Marxism.

The Marxist combination of materialism and determinism is fatally anti-humanistic. It denies a consciousness, a mind, that is independent of material conditions and class relations. It denies a will and volition that are capable of shaping the course of history. It denies an individuality that is not reducible to class. It denies both the idea and the reality of freedom, a freedom that is something more than the "bourgeois" freedom to buy and sell. It denies a morality that transcends class interests. And it denies the spirituality of man.
