The personal or biographical variables are, no doubt, the most broadly highlighted, sometimes even with the precise faults that A. Freud is blamed for: a radical reductionism and a truly extreme psychologism. In parallel, but with more difficulty, a distinction could and should be established between what within Freudian texts regarding religion is properly psychoanalytical and what comes from Freud’s biography and personal options. Psychoanalysis, then, becomes a road to inner purification from which faith can then be authenticated. The influence of Schopenhauer’s pessimism also had an impact on Freudian thought with a series of permeations that later psychoanalysis has been rightly obliged to question. Man’s image has been deeply transformed since the psychoanalytical discoveries, and the world of values has undergone a series of important re-examinations. Theology, in Spain in particular, seems to have neglected paying attention to psychoanalytical discoveries.
