What does Atheism transcendentalize?

... it has also been shown by Alister McGrath in his book on atheism that if you do not have religion to transcendentalize things, you end up transcendentalizing something else. In other words, the act of making something out to be of transcendental importance is not exclusively a function of religion. It may be a function of human desire to control. In the twentieth century, the powerful movements of Nazism and Stalinism were not religiously driven. Some in the Nazi party laid claim to their reconstruction of Christianity, but the purpose was to domesticate Christianity and harness its energies. In reality, what drove the two movements-Nazism and Stalinism-were were distinct visions of reality: on the one hand, the transcendentalizing of ethnicity, a sense of intrinsic Aryan superiority, a hate-filled blaming of Jews and of the Treaty of Versailles; on the other hand, a transcendentalizing of the state grounded in Marxist social and economic theory. So it is not as if religion poisons everything while everything else is good. The century characterized by the greatest bloodshed, the twentieth century, generated most of its violence in movements that were distinctly anti-religious. The world did not lose one-third of the population of Cambodia because of Christianity but because of communism.

Comment: From D. A. Carson. God Who Is There, The: Finding Your Place in God's Story (pp. 183-184). Kindle Edition. I hypothesize that atheism primarily transcendentalizes science.
