About Immanuel Kant

1724 – 1804

German philosopher of the Enlightenment, author of the "Critique of Pure Reason".

“Have courage to use your own understanding!”

“Morality is not properly the doctrine of how we may make ourselves happy, but how we may make ourselves worthy of happiness.”

“Thoughts without content are empty, intuitions without concepts are blind.”

“A little flesh, a little breath, and a Reason to rule all—that is myself.”

“Knowing others is intelligence; knowing yourself is true wisdom.”

“One must learn to know oneself before knowing anything else.”

“Wouldst thou other men know, look thou within thine own heart.”

“I could give you no advice but this: to go into yourself and to explore the depths where your life wells forth.”

“The basic stimulus to the intelligence is doubt, a feeling that the meaning of an experience is not self-evident.”
