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.

Aristotle’s quote defines perfect friendship as a bond between individuals who are good and share similar qualities of excellence. He argues that true friendship is built on mutual respect and admiration for each other's virtuous characteristics. In such a friendship, both individuals wish the best for one another, not for selfish reasons, but because they recognize and value each other's inherent goodness. This type of friendship is deeply rooted in ethical and moral alignment, where the connection is formed not merely by shared interests or convenience, but by mutual commitment to excellence.

The idea of friendship in this context is one that transcends superficial connections. Aristotle emphasizes that these friendships are grounded in the recognition of each other's virtue. Such friends care for each other not because of what they can gain personally, but because they see the other person as an individual who is equally dedicated to being good. This deep understanding and admiration for each other’s character forms the foundation of a perfect friendship.

Moreover, Aristotle notes that these friendships are formed between people who are good in themselves—that is, individuals who possess and cultivate virtues like honesty, integrity, and generosity. These individuals share a common goal of living a virtuous life, which makes their friendship not only fulfilling but also a source of mutual growth and support. The friendship is not based on convenience, but on a shared commitment to excellence and moral goodness.

Originating from Aristotle, one of the most influential philosophers in Western thought, this quote reflects his views on ethics and the nature of relationships. In his work Nicomachean Ethics, Aristotle explores the concept of friendship in detail, distinguishing between different types of friendships—those based on utility, pleasure, and virtue. The quote highlights his belief that the highest form of friendship is one that is based on mutual virtue and shared excellence, providing an enduring and meaningful connection between individuals.
