Friedrich Nietzsche

The desire to annoy no one, to harm no one, can equally well be the sign of a just as of an anxious disposition.

Rejoicing in our joy, not suffering over our suffering, makes someone a friend.

There are slavish souls who carry their appreciation for favors done them so far that they strangle themselves with the rope of gratitude.

Shared joys make a friend, not shared sufferings.

The essence of all beautiful art, all great art, is gratitude.

There is more wisdom in your body than in your deepest philosophy.

Does wisdom perhaps appear on the earth as a raven which is inspired by the smell of carrion?

War has always been the grand sagacity of every spirit which has grown too inward and too profound; its curative power lies even in the wounds one receives.

Love is blind; friendship closes its eyes.

It is not a lack of love, but a lack of friendship that makes unhappy marriages.

Judgments, value judgments concerning life, for or against, can in the last resort never be true: they possess value only as symptoms, they come into consideration only as symptoms - in themselves such judgments are stupidities.

A woman may very well form a friendship with a man, but for this to endure, it must be assisted by a little physical antipathy.
