A politically oriented study of the thought of the founders of the main schools of contemporary academic philosophy, those which dominate nearly all universities throughout the world. It concentrates on four key masters: Wittgenstein, who founded both Logical Positivism and the so-called Common Language or Analytic school; Heidegger, the acknowledged master of Hermeneutic Philosophy or the so-called Continental school; Lukacs, the founder of Hegelian Marxism and the leading Communist philosopher of the Soviet period; and, finally, the now lesser-known Gentile, the Hegelian Idealist.
