The death of David Lewis at the age of 60 has deprived philosophy of one of its most original and brilliant thinkers. Lewis was a systematic philosopher in a traditional sense, who created a system of thought (or metaphysical system) which attempts to reconcile the insights of modern science with pervasive elements of commonsense belief. Lewis was not a populariser and he had little to do with the more concrete and practical areas of philosophy. His work is forbiddingly abstract, and (...) deals with many of the deepest and most difficult of philosophy’s traditional concerns, including the nature of mind, causation, necessity and being.
