Everybody knows that Aristotle holds that man is the alone animal which is endowed with logos. But, too many people think that for this reason man is the only one political animal. The author argues against this illusory evidence. If man is truely the only one animal which is endowed with logos, this fact does not involve that he is a political animal. Worse that man is the only one to be an authentic political animal. But, giving to the others animals their due part does not involve that Aristotle was the father of the sociobiology.
