Aristotle
(page 2)

All virtue is summed up in dealing justly.

Dignity consists not in possessing honors, but in the consciousness that we deserve them.

Education is the best provision for old age.

Even when laws have been written down, they ought not always to remain unaltered.

Happiness depends upon ourselves.

He who has overcome his fears will truly be free.

He who is unable to live in society, or who has no need because he is sufficient for himself, must be either a beast or a god.

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.

In all things of nature there is something of the marvelous.

It is in justice that the ordering of society is centered.

Misfortune shows those who are not really friends.

Nature does nothing uselessly.

One swallow does not make a summer, neither does one fine day; similarly one day or brief time of happiness does not make a person entirely happy.

Plato is dear to me, but dearer still is truth.

Pleasure in the job puts perfection in the work.

Poverty is the parent of revolution and crime.

The gods too are fond of a joke.

The moral virtues, then, are produced in us neither by nature nor against nature. Nature, indeed, prepares in us the ground for their reception, but their complete formation is the product of habit.

The only stable state is the one in which all men are equal before the law.

Time crumbles things; everything grows old under the power of Time and is forgotten through the lapse of Time.
