Leonardo da Vinci
  • Marriage is like putting your hand into a bag of snakes in the hope of pulling out an eel.

  • Why does the eye see a thing more clearly in dreams than the imagination when awake?

  • Anyone who conducts an argument by appealing to authority is not using his intelligence he is just using his memory.

  • All our knowledge has its origins in our perceptions.

  • Where there is shouting, there is no true knowledge.
