“All people are good at making distinctions about the things they are acquainted with, and each is a good judge of those things. Therefore, good judgment goes along with the way each one is educated, and the one who has been educated about everything has it in an unqualified way. For this reason, it is not appropriate for a young person to be a student of politics, since the young are inexperienced in the actions of life, while these are the things about which politics speaks and from which it reasons. Also, since the young are apt to follow their impulses, they would hear such discourses without purpose or benefit, since their end is not knowing but action. And it makes no difference whether one is young in age or immature in character, for the deficiency doesn’t come from the time, but from living in accord with feeling and following every impulse. For knowledge comes to such people without profit, as it does to those who lack self-restraint; but to those who keep their desires in proportion and act in that way, knowing about these things would be of great benefit.”

This quote comes from one of the first three chapters in Book One of Aristotle’s Nicomachean Ethics, with which Aristotle intends to set as a prelude to his discourse regarding how it ought to be received as well as what the task is that “we have set before ourselves.”
