Althusser, who died in 1990, became a very influential French thinker – not only because he was a teacher for many intellectuals, but also because of his outspoken Marxist and anti-humanist opinions. He is known as a philosopher who tried to develop a structuralist version of Marxism. With the general demise of Marxist thinking, however, Althusser’s influence in the intellectual debates has faded away. For most of his life, he was an intellectual ally of the psychoanalyst Jacques Lacan, from whom he took some inspirations especially in regards to his theory of ideology. He was a very clear thinker who was not afraid to take a radical and critical position.
