Davidson on causal relevance (Mental properties)

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. © Blackwell Publishers Ltd. 1999.
