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

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

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

  • Love is blind friendship closes its eyes.

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