Nature's Metaphysics argues that a satisfactory philosophy of science requires a metaphysics that is based on the understanding that causal properties are essentially dispositional properties. Alexander Bird develops and defends a dispositional essentialist account of the laws of nature, and also examines dispositional accounts of explanation, causation, ceteris paribus laws, substances and kinds. Professional philosophers and advanced students working in metaphysics and the philosophy of science will find this book both provocative and stimulating.
