Thoughts and oughts

Many now accept the thesis that norms are somehow constitutively involved in people's contentful intentional states. I distinguish three versions of this normative thesis that disagree about the type of norms constitutively involved. Are they objective norms of correctness, subjective norms of rationality, or intersubjective norms of social practices? I show the advantages of the third version, arguing that it improves upon the other two versions, as well as incorporating their principal insights. I then defend it against two serious challenges: (1) If content is constituted by others' normative judgments, how can content be causally efficacious? (2) This account appears to make having contentful thoughts a matter of people having contentful thoughts about your thoughts. That appears to be viciously circular and so can't be naturalistic.     

Philo’s Argument from Evil in Hume’s Dialogues X: A Semantic Interpretation

Philo's argument from evil in a much-discussed passage in Part X of Hume's Dialogues concerning Natural Religion (1779) has been interpreted in three main ways: as a logical argument from evil, as an evidential argument from evil, and as an argument against natural theology's inference of a benevolent and merciful God from the course of the world. I argue that Philo is not offering an argument of any of these sorts, but is arguing that there is a radical disanalogy between the meanings of terms like ‘merciful’ and ‘benevolent’ when applied to God and human beings respectively. Drawing on the new ‘Irreligious Interpretation’ of Hume's philosophy developed by Paul Russell (2002, 2008), I suggest that the underlying aim of Philo's argument appears to be to show, in opposition to Christian teaching, that these terms, when applied to God, are in effect meaningless.     

Causal Closure,Causal Exclusion,and Supervenience Physicalism

This article considers the recent defense of the supervenience approach to physicalism due to Jaegwon Kim. Kim argues that supervenience supports physical causal closure, and that causal closure supports physicalism – indeed, a kind of reductive physicalism – and thus that supervenience suffices for physicalism. After laying out Kim's argument, I ask whether its success would truly vindicate the role of supervenience in defining physicalist positions. I argue that it would not, and that insofar as Kim's defense of supervenience physicalism succeeds, it does so by showing that supervenience physicalism is not a unique, nonredundant way to be a physicalist.     

Laying Down Hume's Law

Most interpretations of Hume's is/ought passage (THN 3.1.1.27) can be broadly divided into two camps: those thinking Hume to rule out logical inferences from is to ought, and those thinking Hume to only raise surmountable difficulties for inferences from is to ought. I undermine the positive support for both these interpretations, and argue, by drawing parallels with Hume's argument on induction, that Hume's Law instead rules out all forms of inference from is to ought.     

Multiple realization,reduction and mental properties

This paper tries to remove some obstacles standing in the way of considering mental properties as both genuine natural kinds and causally efficacious rather than epiphenomena. As the case of temperature shows, it is not justified to conclude from a property being multiply realizable to it being irreducible. Yet Kim's argument to the effect that if a property is multiply realizable with a heterogeneous reduction base then it cannot be a natural kind and possesses only derivative “epiphenomenal” causal efficacy is not conclusive either. The fact that temperature is, but jade is not, a natural kind cannot be established by comparing the heterogeneity of their respective reduction bases, but rather by the fact that the former is and the latter is not embedded in laws of nature.     

Hume's nominalism and the Copy Principle

I consider some ways in which the Copy Principle (CP) and Hume's nominalism impinge on one another, arguing for the following claims. First, Hume's argument against indeterminate ideas isn't cogent even if the CP is accepted. But this does not vindicate Locke: the imagistic conception of ideas, presupposed by the CP, will force Locke to accept something like Hume's view of the way general terms function, the availability of abstract ideas notwithstanding. Second, Hume's discussion of nominalism provides support for the “old Hume” interpretation, that which takes the CP to be a criterion of meaningfulness, as against the “new Hume” reading, according to which it constrains what we can know. Finally, nominalism forces Hume to adopt a more complicated theory of ideas.     

Constitution,Over Determination and Causal Power

Kim's exclusion argument threatens to show that irreducible constituted objects are epiphenomenal. Kim's arguments are examined and found to be unconvincing; that a constituted cause requires its constituent to be a cause is not an adequate reason to reject the causation of the constituted object (event or property‐instance). However, I introduce and argue for, the Causal Power Uniqueness Condition (CPUC). I argue that CPUC and the causal closure of the physical, implies that constituted objects or property‐instances are not novel causal powers.     

The inertness of reason and Hume's legacy

Hume argues against the seventeenth-century rationalists that reason is impotent to motivate action and to originate morality. Hume's arguments have standardly been considered the foundation for the Humean theory of motivation in contemporary philosophy. The Humean theory alleges that beliefs require independent desires to motivate action. Recently, however, new commentaries allege that Hume's argument concerning the inertness of reason has no bearing on whether beliefs can motivate. These commentaries maintain that for Hume, beliefs about future pleasurable and painful objects on their own can produce the desires that move us to action. First, I show that this reading puts Hume at odds with Humeans, since the latter are committed, not only to the view that beliefs and desires are both necessary to action, but also to the view that beliefs do not produce desires. Second, I review textual, philosophical and historical grounds for my interpretation of Hume's argument for the inertness of reason. I argue that the new line on Hume, while consistent with a certain reading of the Treatise, is not supported by the Dissertation on the Passions and the second Enquiry, where Hume argues that all motivation has an origin in “taste”, which I take to be different from belief. Thus, Hume's arguments do support the contemporary Humean theory of motivation.     

Rehabilitating Warranted Assertibility: Moral Inquiry and the Pragmatic Basis of Objectivity

This article defends a pragmatic conception of objectivity for the moral domain. I begin by contextualizing pragmatic approaches to objectivity and discuss at some length one of the most interesting proposals in this area, Cheryl Misak's conception of pragmatic objectivity. My general argument is that in order to defend a pragmatic approach to objectivity, the pragmatic stance should be interpreted in more radical terms than most contemporary proposals do. I suggest in particular that we should disentangle objectivity from truth, and I claim that moral inquiry is in most cases responsive to a normative standard that is closer to warranted assertibility than to truth. Using an argument that relies partly on Huw Price's account of forms of normative assertion, I will show that a practice‐based account of warranted assertibility does the epistemic work required to defend objectivity while avoiding exposure to the criticisms that are usually addressed against this notion.     

Recognition,Freedom, and the Self in Fichte's Foundations of Natural Right

In this paper I present an interpretation of J. G. Fichte's transcendental argument for the necessity of mutual recognition (Anerkennung) in Foundations of Natural Right. Fichte's argument purports to show that, as a condition of the possibility of self‐consciousness, we must take ourselves to stand in relations of mutual recognition with other agents like ourselves. After reconstructing the steps of Fichte's argument, I present what I call the ‘modal dilemma’, which highlights a serious ambiguity in Fichte's deduction. According to the modal dilemma, the conclusion to Fichte's transcendental argument—that as a condition of the possibility of our self‐consciousness, we must recognize and be recognized by others—expresses either metaphysical or normative necessity. However, no normative conclusion follows from Fichte's premises, and the metaphysical claim that does follow from his argument appears to be implausibly strong. Thus the argument looks like a failure on either interpretation of the conclusion's modality. In the penultimate section of the paper, I propose a new interpretation of the argument that avoids the modal dilemma and provides a normative grounding of Fichte's concept of right.     

GLOBAL JUSTICE AFTER THE FALL Christian Realism and the "Law of Peoples"

In The Law of Peoples John Rawls casts his proposals as an argument against what he calls “political realism.” Here, I contend that a certain version of “Christian political realism” survives Rawls's polemic against political realism sans phrase and that Rawls overstates his case against political realism writ large. Specifically, I argue that Rawls's dismissal of “empirical political realism” is underdetermined by the evidence he marshals in support of the dismissal and that his rejection of “normative political realism” is in tension with his own normative concessions to political reality as expressed in The Law of Peoples. That is, I contend that Rawls, himself, needs some form of political realism to render persuasive the full range of normative claims constituting the argument of that work.     

Constitutivism and Transcendental Practical Philosophy: How to Pull the Rabbit Out of the Hat

Constitutivism aims to justify substantial normative standards as constitutive of practical reason. In this way, it can defend the constructivist commitment to avoiding realism and anti-realism in normative disciplines. This metaphysical debate is the perspective from which the nature of the constitutivist justification is usually discussed. In this paper, I focus on a related, but distinct, debate. My concern will not be whether the substantial normative claims asserted by the constructivist have some elements, which are not constructed, but real, given independently from us; instead, my concern will be more narrowly epistemic – whether those claims can be derived from premises, which are normatively less substantial than the normative conclusions themselves. I focus on Korsgaard’s transcendental articulation of the constitutivist argument. I conclude that more work would need to be done, in order for this argument to function as intended.     

Functions and emergence: when functional properties have something to say

In a recent paper, Bird (in: Groff (ed.) Revitalizing causality: Realism about causality in philosophy and social science, 2007) has argued that some higher-order properties—which he calls “evolved emergent properties”—can be considered causally efficacious in spite of exclusion arguments. I have previously argued in favour of a similar position. The basic argument is that selection processes do not take physical categorical properties into account. Rather, selection mechanisms are only tuned to what such properties can do, i.e., to their causal powers. This picture seems ultimately untenable in the light of further exclusion problems; but at the same time, it meets our explanatory demands. My purpose is therefore to show that there is a real antinomy with regard to evolved emergent properties. I develop a physicalist exclusion argument and then I go on to consider an argument that seems to establish that evolved emergent properties are causally efficacious, and propose a compatibilist solution. Finally, I very briefly consider what the proposed model may imply for the issue of mental causation.     

WHY FREE WILL REMAINS A MYSTERY

Peter van Inwagen contends that free will is a mystery. Here I present an argument in the spirit of van Inwagen's. According to the Assimilation Argument, libertarians cannot plausibly distinguish causally undetermined actions, the ones they take to be exercises of free will, from overtly randomized outcomes of the sort nobody would count as exercises of free will. I contend that the Assimilation Argument improves on related arguments in locating the crucial issues between van Inwagen and libertarians who hope to demystify free will, while avoiding objections these arguments have faced.     

A Plantingian Pickle for a Darwinian Dilemma: Evolutionary Arguments Against Atheism and Normative Realism

Two of the most prominent evolutionary debunking arguments are Sharon Street's Darwinian Dilemma for Normative Realism and Alvin Plantinga's Evolutionary Argument against Atheism. In the former, Street appeals to evolutionary considerations to debunk normative realism. In the latter, Plantinga appeals to similar considerations to debunk atheism. By a careful comparison of these two arguments, I develop a new strategy to help normative realists resist Street's debunking attempt. In her Darwinian Dilemma, Street makes epistemological commitments that ultimately support Plantinga's structurally similar argument. If Street succeeds in debunking normative realism, I argue, then she also succeeds in debunking atheism. But atheism is a suppressed premise of the Darwinian Dilemma as well as a commitment of almost all normative anti‐realists. If Street's argument entails theism, then the Darwinian Dilemma is internally incoherent and should be abandoned by almost everyone. 1     

Hume on Miracles: Would It Take a Miracle to Believe in a Miracle?

Given Hume's theory of belief and belief production it is no small task to explain how it is possible for a belief in a miracle to be produced. I argue that belief in a miracle cannot be produced through Hume's standard causal mechanisms and that although education, passion, and testimony initially seem to be promising mechanisms for producing belief in a miracle, none of these is able to produce the belief in a miracle. I conclude by explaining how this poses a problem for Hume's theory of belief and I briefly investigate the alternatives available for solving this problem.
