In some rare cases, a friendship between two people benefits both of them, and what’s more, in some rarer cases, it benefits both of them equally.

Some of our friends are our friends only because we used to be friends.

The pleasure or the benefit that the object of our deed derives from it is every now and then greater or even more important than the one we derive from the deed.

Every single good person is a good person for their own sake, not for the sake of humanity, not even for the sake of another human being.

Females and boys are the only creatures that propose others for friendship. As for the rest of us, friendship sort of just happens.

No single bad person regards themselves as a bad person.
