As the po liti cal crisis of the early 1930s accelerated, however, Rougier's attentions began to drift away from neopositivist critiques of theology and toward what he perceived to be contemporary "mystiques," or doctrines that "one would not know how to demonstrate by reason or to ground in experience, but that one accepts blindly for irrational motives." He viewed this endeavor as very much connected to his previous philosophical project: an attempt to identify logical fallacies that had permeated the pop u lar imagination, and in doing so to rescue and demarcate the proper spheres of scientifi c inquiry.
