The history of the construction of Psychology is on, at each historical moment, to the requirements of knowledge of the humanity, to the too much areas of the human knowledge and to the new challenges placed for the economic and social reality and the insacivel necessity of the man to understand itself exactly. Psychology enters the Greeks the history of the human thought has a golden moment in the Antiquity, between the Greeks, particularly in the period of 700 B.C. until the domination Roman, to the eves of the Christian age. It is between the Greek philosophers whom the first attempt appears systemize a Psychology. The proper term psychology comes of the Greek psych (soul), and of logos (reason), therefore psychology means ' ' study of alma' '. The philosophers daily pay-socrticos were worried in defining the relation of the man with the world through the perception. He had an opposition enters the idealists (the idea forms the world) and the materialists (the substance that forms the world already is given stops perception). Scrates claimed that the main characteristic human being was the reason.
When defining reason peculiarity of the man or as essence, it opened a way that very would be explored by Psychology. Plato looked for to define one ' ' lugar' ' for reason in our proper body. It defined this place as being the head, where if it finds the soul of the man. When somebody died, the substance (the body) disappeared, but the soul was free to occupy another body. Aristotle was innovative or claims that the soul and the body could not be dissociados. For it, psych would be the active principle of the life. Everything what it grows, if reproduces and if it feeds possesss its proper soul. Of this form the vegetables, the animals and the men would have soul. The first ones would have a vegetative soul, the seconds also and still the sensitive soul.
