The Politics of Aristotle is the second part of a treatise of which the Ethics is the first part. It looks back to the Ethics as the Ethics looks forward to the Politics. For Aristotle did not separate, as we are inclined to do, the spheres of the statesman and the moralist. In the Ethics  he has described the character necessary for the good life, but that life is for him essentially to be lived in society, and when in the last chapters of the Ethics he comes to the practical application of his inquiries, that finds expression not in moral exhortations addressed to the individual but in a description of the legislative opportunities of the statesman. It is the legislator's task to frame a society which shall make the good life possible. Politics for Aristotle is not a struggle between individuals or classes for power, nor a device for getting done such elementary tasks as the maintenance of order and security without too great encroachments on individual liberty. The state is "a community of well-being in families and aggregations of families for the sake of a perfect and self-sufficing life." The legislator is a craftsman whose material is society and whose aim is the good life.
