“For sure, even with the best will, the modern person seems generally unable to imagine how large a significance those components of our consciousness rooted in religious beliefs have actually had upon culture, national character, and the organization of life. Nevertheless, it can not be, of course, the intention here to set a one-sided spiritualistic analysis of the causes of culture and history in place of an equally one-sided “materialistic” analysis. Both are equally possible. Historical truth, however, is served equally little if either of these analyses claims to be the conclusion of an investigation rather than its preparatory stage.”
