Antihumanism

"Antihumanism" was first explicitly advanced as a philosophical position by the French philosopher and Communist Louis Althusser. In opposition to Marxist Humanism, Althusser proffered a radical incongruity between the humanism of Karl Marx's early writings and the later "scientific" theory of Marx's 'Das Kapital'. Althusser claimed to find latent in Marx's writings a revolutionary rejection of the distinction between subject and object.
Althusser's student Michel Foucault is another notable thinker described as "antihumanist". Alluding to Nietzsche's proclamation of the Death of God, Foucault's 1966 book The Order of Things talks of the "Death of Man". Foucault was critical of the belief that "human nature" was at the center of all morality.
Some extreme animal rights activists have been labeled as antihumanist,[1]sometimes correctly.

“The philosopher still makes some academics feel itchily uncomfortable, not because they truly believe his Nazism will leap from the pages of his works, but because his deeply anti-humanist arguments sound a little too familiar.” -- Tim BlackIn the academic world, especially in the Humanities, we are surrounded by anti-humanists postmodernists, left environmentalists, extreme animal activists, and various other sub-species. (I sometimes wonder whether—for the sake of truth in advertising—we should rename the “Humanities” divisions in our colleges the “Anti-Humanities.” Stephen Hicks, 2009
