Cf. Aristotle's Politics translated (full text)
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.
In an early dialogue of Plato's, the Protagoras, Socrates asks Protagoras why it is not as easy to find teachers of virtue as it is to find teachers of swordsmanship, riding, or any other art. Protagoras' answer is that there are no special teachers of virtue, because virtue is taught by the whole community. Plato and Aristotle both accept the view of moral education implied in this answer. In a passage of the Republic (492 b) Plato repudiates the notion that the sophists have a corrupting moral influence upon young men. The public themselves, he says, are the real sophists and the most complete and thorough educators. No private education can hold out against the irresistible force of public opinion and the ordinary moral standards of society. But that makes it all the more essential that public opinion and social environment should not be left to grow up at haphazard as they ordinarily do, but should be made by the wise legislator the expression of the good and be informed in all their details by his knowledge. The legislator is the only possible teacher of virtue.
