My topic is Alvin Plantinga’s ’solution’ to one of the many forms that the problem of evil takes: the modal abstract form. This form of the problem is abstract in that it does not deal with the amounts or kinds of evil which exist, but only with the fact that there is some evil or other. And it is modal in that it concerns the compossibility of the following propositions, not any evidential relation between them:

Descartes, Boyle and Hooke shared, with many other seventeenth-century figures, the view that mechanical explanations were the only intellectually satisfactory ones. They also all accepted the view that we have incorporeal souls. This generated a problem for them when they wrote about perception. In this area, indeed, Descartes seems to be almost a reluctant Cartesian. When we read his scientific writings, the incorporeal soul is not stressed, and Descartes happily speaks of physical, or of corporeal, ideas in discussing sensation, memory and imagination.

Animalism is the doctrine that we human beings are – are identical with – animals. Hylemorphism is a form of animalism. In this paper, I defend hylemorphism by showing that while other forms of animalism fall prey to the problem of ‘Remnant Persons, ’ hylemorphism does not. But hylemorphism’s account of personhood seems to have some very implausible implications. I address one of those implications, and argue that it isn’t nearly as objectionable as it might at first appear.

Hume finds himself in an appalling state during Treatise I iv 7 (the conclusion of Book I). He is almost bereft of beliefs; he believes, for a short time, only that he cannot believe anything else. But, being an assiduous student of human nature, Hume makes this extreme skeptical crisis into material for naturalistic study. He carefully reports how extreme skepticism comes about, what it is like, and how it passes. So I iv 7 has two aspects: involved personal experience of a skeptical crisis, and detached naturalistic reflection on that crisis. Interpreting the text correctly requires taking both these aspects seriously.

An old interpretive tradition ignores or downplays Hume's detached naturalistic reflections in I iv 7, and focuses only on his involved personal experience of skepticism. Oddly enough, interpretations in this tradition tend to treat Hume's experience dismissively and derisively.

Philosophers since the ancient Greeks have investigated the nature of different kinds of inference. Although deductive inference in the form of Aristotelian syllogisms and Fregean formal logic has predominated, much attention has also been paid to induction, inference where the conclusion does not follow necessarily from the premises.

Modesty is a surprisingly complicated character trait. Most of us feel that we intuitively understand what modesty is, and we feel confident that we can recognize modesty when it is exhibited in others. However, it is difficult to provide a detailed account of modesty without discovering that it is not nearly as simple as one initially presumes it to be. For example, in her recent book Uneasy Virtue, Julia Driver proposes a definition of modesty that seems uncomplicated until further reflection reveals it to be more intricate and contentious than it appears. Driver claims that modesty is the virtue of being disposed to persistently underestimate one's self-worth despite available evidence suggesting that this estimation is incorrect. There is something compelling about such a concise definition of modesty, but Driver's view implies that a modest agent is truly ignorant of her natural talents, accomplishments or other attributes that contribute to assessments of her self-worth. It is this feature of Driver's definition that has generated debate since she first presented her view of modesty in an influential article that preceded her book.

In Religion within the Boundaries of Mere Reason Kant wrote that ‘freedom of the power of choice has the characteristic, entirely peculiar to it, that it cannot be determined to action through any incentive except insofar as the human being has incorporated it into his maxim.’ This is an obscure statement, in both meaning and provenance. Yet almost all recent interpreters of Kant's practical philosophy find it crucial for understanding his theories of freedom and motivation, since it seems to indicate what we are required to do in order to act by our own free choice. Here I refer to Kant's statement expressing the requirement that incentives be incorporated into maxims as his ‘incorporation requirement.’ How that requirement is best understood will be the leading question in what follows: a question I shall answer by showing why the incorporation requirement, and Kant's theories of freedom and motivation, should be understood differently from the way they are now usually understood.

According to the Asymmetry, we’ve strong moral reason to prevent miserable lives from coming into existence, but no moral reason to bring happy lives into existence. This procreative asymmetry is often thought to be part of commonsense morality, however theoretically puzzling it might prove to be. I argue that this is a mistake. The Asymmetry is merely prima facie intuitive, and loses its appeal on further reflection. Mature commonsense morality recognizes no fundamental procreative asymmetry. It may recognize some superficially similar theses, but we will see that they derive from more familiar principles, and are compatible with there being moral reason to bring happy lives into existence.

We have conflicting pre-philosophical intuitions about what it means ‘to be true to ourselves.’ On the one hand, autonomy and authenticity seem closely connected to the lucidity of reflectiveness; on the other, they seem tightly interwoven with the immediacy of unreflectiveness. As opposed to a ‘Platonic’ intuition about the inferiority of the unexamined life, we have an equally strong ‘Nietzschean’ intuition about the corrosiveness of the examined life. Broadly speaking, the first intuition is more akin to the tradition of the Enlightenment, and the second, more to that of Romanticism; the one is reminiscent of Descartes and Hume, the other of Rousseau and Herder.

The use of the technical term ‘autonomy’ and the concomitant term ‘self’ is primarily limited to philosophy, while in daily life ‘freedom’ and ‘person,’ respectively, are used instead. Unfortunately, in their deployment of these technical terms philosophers have generally failed to acknowledge the two modes of ‘being true to ourselves’ associated with the Enlightenment and Romanticism, for they usually employ the concept of autonomy in a unitary way.

Newcomb's paradox was first presented by Robert Nozick and has been discussed by a considerable number of writers. You are playing a game with a Being who seems to have extraordinary predictive powers. Before you are two boxes, in one of which you can see $1,000. The other is closed and you cannot see what it contains, but you know that the Being has put a million dollars into it if he has predicted that you will take it only, but nothing if he has predicted that you will take both boxes; you may take either both boxes or the closed one only. The Being has correctly predicted the choices of all who have so far played with him. What should you do?

Let us call the Being the seer, and his opponent the player. I should also like to reduce the amount that may, or may not, be in the closed box to $10,000. Nearly everyone could make good use of $1,000 and better use of $10,000 or $11,000, but it is hard to say whether a million dollars would be a blessing or a curse.

Determinism is the thesis that ‘there is at any instant exactly one physically possible future.’ When various compatibilists discuss determinism and moral responsibility, they champion the view that although determinism is inconsistent with freedom to do otherwise, it is nevertheless consistent with responsibility. Determinism, then, does not, in the view of these compatibilists, threaten one sort of moral appraisal — the sort we make, for example, when we say that someone is blameworthy for some deed. Call moral deontic normative statuses like those of being morally right, wrong, or obligatory, ‘moral anchors.’ A key objective of this paper is to show that even if compatibilists can secure moral responsibility against the threat of determinism, possibly, by establishing that freedom to do otherwise is not the right sort of freedom required for responsibility, they will not be able to secure the very anchors of morality by any similar line of reasoning. Specifically, I argue that if certain principles of moral obligation are true, nothing can be morally right, wrong, or obligatory in a world in which we lack alternative possibilities. Thus, whereas unfreedom to do otherwise may be compatible with responsibility, it is incompatible with moral anchorage.

Logical consequence is a notion that every person who reasons must possess, at least implicitly. To give a precise and accurate characterization of this notion is the fundamental task of logic. In a similar way, the notion of effectivity is a concept that anyone with a basic training in mathematics possesses, and the most fundamental task of a theory of computability is to give a precise characterization of this notion. The problem concerning effectivity was solved (at least to the satisfaction of most people) in the 1930s, almost as soon as it was raised, by the work of Turing, Church, and others. By contrast, the correct and precise characterization of logical consequence has been hotly contested through the two and a half thousand-year history of logic.

I Introduction

Let's assume there are psychological generalizations that the folk rely upon in explaining and predicting the behavior of their fellows. Let's further assume these generalizations are intentional, in that they do their explanatory and predictive work by attributing to the subjects in their domain intentional mental states such as beliefs, desires, and the like. Then we can define a broad intentional psychology as one that adverts only to broad, viz. purely denotational/ truth-conditional, mental contents in its generalizations; so the sentences expressing its generalizations should be read transparently. A narrow psychology is one that is not so restricted. Accordingly, sentences expressing narrow generalizations will contain opaque contexts, indicated by ‘that’ -clauses ('believes that…,’ ‘desires that … ,’ and the like). Here is an example of the sort of generalization we have in mind:

Although it may exaggerate to say that Descartes fathered the mechanization of biology, it is true (without qualification) that his Treatise of Man provided the first systematic development of the idea that a complete understanding of all the phenomena of life, including all abilities and behaviour of (non-human) animals, can be achieved by viewing living things as machines. To make this out, Decartes had to learn to think about living things in a new way. My first aim here is to identify the fundamental conceptual innovations at work in Descartes’ attempt to extend the new mechanics to include biology. My second aim is to locate the point at which Descartes’ mechanical imagination runs out. This requires study of Descartes’ scientific work on sense.

Knowing that p requires being able to ‘rule out’ the relevant not-p alternatives. Such is the core claim of the Relevant Alternatives (RA) theorist. Of course, to endorse the core claim is not to have a complete and satisfactory account of knowing: any RA theorist has some explaining to do. Most obviously, anyone who endorses the core claim must ultimately provide an account of ‘ruling out’ and ‘relevance’. And some who‘ve been critical of the whole RA approach have done so because of a scepticism about the prospects of cashing these notions out in a satisfactory way.

I have claimed that risk-weighted expected utility (REU) maximizers are rational, and that their preferences cannot be captured by expected utility (EU) theory. Richard Pettigrew and Rachael Briggs have recently challenged these claims. Both authors argue that only EU-maximizers are rational. In addition, Pettigrew argues that the preferences of REU-maximizers can indeed be captured by EU theory, and Briggs argues that REU-maximizers lose a valuable tool for simplifying their decision problems. I hold that their arguments do not succeed and that my original claims still stand. However, their arguments do highlight some costs of REU theory.

Truth conditional semantics is the project of ‘determining a way of assigning truth conditions to sentences based on A) the extension of their constituents and B) their syntactic mode of combination’ (Rothschild and Segal, 2009). This research program has been subject to objections that take the form of underdetermination arguments, an influential instance of which is presented by Travis:

Different people live different lives. Each life consists of experiences that are not shared with the other lives. These facts are sometimes referred to as the ‘separateness of persons.’ Some writers have appealed to the separateness of persons to support or to criticize moral views. John Rawls thinks that the separateness of persons supports egalitarianism, while Robert Nozick believes that it supports a rights view. I will call the claim that the separateness of persons counts in favor of a particular moral view the ‘positive connection.’ Both these writers think that utilitarianism is objectionable because it ignores the moral importance of the separateness of persons. I will call the claim that the separateness of persons counts against a moral view the ‘negative connection.’

In this paper I will discuss several different attempts at explaining the connection between the separateness of persons and specific moral views. I will begin by describing how egalitarianism, unlike utilitarianism, treats individual lives as morally important units. I will discuss the kind of egalitarianism that aims at equality, but the same points could be made about egalitarian views that give priority to helping the worst off or require that everyone should receive at least a specified minimum share of resources or happiness.

'Some beliefs about the world are justified, others are not.’ This seems to be a plausible, even if not completely uncontroversial, claim. The controversy most likely would center on the meaning given to the term ‘justified'. If one gives extremely strong criteria for justification, one might argue that the claim is false. None of our beliefs about the world are justified. It is possible, perhaps, to interpret Hume as taking such a position.

Whether or not Hume held this, I think that there is a sense of ‘justified’ in which Hume could have argued that some of our beliefs about the world are justified. I will try to show this by developing an analysis of justified belief that is compatible with Hume's theory of the nature of beliefs and belief formation. As a minimum criterion for success such an analysis must be able to provide a plausible basis for distinguishing between justified and unjustified beliefs.

People do, quite naturally and not uncommonly, speak of other people as deceiving themselves, as being their own dupes. A man's child is ill and growing constantly worse. The father keeps talking optimistically about the future, keeps explaining away the evidence, and keeps pointing to what he insists are signs of improvement. We can easily imagine ourselves deciding that he has deceived himself about his son's condition. Nor is it the case that talk of self-deception is appropriate only in connection with other people. We can easily imagine the father admitting, say, after the son's death, that he has deceived himself about the child's condition. Thus the notion of self-deception obviously has application. Furthermore, ordinarily talk of self-deception is not thought to be puzzling.
