Civilization, sexuality and entropy in Freud's thought

This article intends to offer, in an introductory way, a reflection in order to build an interpretation of the Sigmund Freud's thought, orchestrating notions such as the ones of progress of civilization, which would be his philosophy of history; an investigation on his conceptions about "human nature"; culminating in a brief reflection on some points of philosophy of nature that underlies his thought. We anticipate that we recognize in the latter, characteristics assimilated by analogy to the entropy concept of modern physics. Among other features, such as compared and methodological reference with some of Kant's theses about the same notions, we also present in a short way two metapsychological aspects of Freudian theory on human sexuality, the biological and physiological, both aiming to give support to the reflections on the sense of finality.
