David Lewis

David Lewis is one of the most important recent analytical philosophers. He has made important contributions to most areas of metaphysics and much of philosophy of science and language.

His work is based on the project of 'Humean Supervenience', which aims to characterise the world on the assumption that there is nothing to it but a number of matters of particular fact.


Lewis is one of the main proponents of the causal theory of explanation.


Lewis's presentation of the counterfactual theory of causation is extremely influential.
