Aristotle

We must become just be doing just acts.

The excellence of a thing is related to its proper function.

Human beings are curious by nature.

To be conscious that we are perceiving or thinking is to be conscious of our own existence.

One who faces and who fears the right things and from the right motive, in the right way and at the right time, posseses character worthy of our trust and admiration.

Our characters are the result of our conduct.

Between friends there is no need of justice.

Character is that which reveals moral purpose, exposing the class of things a man chooses and avoids.

Virtue means doing the right thing, in relation to the right person, at the right time, to the right extent, in the right manner, and for the right purpose. Thus, to give money away is quite a simple task, but for the act to be virtuous, the donor must give to the right person, for the right purpose, in the right amount, in the right manner, and at the right time.

A true disciple shows his appreciation by reaching further than his teacher.

A vivid image compels the whole body to follow.

All friendly feelings toward others come from the friendly feelings a person has for himself.

Justice is the loveliest and health is the best. but the sweetest to obtain is the heart's desire.

But since there is but one aim for the entire state, it follows that education must be one and the same for all, and that the responsibility for it must be a public one, not the private affair which it now is, each man looking after his own children and teaching them privately whatever private curriculum he thinks they ought to study.

Justice therefore demands that no one should do more ruling than being ruled, but that all should have their turn.

So it is clear that the search for what is just is a search for the mean; for the law is the mean.

For knowing is spoken of in three ways: it may be either universal knowledge or knowledge proper to the matter in hand or actualising such knowledge; consequently three kinds of error also are possible.

The man who is truly good and wise will bear with dignity whatever fortune sends, and will always make the best of his circumstances.

He who has conferred a benefit on anyone from motives of love or honor will feel pain, if he sees that the benefit is received without gratitude.

Neither old people nor sour people seem to make friends easily; for there is little that is pleasant in them.

The best way to teach morality is to make it a habit with children.
