According to the sentence Audiatur et altera pars ("one should listen to the other side, too") he wants to counterbalance the gigantic ascendence of the existing glorification of Christianity.
In the introduction to the complete works, which is the beginning of the first volume, Deschner explains his intention by starting with what is not to be found in his work: an answer to the question "What is Christianity good for?". According to the sentence Audiatur et altera pars ("one should listen to the other side, too") he wants to counterbalance the gigantic ascendence of the existing glorification of Christianity. Also, he does not want to write about the alleged or - exceptionally - really positive effects of Christianity. Instead, he wants to demonstrate that the advocates of a primary moral instance not only partially but permanently failed their own ideals.
