"Why, that all those mercenary individuals, whom the many call Sophists and whom they deem to be their adversaries, do, in fact, teach nothing but the opinion of the many, that is to say, the opinions of their assemblies; and this is their wisdom." "Good he pronounces to be that in which the beast delights and evil to be that which he dislikes; and he can give no other account of them except that the just and noble are the necessary, having never himself seen, and having no power of explaining to others the nature of either, or the difference between them, which is immense." "And in what way does he who thinks that wisdom is the discernment of the tempers and tastes of the motley multitude, whether in painting or music, or, finally, in politics, differ from him whom I have been describing? For when a man consorts with the many, and exhibits to them his poem or other work of art or the service which he has done the State, making them his judges when he is not obliged, the so-called necessity of Diomede will oblige him to produce whatever they praise." "The poet is like a painter who, as we have already observed, will make a likeness of a cobbler though he understands nothing of cobbling; and his picture is good enough for those who know no more than he does, and judge only by colors and figures." "...the excellence or beauty or truth of every structure, animate or inanimate, and of every action of man, is relative to the use for which nature or the artist has intended them." "...the imitative poet who aims at being popular is not by nature made, nor is his art intended, to please or to affect the rational principle in the soul; but he will prefer the passionate and fitful temper, which is easily imitated." "Until philosophers are kings, or the kings and princes of this world have the spirit and power of philosophy, and political greatness and wisdom meet in one, and those commoner natures who pursue either to the exclusion of the other are compelled to stand aside, cities will never have rest from their evils -- no, nor the human race, as I believe -- and then only will this our State have a possibility of life and behold the light of day." "The judge should not be young; he should have learned to know evil, not from his own soul, but from late and long observation of the nature of evil in others: knowledge should be his guide, not personal experience." "Bodily exercise, when compulsory, does no harm to the body; but knowledge which is acquired under compulsion obtains no hold on the mind." - Plato, The Republic Plato-related resources and texts on the Internet: http://PhilosophySearch.com/search/Philosophers/Plato/
