Davidson argues that mental properties are causally relevant properties. I argue that Davidson cannot appeal to ceteris paribus causal laws to ensure that these properties are causally relevant, if he wishes to retain his argument for anomalous monism. Second, I argue that the appeal to supervenience cannot, by itself, give us an account of the causal relevancy of mental properties. I argue that, while mental properties may indeed ‘make a difference’ to the causally efficacious properties of events, this is not sufficient to show that mental properties are causally relevant.

Why is there something rather than nothing? Does God exist? Does time flow? What are we? Do we have free will? What is truth? Metaphysics is concerned with ourselves and reality, and the most fundamental questions regarding existence. This clear and accessible introduction covers the central topics in metaphysics in a concise but comprehensive way. Brian Garrett discusses the crucial concepts in a highly readable manner, easing the reader in with a look at some important philosophical problems. He addresses key areas of metaphysics: God Existence Modality Universals and particulars Facts Paradoxes of material constitution Causation Time Free will Personal identity Truth. This second edition has been thoroughly revised. Most chapters include substantial amounts of new material, and there are additional chapters on Existence, Modality, Facts and Paradoxes of Material Constitution. _What is this thing called Metaphysics?_ contains many helpful student-friendly features. Each chapter concludes with a useful summary of the main ideas discussed, a glossary of important terms, study questions, annotated further reading, and a guide to web resources. Text boxes provide bite-sized summaries of key concepts and major philosophers, and clear and interesting examples are used throughout.

Michael Dummett’s fecund and uncharacteristically brief article “A Defence of McTaggart’s Proof of the Unreality of Time” offers a well-known interpretation of McTaggart’s proof, and makes a number of controversial claims about a range of inter-connected theses concerning time and space. I want to sort out what is plausible in what Dummett says from what is not, and identify which theses should be endorsed by A theorists and which by B theorists. It is important, even today, to get clear about these issues and their bearing on Dummett’s interpretation of McTaggart.

Resumo Neste texto, o autor concentra-se em dois artigos históricos: o de Max Black “Why cannot an effect precede its cause”? e o de Michael Dummett “Bringing about the Past”. O autor irá mostrar onde falha o “bilking argument” de Black, contra a possibilidade da causalidade invertida. Por conseguinte, o autor irá concordar com Dummett, na possibilidade de um agente actuar a fim de que algo possa ocorrer no passado, contudo, discordando da argumentação de Dummett face a um desafio céptico, que tenta mostrar a inutilidade de afectar o passado. Palavras-chave : Black, causalidade invertida, Dummett, razões, tempoIn this discussion I focus on two classic articles: Max Black’s ‘Why cannot an effect precede its cause?’ and Michael Dummett’s ‘Bringing about the Past’. I argue that Black’s bilking argument against the possibility of backwards causation fails. I agree with Dummett that the idea of an agent acting in order that something should have happened in the past is not absurd, but I disagree with Dummett’s response to a sceptical challenge which attempts to show that it is pointless to attempt to affect the past. Keywords : backwards causation, Black, Dummett, reasons, time

David Chalmers claims that the logical possibility of ‘zombie worlds’ — worlds physically indiscernible from the actual world, but that lack consciousness — reveal that consciousness is a distinct fact, or property, in addition to the physical facts or properties.The ‘existence’ or possibility of Zombie worlds violates the physicalist demand that consciousness logically supervene upon the physical. On the assumption that the logical supervenience of consciousness upon the physical is, indeed, a necessary entailment of physicalism, the existence of zombie worlds implies the falsity of physicalism. How do we determine the logical possibility of zombie worlds? By conceptual analysis of the concepts involved, keeping empirical facts in mind.
