Friedrich Nietzsche

Not necessity, not desire – no, the love of power is the demon of men. Let them have everything – health, food, a place to live, entertainment – they are and remain unhappy and low-spirited: for the demon waits and waits and will be satisfied.

What do I care about the purring of one who cannot love, like the cat?

There is not enough love and goodness in the world to permit giving any of it away to imaginary beings.

Today I love myself as I love my god: who could charge me with a sin today? I know only sins against my god but who knows my god?

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

Love is blind friendship closes its eyes.

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

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.
