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

Comedy aims at representing men as worse, Tragedy as better than in actual life.

Aristotle
A man's happiness consists in the free exercise of his highest faculties.
Aristotle

Courage is the first of human qualities because it is the quality which guarantees the others.

Aristotle
Every community is an association of some kind and every community is established with a view to some good; for everyone always acts in order to obtain that which they think good. But, if all communities aim at some good, the state or political community, which is the highest of all, and which embraces all the rest, aims at good in a greater degree than any other, and at the highest good.
Aristotle

Of old, the demagogue was also a general, and then democracies changed into tyrannies. Most of the ancient tyrants were originally demagogues. They are not so now, but they were then; and the reason is that they were generals and not orators, for oratory had not yet come into fashion.

Aristotle
The best friend is the man who in wishing me well wishes it for my sake.
Aristotle

Life is only meaningful when we are striving for a goal .

Aristotle
A friend is simply one soul in two bodies.
Aristotle

If 'bounded by a surface' is the definition of body there cannot be an infinite body either intelligible or sensible.

Aristotle
If what was said in the Ethics is true, that the happy life is the life according to virtue lived without impediment, and that virtue is a mean, then the life which is in a mean, and in a mean attainable by every one, must be the best. And the same principles of virtue and vice are characteristic of cities and of constitutions; for the constitution is in a figure the life of the city.
