A man ought not to be a good judge until he be old; because he ought not have acquired a knowledge of what injustice is, until his understanding has arrived at maturity: not apprehending its nature from a consideration of its existence in himself; but having contemplated it distinct from his own nature in that of others, for a long time, until he shall perceive what an evil it is, not from his own experience and its effects within himself, but from his observations of them as resulting in others. Such a one were indeed an honourable judge, and a good; for he who has a good mind, is good. But that judge who is considered so wise, who having himself committed great injustice, is supposed to be qualified for the detection of it in others, and who is quick to suspect, appears keen, indeed, as long as he associates with those who resemble him; because, deriving experience from the example afforded by a consideration of his own conduct and character, he acts with caution; but when he associates with men of universal experience and real virtue, he exposes the defects resulting from such experience as he possesses, by distrusting men unreasonably and mistaking true virtue, having no example of it within himself with which to compare the appearances manifested in others: yet, such a one finding more associates who are virtuous than such as are wise, necessarily appears, both to himself and others, rather to be wise than foolish.--But we ought rather to search for a wise and good judge; one who has examples within himself of that upon which he is to pronounce.--C. iii.

On this Shelley makes the following remarks--
