 Alexandre Kojève (1902–1968) was a Marxist and Hegelian political philosopher, who had a substantial influence on intellectual life in France in the 1930s and on the reading of Hegel in France.Louis Althusser (1918–1990) was a key Marxist philosopher, sometimes considered to be the structuralist equivalent to Marxism that Lacan was to Psychoanalysis and Claude Lévi-Strauss to ethnology (although all of them rejected the identification).In 'Lenin and Philosophy', Althusser explained Lenin's differentiation between [Dialectical Materialism] and [Historical Materialism].
