The Oxford Handbook of Causation provides an overview of topics related to causation, as well as the history of the causation debate from the ancient Greeks to the logical empiricists. Causation is a central topic in many areas of philosophy. In metaphysics, philosophers want to know what causation is, and how it is related to laws of nature, probability, action, and freedom of will. In epistemology, philosophers investigate how causal claims can be inferred from statistical data, and how causation is related to perception, knowledge, and explanation. In the philosophy of mind, philosophers want to know whether and how the mind can be said to have causal efficacy, and in ethics, whether there is a moral distinction between acts and omissions and whether the moral value of an act can be judged according to its consequences. In addition, causation is a contested concept in other fields of enquiry, such as biology, physics, and the law. The articles, which are all written by leading experts in the field of causation, provide surveys of contemporary debates, while often also advancing novel and controversial claims.
