Friendship is a thing most necessary to life, since without friends no one would choose to live, though possessed of all other advantages.
We should behave to our friends as we would wish our friends behave to us
Friends are an aid to the young, to guard them from error; to the elderly, to attend to their wants and to supplement their failing power of action; to those in the prime of life, to assist them to noble deeds.
Perfect friendship is the friendship of men who are good, and alike in excellence; for these wish well alike to each other qua good, and they are good in themselves.
Friendship is communion.
Without friends no one would choose to live, though he had all other goods.
Friendship is essentially a partnership.
Misfortune shows those who are not really friends.
In poverty and other misfortunes of life, true friends are a sure refuge. The young they keep out of mischief; to the old they are a comfort and aid in their weakness, and those in the prime of life they incite to noble deeds.
For though we love both the truth and our friends, piety requires us to honor the truth first.
When people are friends, they have no need of justice, but when they are just, they need friendship in addition.
A friend is a second self.
Friendship is a single soul dwelling in two bodies.
A friend to all is a friend to none.
