The aim of the wise is not to secure pleasure, but to avoid pain.

Those who educate children well are more to be honored than they who produce them; for these only gave them life, those the art of living well.

The greatest virtues are those which are most useful to other persons.

We make war that we may live in peace.

The least initial deviation from the truth is multiplied later a thousandfold.

It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied.

To perceive is to suffer.

The law is reason free from passion.

All human actions have one or more of these seven causes: chance, nature, compulsion, habit, reason, passion, and desire.

The worst form of inequality is to try to make unequal things equal.

Some men are born slaves, and others are born to rule.

Women are defective by nature.

The state comes into existence for the sake of life and continues to exist for the sake of the good life.

All paid jobs absorb and degrade the mind.

From the hour of their birth, some are marked out for subjection, others for rule.

The slave is wholly lacking the deliberative element; the female has it but it lacks authority; the child has it but it is incomplete.

For the male is by nature superior, and the female inferior; and the one rules, and the other is ruled; this principle, of necessity, extends to all mankind.

Among barbarians the female and the slave have the same status.

The slave is a living tool.
