Why Friendship Is Essential to a Good Life

We have never had so many ways of connecting with other people, and yet so few close friends.
Many of us have hundreds or even thousands of online contacts, but no one we could call in the middle of the night. We move cities, change jobs, change partners, and change phones without thinking twice, and our friendships often prove just as disposable.
Aristotle would have regarded this not merely as a social problem, but as a human tragedy.
‘Without friends,’ he writes in the Nicomachean Ethics, ‘no one would choose to live, though he had all other goods.’
It is a remarkable claim.
Most of us think that, given enough money, success, health, freedom, and comfort, we could muddle along well enough on our own. Aristotle thought otherwise. Friendship is not simply one of life’s pleasures. It is one of its necessities.
Why We Need Friends
The ancient Greeks had several words for love, including eros for passionate or romantic love, and philia (the root of ‘bibliophile’ and ‘anglophile’) for friendship.
For Aristotle, philia is a virtue which is ‘most necessary with a view to living … for without friends no one would choose to live, though he had all other goods.’
Philia underpins not only personal happiness but the very health of the state. Friendship fosters trust, cooperation, generosity, forbearance, and even justice—for when friendship exists, justice is scarcely needed.
But friendship is not simply for enjoying and getting along. In its highest form, it is a vehicle of virtue, helping us to become better people.
The Three Forms of Friendship
Aristotle begins with a broad or minimal concept of philia. For one person to be friends with another, it is necessary, simply, ‘that [they] bear good will to each other, without this escaping their notice’.
A person may bear goodwill to another for one of three reasons: that they are useful; that they are pleasant; or that they are good—that is, rational and virtuous.
Friendships of utility are based on mutual advantage. We enjoy one another’s company because each has something to offer the other. Such friendships are common in business, politics, and everyday life, and there is nothing wrong with them. But remove the advantage, and they usually disappear.
Friendships of pleasure are based on enjoyment. We like another person’s wit, humour, charm, or shared interests. These friendships are especially common among the young, whose lives are often governed more by feeling than by settled character. They, too, tend to fade as tastes and circumstances change.
The highest form of friendship is based not on usefulness or pleasure, but on virtue. ‘Perfect friendship’, says Aristotle, is ‘the friendship of men who are good, and alike in virtue.’
Perfect friends are drawn to each other not because they expect anything in return, but because they genuinely admire and value one another’s character. They love their friend not for what he has or provides, but for who he is.
Now those who wish well to their friends for their sake are most truly friends; for they do this by reason of their nature and not incidentally; therefore their friendship lasts as long as they are good—and goodness is an enduring thing … And such a friendship is as might be expected permanent, since there meet in it in all the qualities that friends should have.
Another Self
A perfect friend, says Aristotle, is ‘another self’.
This does not mean someone who merely resembles us or always agrees with us. It means someone who cares enough, or is noble enough, to disagree with us and challenge us.
A true friend shares our deepest values, but also helps us to live up to them. We become better not by admiring virtue from afar, but by practising it together. Friendship is not merely the reward of virtue; it is one of the principal ways in which virtue is cultivated.
Every act of friendship is also an exercise in virtue. In being patient with our friend, we become more patient ourselves. In speaking honestly, we become more honest. In encouraging what is best in another person, we strengthen what is best in ourselves. Our good and their good are no longer competing like fishmongers: each one’s happiness adds to that of the other. We become, in the deepest sense, another self.
We may find an illustration of this ideal in Plato’s Phaedrus. Socrates and Phaedrus spend an afternoon walking in the Attic countryside while reflecting on the soul, love, and the art of persuasion. Their friendship is grounded not merely in pleasure, but in a shared pursuit of truth. At the end of their conversation, Phaedrus responds to Socrates’ prayer with the simple request: ‘Ask the same for me, for friends should have all things in common.’ Whether or not Aristotle had this dialogue in mind, it beautifully embodies his conception of perfect friendship.
Why Friendship Is Rare
Unfortunately, perfect friendship is uncommon.
First, it requires good character, and good character is itself uncommon. Second, it demands something that has always been scarce and may never have been scarcer than today: time.
Friendship cannot be hurried.
People only come to know one another by sharing experiences, surviving disappointments, forgiving offences, and gradually learning that they can be trusted. Like character itself, friendship grows slowly.
We live in a culture that prizes speed, convenience, novelty, and consumer choice. Relationships, like everything else, are expected to fit around our schedules and satisfy our needs. Friendship asks something very different of us. It requires attention, loyalty, respect, forbearance, and sometimes considerable sacrifice.
The Courage to Be Known
There is another difficulty.
Many of us have become so unaccustomed to genuine friendship that, when we encounter its possibility, we instinctively retreat from it.
A true friend is not simply someone who makes us feel better. He knows us. He sees through our pretences. He notices when we deceive ourselves. He quietly expects us to become better than we are.
That can be deeply unsettling.
We often say that we want people to accept us exactly as we are. Aristotle might have replied that a friend accepts us as we are while refusing to leave us there.
Perhaps that is why perfect friendship is so rare. It demands not only affection, but humility; not only loyalty, but the willingness to be changed.
Nowadays, it is all too easy to retreat into comfortable mediocrity.
Friendship and Happiness
Throughout the Nicomachean Ethics, Aristotle argues that happiness lies not in pleasure or success, but in living according to reason and virtue.
Friendship is one of the principal ways in which this becomes possible.
A good friend encourages what is best in us, restrains what is worst, and accompanies us in the long and difficult work of becoming the person we are capable of being. If we abandon a true friend, really, it is our own self that we are abandoning.
We tend to think of friendship as one of life’s pleasures.
Aristotle thought of it as one of life’s disciplines.
A good friend does not simply make us happier.
He helps us become better and bigger.
