I will develop a new problem for almost all realist theories of colour. The problem involves fluctuations in our colour experiences that are due to visual noise rather than changes in the objects we are looking at.

The argument from causal overdetermination is considered to be the shortest route to token monism. It only assumes that:1.Efficacy: Mental events are causes of physical events.2.Closure: Every physical event has a sufficient physical cause.3.Exclusion: Systematic Causal Overdetermination is impossible: if an event x is a sufficient cause of an event y then no event x* distinct from x is a cause of y.4.Identity: Therefore, mental events are physical events.Exclusion does not deny the possibility of two gunmen that fi re at (...) a victim at the same time. But event-dualism is like a systematic fi ringsquad case — whenever I want to raise my arm, my arm is raised, and that is intolerable. (shrink)

Frank Jackson champions the cause of conceptual analysis as central to philosophical inquiry. In recent years conceptual analysis has been undervalued and widely misunderstood, suggests Jackson. He argues that such analysis is mistakenly clouded in mystery, preventing a whole range of important questions from being productively addressed. He anchors his argument in discussions of specific philosophical issues, starting with the metaphysical doctrine of physicalism and moving on, via free will, meaning, personal identity, motion, and change, to ethics and the philosophy (...) of color. In this way the book not only offers a methodological program for philosophy, but also casts new light on some much-debated problems and their interrelations. (shrink)

Physicalism is the idea that everything either is physical or is nothing over and above the physical. For this formulation of physicalism to have determinate content, it should be identified what the “physical” refers to; i.e. the body problem. Some other closely related theses, especially the ones employed in the causal arguments for different versions of physicalism, and more especially the causal closure thesis, are also subject to the body problem. In this paper, I do two things. First, I explore (...) the structure of causal arguments for physicalism that represents a general argument. To do this, the premises and the conclusion of the general argument are given exact formulations. Second, drawing on those premises, especially the causal closure thesis, I propose a naturalistic formulation of the physical that satisfies the requirements any formulation of the physical is expected to fulfill. Following this proposal, we also have a recursive algorithm to recognize the set of all physical events. (shrink)

RÉSUMÉ: La pragmatique et la sémantique de l’historiographie révèlent une fragmentation croissante qui s’étend par-delà les écoles jusqu’aux historiens individuels. Alors que les scientifiques normalisent les données pour qu’elles s’ajustent aux théories, les historiens interprètent leurs théories, de manières incompatibles entre elles, pour qu’elles s’ajustent aux différents cas historiques. Les difficultés qui en découlent dans la communication historiographique remettent en cause les philosophies herméneutiques de l’historiographie et redonnent un nouvel intérêt à la question d’une historiographie scientifique. Mais les réponses existantes (...) sont philosophiquement obsolètes. Une façon de reformuler le problème est de partir de la complexité du chaos et de l’unicité de l’histoire. Seule la science peut évaluer si les propriétés d’un domaine donné en interdisent une approche scientifique. Or la science s’étend par réductions méthodologiques explicatives, en ramenant des propriétés d’événements complexes, chaotiques et uniques, qui sont familières, mais d’un niveau plus élevé, à des propriétés ou interrelations non familières et d’un niveau moins élevé. La culture disciplinaire de l’historiographie, cependant, empêche le développement par essais et erreurs de telles tentatives de réductions scientifiques, qui seules permettraient d’évaluer les possibilités d’une historiographie scientifique, laquelle, dans la situation présente, relève de la science-fiction.

It has been argued that nonreductive physicalism leads to epiphenominalism about mental properties: the view that mental events cannot cause behavioral effects by virtue of their mental properties. Recently, attempts have been made to develop accounts of causal relevance for irreducible properties to show that mental properties need not be epiphenomenal. In this paper, I primarily discuss the account of Frank Jackson and Philip Pettit. I show how it can be developed to meet several obvious objections and to capture our (...) intuitive conception of degrees of causal relevance. However, I argue that the account requires large-scale miraculous coincidence for there to be causally relevant mental properties. I also argue that the same problem arises for two apparently very different accounts of causal relevance. I suggest that this result does not show that these accounts, on appropriate readings, are false. Therefore, I tentatively conclude that we have reason to believe that irreducible mental properties are causally irrelevant. Moreover, given that there is at leastprima facie evidence that mental properties can be causally relevant, my conclusion casts doubt on nonreductive physicalist theories of mental properties.
