There are branches of learning and education which we must study merely with a view to leisure spent in intellectual activity, and these are to be valued for their own sake; whereas those kinds of knowledge which are useful in business are to be deemed necessary, and exist for the sake of other things.

Aristotle

Happiness is the meaning and the purpose of life, the whole aim and end of human existence.

Aristotle
Knowing what is right does not make a sagacious man.
Aristotle

The greatest thing in style is to have a command of metaphor.

Aristotle
Humor is the only test of gravity, and gravity of humor; for a subject which will not bear raillery is suspicious, and a jest which will not bear serious examination is false wit.
Aristotle

The ultimate value of life depends upon awareness and the power of contemplation rather than upon mere survival.

Aristotle
Life is full of chances and changes, and the most prosperous of men may in the evening of his days meet with great misfortunes.
Aristotle

People do not naturally become morally excellent or practically wise. They become so, if at all, only as the result of lifelong personal and community effort.

Aristotle
No great mind has ever existed without a touch of madness.
Aristotle

Our virtues are voluntary (and in fact we are in a sense ourselves partly the cause of our moral dispositions, and it is our having a certain character that makes us set up an end of a certain kind), it follows that our vices are voluntary also; they are voluntary in the same manner as our virtues.

Aristotle
What the statesman is most anxious to produce is a certain moral character in his fellow citizens, namely a disposition to virtue and the performance of virtuous actions.
