it has been argued that Perceptual Fundamentalism entails that it is possible to gain an a priori justified belief that perception is reliable by engaging in a suppositional reasoning process of a priori bootstrapping. But I will show that Perceptual Fundamentalists are not committed to a priori bootstrapping being a rational reasoning process. On the most plausible (...) versions of Perceptual Fundamentalism, a priori bootstrapping cannot be used to rationally support anti-sceptical beliefs about the reliability of perception. Moreover, seeing why Perceptual Fundamentalists are not committed to a priori bootstrapping will help us to better understand the nature of the perceptual entitlements that Perceptual Fundamentalists posit, or at least should posit.

In this paper, I argue against the view there are contingent a priori truths, and against the related view that there are contingent logical truths. I will suggest that in general, predicates ›a priori‹ and ›contingent‹ are implicitly relativized to circumstances, and argue that apriority entails necessity, whenever the two are relativized to the same circumstance. I will then criticize the idea, inspired by David Kaplan's framework, of contingent contents "knowable under a priori characters." I will also (...) argue, against Kaplan, that sentences of the form »The actual F is F« do not deserve the status of logical truths, since what they express is neither necessary nor a priori.

On rationalist infallibilism, a wide range of both (i) analytic and (ii) synthetic a priori propositions can be infallibly justified (or absolutely warranted), i.e., justified to a degree that entails their truth and precludes their falsity. Though rationalist infallibilism is indisputably running its course, adherence to at least one of the two species of infallible a priori justification refuses to disappear from mainstream epistemology. Among others, Putnam (1978) still professes the a priori infallibility of some category (i) (...) propositions, while Burge (1986, 1988, 1996) and Lewis (1996) have recently affirmed the a priori infallibility of some category (ii) propositions. In this paper, I take aim at rationalist infallibilism by calling into question the a priori infallibility of both analytic and synthetic propositions. The upshot will be twofold: first, rationalist infallibilism unsurprisingly emerges as a defective epistemological doctrine, and second, more importantly, the case for the a priori infallibility of one or both categories of propositions turns out to lack cogency. (shrink)

According to David Chalmers and Frank Jackson, conceptual competence puts one in a position to have a priori knowledge of conditional claims of the form ‘If my environment is thus and so, then water = H2O’. The rationale for this position, I argue, rests on controversial semantic assumptions about the individuation of meanings or concepts. I sketch a new model of conceptual competence, which undermines the apriority of such conditionals.

Both a priori physicalism and a posteriori physicalism combine a metaphysical and an epistemological thesis. They agree about the metaphysical thesis: our world is wholly physical. Most agree that this requires everything that there is must be necessitated by the sort of truths described by physics. If we call the conjunction of the basic truths of physics P, all physicalists agree that P entails for any truth Q. Where they disagree is whether or not this entailment can be (...) known a priori. The a priori physicalist says it can, the a posteriori physicalist says it cannot. Though a posteriori physicalism is probably the dominant view, it is really a surprising and somewhat unlikely stance. In this article, the nature of the view is discussed, and two arguments are presented that should cause us to look again at the potential of a priori physicalism. (shrink)

What has come to be known as “a priori physicalism” is the thesis, roughly, that the non-physical truths in the actual world can be deduced a priori from a complete physical description of the actual world. To many contemporary philosophers, a priori physicalism seems extremely implausible. In this paper I distinguish two kinds of a priori physicalism. One sort – strict a priori physicalism – I reject as both unmotivated and implausible. The other sort – (...) liberal a priori physicalism – I argue is both motivated and plausible. This variety of a priori physicalism insists that the necessitation of non-physical truths by the physical facts must be underwritten in a certain fashion by a priori knowledge, but the a priori knowledge need not amount to a simple deduction of the non-physical truths from a complete physical description of the world. Further, this sort of liberal a priori physicalism has the advantage that it offers hope for a genuinely satisfying account of how the physical facts manage to necessitate the facts about phenomenal consciousness – thereby in effect solving the “hard problem” of consciousness. The first half of the paper sets out the motivation for liberal a priori physicalism and its superiority to the strict version; the second half presents one strategy available to the liberal a priori physicalist for showing how consciousness can be accommodated in a purely physical world.

The topic of this article is the closure of a priori knowability under a priori knowable material implication: if a material conditional is a priori knowable and if the antecedent is a priori knowable, then the consequent is a priori knowable as well. This principle is arguably correct under certain conditions, but there is at least one counterexample when completely unrestricted. To deal with this, Anderson proposes to restrict the closure principle to necessary truths and (...) Horsten suggests to restrict it to formulas that belong to less expressive languages. In this article it is argued that Horsten’s restriction strategy fails, because one can deduce that knowable ignorance entails necessary ignorance from the closure principle and some modest background assumptions, even if the expressive resources do not go beyond those needed to formulate the closure principle itself. It is also argued that it is hard to find a justification for Anderson’s restricted closure principle, because one cannot deduce it even if one assumes very strong modal and epistemic background principles. In addition, there is an independently plausible alternative closure principle that avoids all the problems without the need for restriction. (shrink)

The attempt to hold both anti-individualism and privileged self-knowledge may have the absurd consequence that someone could know a priori propositions that are knowable only empirically. This would be so if such an attempt entailed that one could know a priori both the contents of one’s own thoughts and the anti-individualistic entailments from those thought-contents to the world. For then one could also come to know a priori the empirical conditions entailed by one’s thoughts. But I argue (...) that there is no construal of a priori knowledge that could be used to raise an incompatibility problem of this sort. First, I suggest that the incompatibilist a priori must be a stipulative one, since in none of the main philosophical traditions does knowledge of the contents of one’s thoughts count as a priori. Then, I show that under various possible construals of a priori, the incompatibilist argument would be invalid: either a fallacy of equivocation or an argument without a plausible closure principle guaranteeing transmission of epistemic status from premises to conclusion. Finally, I maintain that the only possible construal of the property of being knowable a priori that avoids invalidity is one that fails to generate the intended reductio. (shrink)

This essay reassesses the relation between Kant and Kripke on the relation between necessity and the a priori. Kripke famously argues against what he takes to be the traditional view that a statement is necessary only if it is a priori, where, very roughly, what it means for a statement to be necessary is that it is true and could not have been false and what it means for a statement to be a priori is that it (...) is knowable independently of experience. Call such a view the Entailment Thesis. Along with many Kant scholars, Kripke thinks that Kant endorses the Entailment Thesis. Thus Kripke and many others take his arguments against the Entailment Thesis to tell against Kant and to mark an important point of disagreement with him. I will argue that this is a mistake. Kant does not endorse the Entailment Thesis that Kripke and many others attribute to him. He does endorse two quite different theses concerning the relation between necessity and the a priori, as he conceives them. One is a matter of definition and the other is a very substantial philosophical thesis indeed—to establish it is the aim of the entire Critique of Pure Reason. But Kripke’s arguments against the Entailment Thesis tell against neither of Kant’s theses, as they involve crucially different conceptions of necessity and the a priori. This superficial lack of disagreement masks deep disagreements, but these result from divergent views regarding matters such as realism, modal epistemology, and philosophical methodology; views which Kant does a lot, and Kripke very little, to argue for.

Some truths about color are knowable a priori. For example, it is knowable a priori that redness is not identical to the property of being square. This extremely modest and plausible claim has significant philosophical implications, or so I shall argue. First, I show that this claim entails the falsity of standard forms of color functionalism, the view that our color concepts are functional concepts that pick out their referents by way of functional descriptions that make reference to (...) the subjective responses of perceivers. I then argue that, while some sophisticated forms of color functionalism can accommodate the a priori knowability of a truth like “redness is not identical to squareness,” they can only do so by abandoning color realism, the thesis that colors are instantiated by external material objects. In practice, color functionalists are almost invariably color realists. Thus, given extremely modest assumptions concerning what can be known a priori about color, we should conclude that color functionalism, at least in its typical realist form, is false. (shrink)

Broadly speaking, a naturalistic approach to epistemology seeks to explain human knowledge – and justification in particular – as a phenomenon in the natural world, in keeping with the tenets of naturalism. Naturalism is typically defined, in part, by a commitment to scientific method as the only legitimate means of attaining knowledge of the natural world. Naturalism is often thought to entail empiricism by virtue of this methodological commitment. However, scientific methods themselves may incorporate a priori elements, so empiricism (...) does not follow from the methodological commitments of naturalism alone. And given a suitably-naturalistic conception of the a priori, a priori forms of justification may be compatible with naturalism generally. A priori justification is, in principle, compatible with naturalism – and hence naturalistic epistemologies – if the a priori is understood in a way that is free of some of the inessential properties that have been associated with the concept. I argue that some of the more prominent strategies for accommodating normative notions within a naturalistic framework allow for the possibility of a priori justification. These include reliabilism, instrumental rationality, and nonfactualism about justification. A priori justification thus need not be seen as standing in opposition to all naturalistic epistemologies. It is only with nonnormative naturalistic epistemologies that a priori justification per se is incompatible, and this only because the notion of justification itself has no role to play within a nonnormative approach to epistemology.

The aim of the present work is to demonstrate that physicalism and a priori knowledge are epistemologically incompatible. The possibility of a priori knowledge on physicalism will be considered in the light of Edmund Gettier’s insight regarding knowledge. In the end, it becomes apparent that physicalism entails an unavoidable disconnect between a priori beliefs and their justificatory grounds; thus precluding the possibility of a priori knowledge. Consequently, a priori knowledge and physicalism are epistemologically incompatible.

Merely conceptual knowledge, not based on specific sensitivity to the referential domain, is not seriously a priori. It is argued here that it is either weakly and superficially a priori, or downright a posteriori. This is done starting from the fact that many of our definitions (or concepts) are recognizably empirically established, and pointing out that recognizably empirical grounding yields superficial apriority. Further, some (first-order) concept analyzing propositions are empirically false about their referents and thus empirically refutable. Therefore, (...) our empirical definitions (or concepts) are fallible and empirically revisable: they can turn out to be incorrect about the intended satisfiers of the concept defined, and their concept analyzing propositions to be false. Now, empirical revisability is incompatible with strong apriority (and entails at best a weak apriority or aposteriority). The result is quite shocking: analyticity does not entail apriority.

In his most recent treatment of a priori knowledge, Philip Kitcher argues against what he takes to be the widespread view that our knowledge and warranted belief is 'tradition-independent'. Furthermore, he argues that defeasible conceptions of a priori warrant entail that it is not tradition-independent, a conclusion which he thinks is contrary to what most epistemologists hold. I argue that knowledge is not widely believed to be tradition-independent, and that, while warrant is widely believed to be tradition-independent, Kitcher's (...) arguments show neither that this widespread view is mistaken nor that it conflicts with defeasible a warrant. I conjecture that Kitcher may be misled by a lack of clarity regarding the analysandum designated by 'warrant'. (shrink)

One of the major challenges in the philosophy of religion is theological fatalism — roughly, the claim that divine omniscience is incompatible with free will. In this article, I present new reasons to be sceptical of what I consider to be the strongest argument for theological fatalism.

Second, I show that this argument (...) can be generalized so that ordinary human knowledge of contingent a priori truths also leads to an argument against free will. This, I believe, results in an absurd conclusion that is unacceptable to both theists and non-theists. But if there is something wrong with this argument, there is something wrong, too, with the argument for theological fatalism. Although there is a range of possible responses, I suggest that the core issue in all cases is a closure principle — specifically, the principle that ‘no choice about’ is closed under entailment (or strict implication).

Sohn-Rethel’s theory undermines the line of thought that, from Kant to deconstruction, severs being or the thing from representation, by showing that the Kantian a priori categories of thought (representation) are a posteriori effects of the relations of things (being), to the point that it is ‘only through the language of commodities that their owners become rational beings’. This is the thesis of Marx’s theory of ‘commodity fetishism’, and Sohn-Rethel’s work develops the methodology that follows from it. ‘ Realabstraktion’ (...) means that the commodification of things amounts to their transformation into the language that provides the a priori categories of human thought. As a result, far from being inaccessible to representation, being is precisely that which reveals itself whenever the transcendental categories of representation are laid out. Therefore, Sohn-Rethel’s theory entails that not only can one not separate economy from thought but also economy and thought from being, so that there are no three distinct fields – economy, ontology and epistemology – but one: an economic epistemontology. Just as Marx’s ‘commodity fetishism’ introduced the unconscious in both subjectivity and economy – ‘they do this without knowing it’ – Sohn-Rethel analysed all economic, intellectual and practical spheres in terms of the fundamental distinction between consciousness and the unconscious. The article also points to certain corrections that Marx’s own theory indicates need to be made in Sohn-Rethel’s account, particularly regarding the source of abstraction, the role of coined money, and the difference between capitalist and pre-capitalist modes of production and exchange.

SummaryA familiar sort of argument for skepticism about the external world appeals to the evidential similarity between what is presumed to be the normal case and the case where one is a brain in a vat . An argument from Putnam has been taken by many to provide an a priori refutation of this sort of skeptical argument. The question I propose to address in this paper is whether Putnam's argument affords us an a priori refutation of skeptical (...) arguments that appeal to the claim that one does not know that one is not a BIV. I will develop a negative answer to this question along two related fronts. Along the first front I defend against new criticisms the common position that the externalism on which Putnam's argument is based entails skepticism about the meanings of sentences in our language and the contents of our thoughts. I do not take this to be a refutation of externalism or externalist arguments; rather, I see this as a motivation to locate the difficulty with arguments for externalism. But if externalism is abandoned, of course, the anti‐skeptical argument it has widely been taken to support must be abandoned along with it. I will argue, however, that this is not a significant loss, because along a second front I will argue that externalism cannot be given a priori justification; it is therefore ill‐suited to ground an a priori refutation of BIV skepticism anyway.

It has been argued that most truths about macroscopic states of affairs are entailed by a (hypothetical) complete descriptionPof the world in microscopic terms. In principle, micro-reductive explanations of non-microphysical truths could be constructeda priori.Against this claim, I show that reductive explanation requires knowledge about the phenomena to be reduced which cannot bea prioriextracted from microphysical information alone. Such reductions proceed in two steps: a “reductionR0” (“role-occupant”) establishes that a macroproperty M plays a certain causal role (specified in macro-terms), (...) while a “reductionMM” (“micro-macro”) establishes that some microproperty gives rise toM.

Frank Jackson uses the a priori entailment thesis to connect metaphysics and conceptual analysis. In the book he develops this thesis within the two-dimensional framework and also proposes a formal argument for it. I argue that the two-dimensional framework doesn’t provide independent support for the a priori entailment thesis since one has to build into the framework assumptions as strong as the thesis itself.

This paper advances a version of physicalism which reconciles the “a priori entailment thesis” (APET) with the analytic independence of our phenomenal and physical vocabularies. The APET is the claim that, if physicalism is true, the complete truths of physics imply every other truth a priori. If so, “cosmic hermeneutics” is possible: a demon having only complete knowledge of physics could deduce every truth about the world. Analytic independence is a popular physicalist explanation for the apparent “epistemic (...) gaps” between phenomenal and physical truths. The two are generally seen as incompatible, since the demon’s deductions seem to presuppose analytic connections between physical and phenomenal terms. I begin by arguing, in support of the APET, that implications from the complete truths of physics to phenomenal truths cannot be a posteriori. Such implications are (according to the physicalist) necessarily true. But they cannot be Kripke-style a posteriori necessities, since (according to the physicalist) the complete truths of physics fix any relevant a posteriori facts about the reference of terms. I then show how the physicalist can turn the tables: the demon can exploit the physical fixing of reference to bridge the gap between the vocabularies, by deducing when phenomenal and physical terms co-refer. This opens the way for a “type-C” physicalism, which accepts in-principle deducibility while still appealing to analytic independence to explain why we (who are not demons) find it impossible to see phenomenal-physical connections a priori.

The debate between exceptionalists and anti-exceptionalists about logic is often framed as concerning whether the justification of logical theories is a priori or a posteriori (for short: whether logic is a priori or a posteriori). As we substantiate (S1), this framing more deeply encodes the usual anti-exceptionalist thesis that logical theories, like scientific theories, are abductively justified, coupled with the common supposition that abduction is an a posteriori mode of inference, in the sense that the epistemic value of (...) abduction is (and, indeed, must be) a posteriori. In past work, however, we have argued that this common supposition is incorrect: abduction is an a priori mode of inference, in the sense that the epistemic value of abduction is (and indeed, must be) a priori (Biggs and Wilson 2017a, 2017b, 2019). After sketching our two main argumentative strategies for this conclusion (S2), we go on (S3) to consider its import on the proper understanding of anti-exceptionalism about logic. (shrink)

How should ‘the physical’ be defined for the purpose of formulating physicalism? In this paper I defend a version of the via negativa according to which a property is physical just in case it is neither fundamentally mental nor possibly realized by a fundamentally mental property. The guiding idea is that physicalism requires functionalism, and thus that being a type identity theorist requires being a realizer-functionalist. In §1 I motivate my approach partly by arguing against Jessica Wilson's no fundamental mentality (...) constraint. In §2 I set out my preferred definition of ‘the physical’ and make my case that physicalism requires functionalism. In §3 I defend my proposal by attacking the leading alternative account of ‘the physical,’ the theory-based conception. Finally, in §4 I draw on my definition, together with Jaegwon Kim's account of intertheoretic reduction, to defend the controversial view that physicalism requires a priori physicalism. (shrink)

A posteriori physicalism is the combination of two appealing views: physicalism (i.e. the view that all facts are either physical or entailed by the physical), and conceptual dualism (i.e. the view that phenomenal truths are not entailed a priori by physical truths). Recently, some philosophers such as Goff (2011), Levine (2007) and Nida-Rümelin (2007), among others, have suggested that a posteriori physicalism cannot explain how phenomenal concepts can reveal the nature of phenomenal properties. In this paper, I wish to (...) defend a posteriori physicalism from this new and interesting challenge, by arguing that a posteriori physicalists have the resources to explain how phenomenal concepts can reveal at least something of what it would take for the corresponding phenomenal property to be instantiated.

A central question within contemporary debates about the structure of self-love concerns the place and status of the other. Is self-love identical to, or at least vulnerable to, the accusation of self-absorption and narcissism? Whereas contemporary critiques of self-love argue self-love is in principle impossible, the present essay suggests that self-love can be integrated with the love of the other at an a priori level. This material a priori, distinct from the Kantian formal a priori, entails resources (...) such as commitment to myself, to the other, and to us as relational unit, as well as to the enforcement of boundaries that protects against acts of injury and abuse instigated against that relational unit; I suggest such resources overcome the charge of narcissism levelled at the very idea of self-love. Prior to that, a brief contextual discussion of key moves about philosophical anthropology, focused on the concept of the monad in Leibniz, Husserl and its extreme repudiation in Jean-Luc Marion, is to be addressed. Finally I assess the intimate relationship between self-love and the love of the other inspired in large part by Augustine’s anthropology. (shrink)

I will argue that internalism about justification entails the apparently absurd conclusion that it is possible to know specific facts about the external world—for example, that there is a tree in the quad—on the basis of introspection and a priori reflection. After a brief characterization of internalism (§1), I will set out the problem (§2). I will then discuss three replies: one that denies the form of doxastic voluntarism involved in the problem (§3), one that denies that knowledge of (...) higher-order facts about justification can justify corresponding first-order beliefs (§4), and, finally, one that involves biting the bullet (§5). I will argue that each reply fails. (shrink)

There is a long tradition in philosophy of using a priori methods to draw conclusions about what is possible and what is necessary, and often in turn to draw conclusions about matters of substantive metaphysics. Arguments like this typically have three steps: first an epistemic claim , from there to a modal claim , and from there to a metaphysical claim.

Taking Rom Harré's social constructionism as a focus we point to and discuss the issue of the a priori psychological subject in social constructionist theory. While Harré indicates that interacting, intending beings are necessary for conversation to occur, he assumes that the primary human reality is conversation and that psychological life emerges from this social domain. Nevertheless, we argue that a fundamental and agentive psychological subject is implicit to his constructionist works. Our critical analyses focus upon Harré's understandings of (...) persons, human development and human agency. Our intention is neither to suggest that this latent entity must be understood in a Cartesian sense nor is it to ask for an explicit accounting of an autonomous agent. Rather, our claim is simply that psychological subjectivity is reflexively entailed in Harré's human psychology. We suggest that this pertains more generally to social constructionist theory.

McKinsey-style incompatibilist arguments attempt to show that the thesis that subjects have privileged, a priori access to the contents of their thoughts is incompatible with semantic externalism. This incompatibility follows – it is urged – from the fact that these theses jointly entail an absurd conclusion, namely, the possibility of a priori knowledge of the world. In a recent paper I argued that a large and important class of such arguments exemplifies a dialectical failure: if they are valid, (...) the putatively absurd conclusion can be generated without the privileged access premise. Michael McKinsey has responded by arguing that the semantic externalist should adopt a neutral free logic invalidating a principle that my argument essentially relies on. I will say why the semantic commitments of the externalist are in tension with free logic, thereby vindicating my original argument. (shrink)

Is conceptual analysis required for reductive explanation? If there is no a priori entailment from microphysical truths to phenomenal truths, does reductive explanation of the phenomenal fail? We say yes . Ned Block and Robert Stalnaker say no.

The question examined in this study is not merely how a Nietzschean critique of law would look had Nietzsche ever applied his genealogical method to the question of law, but also what positive function Nietzschean philosophy may ascribe to law, and how law must then be transformed. The methodological parable imagines a “post-genealogy” or “pot-ressentiment” phase of the human condition, akin to the Marxist “post-revolutionary” phase: how would law look for the person of power - overman or otherwise - who (...) needs to live among others? How is normativity possible - what are its forms and functions - in a social world that has undergone a reevaluation of all values? The study traces three possible models for conceptualizing law in Nietzschean terms, each requiring a radical shift from traditional (in different contexts: liberal, Christian, bourgeois) conceptions. The first one is play: law as affirming and embracing the essence of the Dionysian, which is perpetual becoming. Play requires us to let go of law's role as the curtailer of arbitrariness. An integral part of the Nietzschean program, it requires a radical reevaluation: not just law's content is overcome, nor merely its bourgeois forms (in Pashukanis' critical terms), but its “internal” or “inherent” values of certitude and stability are overcome as well. The model I offer for play is not Zarathustra's dicethrow but Borges' The Lottery in Babylon. The second model is that of resistance, framed by Nietzsche's analysis of power and Deleuze's distinction between active and reactive forces. The insight here is that power requires resistance, and it is law's primary function to empower the other in order to invest value in meeting and confronting her; thus the monism of the will to power not only does not do away with normativity in the public sphere but actually requires it - but for goals opposite to those of liberalism. Resistance is linked to the third model, fashioned after Nietzsche's model of education: here, law performs not as a socializing agent but rather as a “liberator” of authenticity. Its function is analogous to that of a mentor whose role is to ultimately encourage the pupil into coming into her own will, shedding ressentiment and bad conscience in an active, i.e. non-conscious way; in its relation to consciousness it is the opposite of psychoanalysis. A fourth consideration is then offered, the role of normativity in self-overcoming, or self-legislating; namely, how does normativity figure in the will to power's most significant challenge. While all these models work from an interpretation of the will to power as becoming, the last two are especially dependent on the active-reactive distinction. The cornerstone is not to mix up power with representations of power; to realize that the case is not the will that desires power (as an object of desire, this would necessarily involve a representation of power) but power that wills becoming. In dealing with this metaphysical question I expound on a similar crucial interpretation, originally offered by Deleuze; however, I break off from Deleuze's claim that the will to power has nothing to do with any notion of struggle. If this discussion of the will to power is missed , or if it is wrong, the main argument of this article can not hold. Finally, I use this interpretation of the will to power to solve Kafka's riddle in The Trial: a necessary move once one realizes that, in the ethical history of western culture, Kafka's parable of the seeker of the law before its closed gates continues a sequence that began with Plato's fable of the cave and continued with Zarathustra's cave parable. I add three points that may be termed methodological or contextual. The first is positioning Nietzsche's limited discussion of law and politics as a derivative of his metaphysics of the will and treatment of moral psychology, not as an independent topic to be searched and indexed in some textual corpus. The second is to understand the question of normativity in its particularly Nietzschean sense, i.e. “what is X to me/to the overman?”, and not in the Kantian sense of uncovering the conditions that entail any synthetic, a-priori sentence (such as normative ones). The last comment places the Nietzschean project in a larger pattern that defined radical thought in the late nineteenth and early twentieth centuries, and whose other cases are Marx and Freud: a new metaphysics (will to power/materialism/id) that uncovers a state of bondage, psychological and material, in which law plays a pivotal role in its function of reinforcer and supplier of a legitimizing language (respectively, of ressentiment, of the relations of production, of Oedipus and the bourgeois family); and finally radical, yet partial ways of overcoming bondage that are not mutually translatable - genealogy, revolution, psychoanalysis.

One of the most central ideas of secular, humanistic morality is the thesis of intrinsic and equal human worth. Paradoxically, it is very hard to place this thesis in a secular worldview, because an indifferent universe can not make room for intrinsic values and a priori human rights. Nevertheless, it would not be a good solution to jettison the whole human rights discourse. Therefore, this paper proposes the stance of moral fictionalism: to believe that the discourse entails or embodies (...) a theory that is false, but to carry on employing the discourse, as if this were not the case, because it is useful to do so. As such, the ideas of intrinsic and equal human worth can be the subject of ëdisbelieving acceptanceí by the secular moral philosopher. (shrink)

It has become increasingly popular to suggest that non-individualistic theories of content undermine our purported a priori knowledge of such contents because they entail that we lack the ability to distinguish our thoughts from alternative thoughts with different contents. However, problems relating to such knowledge of 'comparative' content tell just as much against individualism as non-individualism. Indeed, the problems presented by individualistic theories of content for self-knowledge are at least, if not more, serious than those presented by non-individualistic theories. (...) Consequently, considerations of self-knowledge give one no reason to embrace individualism. If anything, they give one reason to reject it. (shrink)

Our conscious experiences seem to elude any explanation in scientific terms. They present paradigmatic case of reduction failure and they are the main motivation for postulating relations of emergence. Thus, various authors have pointed out that phenomenal properties must be something more than mere collections of physical properties. This leads to the rejection of physicalism. As a consequence, phenomenal properties either have to be added to the list of fundamental properties, or emerge from them. Alternatively, the physicalist must be able (...) to explain how that failure in the explanation can be compatible with their position. The aim of this paper is to clarify the concepts of reduction and emergence in the context of this debate in philosophy of mind, clearly distinguishing different types of epistemological relationships and their ontological consequences. This will allow us to have a better understanding of the commitments and the challenges different positions face. (shrink)

In this paper I argue that it is not a priori that all the laws of nature are contingent. I assume that the fundamental laws are contingent and show that some non-trivial, a posteriori, non-basic laws may nonetheless be necessary in the sense of having no counterinstances in any possible world. I consider a law LS (such as 'salt dissolves in water') that concerns a substance S. Kripke's arguments concerning constitution show that the existence of S requires that a (...) certain deeper level law or variants thereof hold. At the same time, that law and its variants may each entail the truth of LS. Thus the existence of S entails LS. Consequently there is no world in which S exists and fails to obey LS. I consider the conditions concerning the fundamental laws that would make this phenomenon ubiquitous. I conclude with some consequences for metaphysics. (shrink)

The paper argues for a metaphysics in the vein of the Canberra plan, namely to single out a minimal, basic set of entities and then to show how everything else is located in that set by being identical with something in that set and how the propositions that describe the basic entities entail all the other true propositions. The paper conceives the Canberra plan for the domain of the natural sciences as a naturalized metaphysics that is not committed to a (...) priori entailment. The proposal is that the minimal set of entities is defined by the following two axioms: There are distance relations that individuate simple objects, namely matter points. The matter points are permanent, with the distances between them changing. Finally, the paper explains how the Canberra plan sets a clear standard for ontological issues that go beyond the natural sciences. (shrink)

The goal of this paper is to articulate a new solution to Kant’s third antinomy of pure reason, one that establishes the possibility ofincompatibilist freedom—the freedom presupposed by our traditional conceptions of moral responsibility, moral worth, and justice—without relying on the doctrine of transcendental idealism (TI). A discussion of Henry Allison’s “two-aspect” interpretation of Kant’s TI allows me both to criticize one of the best defenses of TI today and to advance my own TI-free solution to the third antinomy by (...) appeal to a thesis of epistemic modesty based on Paul Guyer’s realist interpretation of Kant’s theory of experience. According to this interpretation, the a priori forms of our sensibility and understanding are not forms that the mind imposes on a material whose real properties are unknowable to us but are instead forms that limit or filter the kinds of things we can experience and know. In particular, being causally determined is a real feature of things as they are in themselves, but the necessity and universality of our deterministic claims are relative, restricted to the objects of possible experience. Consequently, though a causally determined event cannot be free, the necessity and universality of determinism does not entail that free events (choices) cannot exist but that they cannot constitute objects of possible experience. After arguing that freedom is possible, I outline an argument for the reality of freedom, based on therequirements of morality. Finally, I argue that my view, though opposed to metaphysical naturalism, is consistent with scientific realism and methodological naturalism. (shrink)

The paper explores the project of an ambitious modal epistemology that attempts to combine the a priori methods of Chalmers’ 2D semantics with Kripke’s modal metaphysics. I argue that such a project is not viable. The ambitious modal epistemology involves an inconsistent triad composed of (1) Modal Monism, (2) Two-Dimensionalism, and what I call (3) “Metaphysical Kripkeanism”. I present the three theses and show how only two of those can be true at a time. There is a fundamental incompatibility (...) between Chalmers’ Modal Rationalism and Kripke’s modal metaphysics. Specifically, Chalmers’ conceivability entails possibilities that a Kripkean rejects as genuinely metaphysical. However, three positive stances in modal epistemology emerge from the combinations that the triad allows. One of those offers a promising way forward for 2D modal epistemologies. But it comes with a cost, as it requires abandoning modal monism and reshaping the scope of what a priori conceivability can give us access to. (shrink)
