Friedrich Nietzsche

Success has always been a great liar.

There is always some madness in love. But there is also always some reason in madness.

The man of knowledge must be able not only to love his enemies but also to hate his friends.

Whatever is done for love always occurs beyond good and evil.

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

A pair of powerful spectacles has sometimes sufficed to cure a person in love.

We love life, not because we are used to living but because we are used to loving.

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.

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

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