World-renowned author and professor Bryan Magee and London School of Economics professor Ernest Gellner discuss contemporary philosophy, its historical and social backgrounds, and its role in modern society. Gellner examines the radical expansion of scientific knowledge and its dehumanizing effect on society as expressed by sociologist Max Weber. Marxism’s messianic expectation is blamed for its failure to reconstruct society. Gellner dismisses today’s philosophy of relativism as unworkable.
