Antihumanism, a term that stands for the rejection of humanism, on the ground of that humanism is an pre-scientific ideology. It was developed during the 18th and 19th  century, parallel with the advancement of humanism, objection to humanism by prominent thinkers arose, that questioned the metaphysics of humanism, as the human nature and its concept of freedom . Nietzsche, while departing from a humanistic, pro-Enlightenment point, criticizes humanism for illusions in a number of topics, especially about the nature of truth. For him, objective truth were merely anthropomorphic illusions and hence humanism was meaningless. Furthermore, replacing theism with reason, science and truth is nothing but replacing one religion with another, Nietzsche argued. Karl Marx belittled his contemporary precursors of humanism as a bourgeois project that attempts to present itself as radical- but is not. After World War II atrocities, questions on human nature and human concept, renewed. During Cold War, influential Marxist philosopher Louis Althusser, introduced the term "theoretical antihumanism" to attack both humanism and socialism currents leaning towards humanism eschewing more structural or formal interpretation of Marx. For Althusser, early writings of Marx resonated with humanistic idealism of Hegel, Kant and Feuerbach but in 1845, according to Althusser, Marx took a radical turn towards scientific socialism, rejecting concepts such as the essence of man  .
