Moreover, one should so respect a friend's presence that he dare not perform anything shameful or speak any unbecoming word, since any fault so reflects on a friend that the friend not only blushes and grieves inwardly but also reproaches himself with what he sees or hears, as if he had committed the sin himself.

No medicine is more valuable , none more efficacious, none better suited to the cure of our temporal ills than a friend to whom we may turn for consolation in time of trouble, and with whom we may share happiness in time of joy.

The reward of friendship is itself. The man who hopes for anything else does not understand what true friendship is.

Friendship is that virtue by which spirits are bound by ties of love and sweetness and out of many are made one.
