Laws of nature play a prominent role in modern science as well as in many areas in philosophy. Laws have a close conceptual relation to explanation, confirmation, causation, counterfactuals and probabilities. They are also involved in metaphysical issues concerning reduction and freedom of will. Nonetheless, the nature, or even the existence, of natural laws is a contentious issue. This course provides a general introduction into the major philosophical problems concerning laws of nature. The course is structured around three main topics. First, we shall discuss the classical empiricist accounts of laws, induction and explanation; then we shall investigate some specific kinds of laws (fundamental, statistical, ceteris paribus, causal laws); and finally, we shall address the metaphysics of laws and properties.
