Aristotle on Friendship

A true friend is a single soul dwelling in two bodies.

Aristotle devoted more space to friendship in his ethics than almost any other topic. He believed that no one would choose to live without friends, even if they had everything else. For Aristotle, true friendship is one of life's greatest goods — and it is built on shared character, not convenience.

Key Teachings

Three Kinds of Friendship

Aristotle identified three types of friendship: those based on utility, those based on pleasure, and those based on shared virtue. Only the third kind — rooted in mutual respect and good character — is deep and lasting.

Think about your closest friendships: are they built on convenience, entertainment, or genuine mutual respect?

Friendship Requires Time

Aristotle said you cannot know a person until you have 'eaten a measure of salt together.' True friendship develops slowly through shared experiences, honest conversations, and consistent care over years, not days.

Invest time in a friendship you value: reach out to a close friend this week just to connect, with no agenda.

Friends Make You Better

For Aristotle, the best friendships are those that bring out the best in each person. A true friend challenges you to grow, celebrates your virtues, and gently holds you accountable when you fall short.

Ask yourself whether your closest relationships are helping you grow, and look for ways to support your friends' growth in return.

In Aristotle's Words

Without friends, no one would want to live, even if he had all other goods. — Aristotle, Nicomachean Ethics
