Finitude and Hume’s Principle

The paper formulates and proves a strengthening of Freges Theorem, which states that axioms for second-order arithmetic are derivable in second-order logic from Humes Principle, which itself says that the number of Fs is the same as the number ofGs just in case the Fs and Gs are equinumerous. The improvement consists in restricting this claim to finite concepts, so that nothing is claimed about the circumstances under which infinite concepts have the same number. Finite Humes Principle also suffices for the derivation of axioms for arithmetic and, indeed, is equivalent to a version of them, in the presence of Freges definitions of the primitive expressions of the language of arithmetic. The philosophical significance of this result is also discussed.

Hume’s naturalistic theory of representation

Hume is a naturalist in many different respects and about many different topics; this paper argues that he is also a naturalist about intentionality and representation. It does so in the course of answering four questions about his theory of mental representation: (1) Which perceptions represent? (2) What can perceptions represent? (3) Why do perceptions represent at all? (4) Howdo perceptions represent what they do? It appears that, for Hume, all perceptions except passions can represent; and they can represent bodies, minds, and persons, with their various qualities. In addition, ideas can represent impressions and other ideas. However, he explicitly rejects the view that ideas are inherently representational, and he implicitly adopts a view according to which things (whether mental or non-mental) represent in virtue of playing, through the production of mental effects and dispositions, a significant part of the causal and/or functional role of what they represent. It is in virtue of their particular functional roles that qualitatively identical ideas are capable of representing particulars or general kinds; substances or modes; relations; past, present, or future; and individuals or compounds.     

Quasi-Realism and Inductive Scepticism in Hume’s Theory of Causation

Interpreters of Hume on causation consider that an advantage of the ‘quasi-realist’ reading is that it does not commit him to scepticism or to an error theory about causal reasoning. It is unique to quasi-realism that it maintains this positive epistemic result together with a rejection of metaphysical realism about causation: the quasi-realist supplies an appropriate semantic theory in order to justify the practice of talking ‘as if’ there were causal powers in the world. In this paper, I problematise the quasi-realist reading of Hume on causation by showing how quasi-realism does not speak to inductive scepticism. I also offer evidence that Hume takes inductive scepticism to result from his theory of causation, and that his scepticism is tied to his rejection of metaphysical causal realism.     

David Hume’s Treatise of Human Nature

This ‘untimely review’ of Hume’s Treatise is written as if the book had just been published. I use this fiction to argue that the Treatise is a more fundamental critique of the concept of reason than most readers have thought. Hume’s analysis of human reasoning is grounded in empirical psychology, in which he made significant discoveries. He presents a non-propositional theory of desires, in which choice can be neither rational nor irrational. He shows that the idea that reason has authority, either in morality or science, has no substance. I argue that this critique remains valid and is not self-defeating.     

Moore’s Paradox and Moral Motivation

Assertions of statements such as ‘it’s raining, but I don’t believe it’ are standard examples of what is known as Moore’s paradox. Here I consider moral equivalents of such statements, statements wherein individuals affirm moral judgments while also expressing motivational indifference to those judgments (such as ‘hurting animals for fun is wrong, but I don’t care’). I argue for four main conclusions concerning such statements: 1. Such statements are genuinely paradoxical, even if not contradictory. 2. This paradoxicality can be traced to a form of epistemic self-defeat that also explains the paradoxicality of ordinary Moore-paradoxical statements. 3. Although a simple form of internalism about moral judgment and motivation can explain the paradoxicality of these moral equivalents, a more plausible explanation can be provided that does not rely on this simple form of internalism. 4. The paradoxicality of such statements suggests a more credible understanding of the thesis that those who are not motivated by their moral judgments are irrational.     

Naturalism,Experience, and Hume’s ‘Science of Human Nature’

Abstract

A standard interpretation of Hume’s naturalism is that it paved the way for a scientistic and ‘disenchanted’ conception of the world. My aim in this paper is to show that this is a restrictive reading of Hume, and it obscures a different and profitable interpretation of what Humean naturalism amounts to. The standard interpretation implies that Hume’s ‘science of human nature’ was a reductive investigation into our psychology. But, as Hume explains, the subject matter of this science is not restricted to introspectively accessible mental content and incorporates our social nature and interpersonal experience. Illuminating the science of human nature has implications for how we understand what Hume means by ‘experience’ and thus how we understand the context of his epistemological investigations. I examine these in turn and argue overall that Hume’s naturalism and his science of man do not simply anticipate a disenchanted conception of the world.     

Whence avidity? Hume’s psychology and the origins of justice

Hume’s account of the roots of justice focuses on the need to secure possession against the corrosive effects of unrestrained avidity. The reasons for this focus lie deep in his understanding of human psychology, especially, the mimetic passions shaped by the principles of sympathy, social referencing, and reversal comparison. The need for esteem drives human beings to attach their pride to those things they think are especially valued by those whom they especially admire. Most predominant among these goods are riches and possessions. Intense competition for these scarce goods puts the material and psychological survival of all in jeopardy. Conventions of justice are needed to civilize and channel avidity, transforming it from open and deadly violence and secret envy and malice into productive and public emulation.     

Working with Fischer and Ravizza’s Account of Moral Responsibility

This paper examines the account of guidance control given in Fischer and Ravizza's book, Responsibility and Control, with the aim of revising it so as to make it a better account of what needs to be added to having alternatives open to yield a specification of the control condition for responsibility that will be acceptable to an adherent of the principle that one is responsible for something only if one could have avoided it.     

Debunking,supervenience, and Hume’s Principle

ABSTRACT

Debunking arguments against both moral and mathematical realism have been pressed, based on the claim that our moral and mathematical beliefs are insensitive to the moral/mathematical facts. In the mathematical case, I argue that the role of Hume’s Principle as a conceptual truth speaks against the debunkers’ claim that it is intelligible to imagine the facts about numbers being otherwise while our evolved responses remain the same. Analogously, I argue, the conceptual supervenience of the moral on the natural speaks presents a difficulty for the debunker’s claim that, had the moral facts been otherwise, our evolved moral beliefs would have remained the same.     

Beyond sympathy: Smith’s rejection of Hume’s moral theory

Adam Smith’s Theory of Moral Sentiments (TMS) has long been recognized as importantly influenced by, and in part responding to, David Hume’s earlier ethical theory. With regard to Smith’s account of the foundations of morals in particular, recent scholarly attention has focused on Smith’s differences with Hume over the question of sympathy. Whilst this is certainly important, disagreement over sympathy in fact represents only the starting point of Smith’s engagement with – and eventual attempted rejection of – Hume’s core moral theory. We can see this by recognizing the TMS’s account of moral foundations as predicated upon a rejection of Hume’s distinction between the natural and artificial virtues. Smith is in turn revealed as generating a major break with Hume – a break which, if based on a superior theory of moral foundations (as Smith thought it to be) has important consequences for how we treat Smith and Hume in both the history of philosophy and contemporary moral theory.     

Politics and Practical Wisdom: Rethinking Aristotle’s Account of Phronesis

This paper examines the nature of Aristotelian phronesis, how it is attained, and who is able to attain it inside the polis. I argue that, for Aristotle, attaining phronesis does not require an individual to perfect his practical wisdom to the point where he never makes a mistake, but rather it is attained by certain individuals who are unable to make a mistake of this kind due to their education, habituation, and position in society.     

Kuhnianism and Neo-Kantianism: On Friedman’s Account of Scientific Change

Friedman’s perspective on scientific change is a sophisticated attempt to combine Kantian transcendental philosophy and the Kuhnian historiographical model. In this article, I will argue that Friedman’s account, despite its virtues, fails to achieve the philosophical goals that it self-consciously sets, namely to unproblematically combine the revolutionary perspective of scientific development and the neo-Kantian philosophical framework. As I attempt to show, the impossibility of putting together these two aspects stems from the incompatibility between (a) Friedman’s neo-Kantian conception of the role of philosophy and the role of the notion of incommensurability, and (b) the framework of transcendental idealism and the radical character of scientific revolutions. Hence, I suggest that pace Friedman and pace Kuhn’s own self-understanding, the Kuhnian theory of scientific revolutions cannot be seen as ‘Kantianism with moveable categories’ and consequently we should either abandon the notion of radical scientific revolution or place the Kuhnian account into another, non-Kantian philosophical framework.     

Hume’s Solution of the Goodman Paradox and the Reliability Riddle (Mill’s problem)

Many solutions of the Goodman paradox have been proposed but so far no agreement has been reached about which is the correct solution. However, I will not contribute here to the discussion with a new solution. Rather, I will argue that a solution has been in front of us for more than two hundred years because a careful reading of Hume’s account of inductive inferences shows that, contrary to Goodman’s opinion, it embodies a correct solution of the paradox. Moreover, the account even includes a correct answer to Mill’s question of why in some cases a single instance is sufficient for a complete induction, since Hume gives a well-supported explanation of this reliability phenomenon. The discussion also suggests that Bayesian theory by itself cannot explain this phenomenon. Finally, we will see that Hume’s explanation of the reliability phenomenon is surprisingly similar to the explanation given lately by a number of naturalistic philosophers in their discussion of the Goodman paradox.     

Moral internalism and moral cognitivism in Hume’s metaethics

Most naturalists think that the belief/desire model from Hume is the best framework for making sense of motivation. As Smith has argued, given that the cognitive state (belief) and the conative state (desire) are separate on this model, if a moral judgment is cognitive, it could not also be motivating by itself. So, it looks as though Hume and Humeans cannot hold that moral judgments are states of belief (moral cognitivism) and internally motivating (moral internalism). My chief claim is that the details of Hume’s naturalistic philosophy of mind actually allow for a conjunction of these allegedly incompatible views. This thesis is significant, since readers typically have thought that Hume’s view that motivation is not produced by representations, coupled with his view that moral judgments motivate on their own, imply that moral judgments could never take the form of beliefs about, or representations of, the moral (virtue and vice).
