We can observe great philosophers as, Scrates, Plato, Aristotle, Saint Augustin, Toms de Aquino, Hobbes, Hume, Hegel, Kant, Brgson, Heidegger, Habermas, each one its way, searching the establishment of codes of ethics valid universally. Having the Ethics as science of the behavior, we can observe two conceptions: ‘ ‘ science that deals with the end that must guide the behavior of the men and the half ones to reach such end. It is the ideal formulated and pursued for the man for its nature and essncia.’ ‘ ‘ ‘ science that deals with the furniture of the behavior human being and looks for to determine this furniture being aimed at to direct the proper behavior. The desire of sobrevivncia.’ is leagued to it; ‘ ). In the first conception we see Scrates as precursory of the Ethics in the Ocidente, Plato that dealt with the ethics of the virtues in ‘ ‘ The Repblica’ ‘ , Aristotle who deals with the intention of the behavior human being to search the happiness from its rational nature. Hegel dealt with the objective of the behavior human being detaching the State as the reality in which the behavior finds integration and perfection, treating the Ethics as the legal philosophy.
In its second conception, we see Prdico that contemplates in them its words: ‘ ‘ If to desire to be honored by a city you must be useful to cidade’ ‘. (PRDICO. The Hours, the original was lost, but its essence meets in Memorabilia) Protgoras nailed to the mutual respect and justice as necessary conditions to the survival of the Man; Kant pointed out the Ethics in the world of the pure reason, in which the rational beings searched to firm this world preventing the individualizados interests and pursuing the good. Benthan defended the behavior of the Man with being determined for the expectation of the pleasure or pain, being this the only possible reason of the action.
