Aristotle was a Greek Philosopher and a very educated man. He was a pupil of Plato's and was the founder of the Lyceum. His view on all subjects was teleological. He recognized purposes apart from and greater then the will of the individual human being. He gained much of his wisdom and knowledge through his experiences and observations.
Aristotle believed that human happiness was the reaction of fulfilling human potentialities. These potentialities can be identified by rational choice, practical judgment, and recognition of the value of choosing the mean instead of extremes. In his view, matter existed to achieve an end and it developed until it achieved its form. There was constant development from matter to form, from potential to actual. Therefore human primitive instincts could be seen as the matter out of which the human's potential as a political being could be realized. Aristotle argued that the polis was a natural growth and that human beings was by nature "an animal who lives in a polis." The polis made humans more dependant to themselves and allowed them to achieve the highest level of there potential. He believed that the purpose of the polis was moral. According to Aristotle, "The end of the state is the good life and for the life lived a life of virtue and morality."
True freedom consisted in ruling and being ruled in turn according to the agreed-on laws of the community. Humans have the free right and ability to distinguish good from evil and right from wrong. Aristotle observed that men in public life outside the home obtained by the dangerous disorder caused by the desire for power was disastrous. The inevitable will for power caused many disagreements which later ended up in war. Only free men were allowed to obtain political status. Women, children and slaves were given very little or no political power.
Human beings are capable of many things.
