The theme of the truth in Freud is developed as of his writing on Moses and monotheism. There are questions on the effects of his search for the truth, which is based on his choice for science. There are calls to Lacan's reference to a "passion for the truth" in Freud, with the intent to include his category of the real in the discussion. It is concluded by the association of the results presented by Freud in his work, which are taken in their political dimension, and the experience in psychoanalysis itself.
