A friend is one soul abiding in two bodies.
Stagira, Greece
All men by nature desire to know.
In every systematic inquiry where there are first principles, or causes, or elements, knowledge and science result from acquiring knowledge of these.
We are what we repeatedly do. Excellence, then, is not an act, but a habit.
Misfortune shows those who are not really friends.
I am not an Athenian or a Greek, but a citizen of the world.
It is not a lack of love, but a lack of friendship that makes unhappy marriages.
