Questions related to religious faith have once again become an object of speculation in contemporary culture. What is meant here is not speculation in the ordinary sense of the word, a way of thinking which we are accustomed to equating with an unconscientious attitude toward someone else's opinion. The speculation of faith exists in the most «natural» intellectual sense, even according to the logic of which the sphere of human existence is measured exclusively by the narratives of a formally scientific approach. In other words, faith is understood as a sort of human quality that it wouldn't be a bad idea to verify by means of the algebra of rational discourse. Tertullian's «I believe, because it is absurd» is subjected not simply to doubt, but to absolute denial. Our contemporaries often don't even suspect that religious faith exists, in a natural, primordial, moral and spiritual sense, and that it cannot be examined, even by the most perfect intellectual apparatus.
