A Reductio for Reliabilism. Hilary Kornblith has recently offered a defence of reliablism against bootstrapping arguments. He says that if reliablism is true, bootstrapping beliefs are not justified. I argue that he hasn't refuted the critics’ claim that if reliabilism is true, bootstrapping beliefs are unjustified. These two conditionals imply that reliabilism is false.

Defending Causal Decision Theory. I reply to the attacks on causal decision theory in Andy Egan’s Against Causal Decision Theory. I isolate the kind of example that is crucial to Egan’s argument, and the principle concerning such a case that he uses to attack causal decision theory. Then I argue that if we use that principle in making decisions between 3 choices (not just 2 as Egan primarily considers) we end up with absurd results.

Probability and Scepticism. I consider a probabilistic defence of a crucial premise in the Humean argument for scepticism. The premise says that if the probability of an anti-sceptical claim (like I’m not a brain in a vat) does not go up when we get empirical information, then we cannot have learned that claim empirically. I defend the premise against some putative counterexamples by appeal to a version of interest-relative invariantism about knowledge. (Some serious counterexamples to the proposal in this paper were raised at the 2009 Arché Scepticism conference, and I may eventually have to scrap this paper.)

Evidence ≠ Knowledge. I argue that only some of our knowledge, in particular only our knowledge that is obtained directly, is evidence, contra Williamson's view that all knowledge is evidence.

Rule-Following and Basicness. Building on some suggestions David Christensen has recently made, I suggest that we can use epistemic dilemmas as a diagnostic tool for determining which inferential rules are properly basic. I think this paper will eventually be split into two, one criticising Christensen’s development of some of his cases, and the other on rules. Some of this paper has been incorportated into Do Judgments Screen Evidence.

Moderate Rationalism and Bayesian Scepticism. I argue that an epistemologist who thinks (a) we can know a lot a priori about the nature of justification, but (b) we can't know anything a priori that could have turned out to be false, has no response to a certain sceptical argument based on Bayesian considerations.

Dutch Books and Infinity. Peter Walley argues that a vague credal state need not be representable by a set of probability functions that could represent precise credal states, because he believes that the members of the representor set need not be countably additive. I argue that the states he defends are in a way incoherent.

Game Playing Under Ignorance. In earlier work I argued that using ‘vague probabilities’ did not ground any argument for significantly adjusting Bayesian decision theory. In this note I show that my earlier arguments don’t carry across smoothly to game theory. Allowing agents to have vague probabilities over possible outcomes dramatically increases the range of possible Nash equilibria in certain games, and hence arguably (but only arguably) increases the range of possible rational action.

Morality in Fiction and Consciousness in Imagination. I argue that the cases that motivate the imaginative resistance literature show that there are some problems for David Chalmers's Zombie Argument.

Generality and Modularity. I outline a new solution to three pressing problems for reliabilism, the generality problem, the new evil demon problem and the problem of epistemic luck, based on Fodor’s theories concerning the modularity of mind.

Three Objections to Smith on Vagueness. Nick Smith recently defended a definition of vagueness in terms of blurred boundaries. I argue that (a) vague predicates need not haveany boundaries and hence no vague boundaries, (b) some vague predicates have lumpy rather than blurry boundaries and (c) some things that aren’t predicates are vague, so the definition won’t work.

Vagueness Without Toleration: Reply to Greenough. Patrick Greenough has argued that a predicate is vague iff it is epistemically tolerant. I show that there are some counterexamples to this analysis, and that it rests on some fairly contentious theories about the behaviour of vague terms in propositional attitude reports.

Growing Individuals and Temporary Intrinsics. I argue that ordinary objects are fusions of past and present, but not future, temporal parts. This theory provides the neatest solution to some puzzles concerning intrinsic properties, and is supported by some surprising linguistic data. (This paper is probably inconsistent with some other papers I've written, but the line it runs is at least amusing and original.)

Knowing and Understanding: Reply to Pettit (with Adam Sennet). Dean Pettit recently argued in Mind that understanding a word did not require knowing what it meant. Adam and I show that his core arguments, which mostly turn on showing that some particular cases are cases of understanding without knowledge, do not work.

Solving an Infinite Decision Problem. In a recent paper in Theory and Decision, Barrett and Artzenius propose a puzzle concerning a particular infinite series of choices. The puzzle turns out to be easy to resolve once we distinguish between use-value and exchange-value.

Conditionals, Predicates and Probability. Adams's Thesis is meant to explain our judgements about the validity of arguments involving conditionals. I note it goes wrong in some simple cases involving quantifiers.

Stages, Worms, Slices and Lumps. Assume, for fun, that temporal parts theory is true, and that some kind of modal realism (perhaps based on ersatz worlds) is true. Within this grand metaphysical picture, what are the ordinary objects? Do they have many temporal parts, or just one? Do they have many modal parts, or just one? I survey the issues involved in answering this question, including the problem of temporary intrinsics, the problem of the many, Kripke's objections to counterpart theory and quantifier domain restrictions.

Vague Decision Theory. Many smart people (and me) think that partial beliefs are best represented by sets of probability functions rather than single probability functions. There is no consensus as to how these sets of probability functions should enter into decision making. I survey the field, find all the proposals lacking, and suggest an alternative.

Doomsday and the Extinction of Baseball. John Leslie's Doomsday argument uses the frequency interpretation of probability to argue that the end of the universe is closer than we might have thought. Oh well - all the worse for the frequency interpretation.
