Pan-atheism
Pan-atheism is a pseudo-pantheism that is akin to marxist materialism and to scientific reductionism and that does not believe in any internal meaning and in any inherent purpose to human life and to the cosmos.Pan-atheism is a "pseudo-pantheism" because "pan-atheists" do not believe in the actual definiton of pantheism which means "All in God and God in All"; rather their beliefs are better encapsulated by the definition: "All is Nature" and "Nature is All".
