1047Causation is defined as a relation between facts: C causes E if and only if C and E are nomologically independent facts and C is a necessary part of a nomologically sufficient condition for E. The analysis is applied to problems of overdetermination, preemption, trumping, intransitivity, switching, and double prevention. Preventing and allowing are defined and distinguished from causing. The analysis explains the direction of causation in terms of the logical form of dynamic laws. Even in a univ…Read more

67Introduces 'Turing Worlds' as a device for thinking about Metaphysical Problems and uses them to examine several different theories of counter-factuals.

55Our justification for punishing the wrong doer is not that we are enacting God-like retribution. Neither do we have to argue that inflicting the punishment will make any person, living or dead, happier or better off. We punish to keep a promise to the victims: a promise made before they were victims, a promise they were entitled to ask for; that we were entitled to give and that we are now obliged to honor.

118The standard account of counterfactuals that most philosophers endorse—Lewis's 'Analysis 1' — is wrong. The correct theory is one invented by Jonathan Bennett in 1984 which he called 'The Simple Theory'. Bennett later argued himself out of that theory and went on to champion the standard account. But those arguments fail. The Simple Theory has been right all along.

99Quine taught us that the collapse of positivism entails that empirical theories are, in principle, undetermined-- not just by the available evidence-- but by all possible evidence. Without disputing that conclusion, contemporary philosophers-- exampled here by Simon Blackburn and Jerry Fodor-- have wanted to treat this as a merely abstract possibility that need not undermine our confidence in actual scientific theory and practice. I argue that there is no basis for this complacency.

153The Computational Theory of the Laws of Nature entails that the accessibility relation for nomological necessity is not symmetric or transitive. This means that nomologically possible worlds need not share our world's laws. This subverts a standard style of argument against Humean Supervenience.

48What is Grammar?Canadian Journal of Philosophy 10 (sup1): 61-82. 1980.While there is agreement that it is the central task of semantics to give the semantic interpretation of every sentence in the language, nowhere in the linguistic literature will one find, so far as I know, a straightforward account of how a theory performs this task, or how to tell when it has been accomplished. The contrast with syntax is striking. The main Job of a modest syntax is to characterizemeaningfulness. We may have as much confidence in the correctness of such a characterization as w…Read more

113If there are rights there is surely a right to self-defense. But self-defense has proved very puzzling to rights theorists. The central puzzle has been called the "paradox of self-defense": If our right not to be harmed gives rise to our right to fight back, what happens to the attacker's right not to be harmed when the defender fights back? If the attacker somehow forfeits his right to self-defense because he is a bad actor, what do we say about innocent threats? I argue that these problems…Read more
