Emmanuel Kant was a German philosopher and a central figure for modern philosophy. Here are some of his most famous quotes:
Science is organized knowledge. Wisdom is organized life.
Experience without theory is blind, but theory without experience is mere intellectual play.
Happiness is not an ideal of reason, but of imagination.
Always recognize that human individuals are ends, and do not use them as means to your end.
I had therefore to remove knowledge, in order to make room for belief.
May you live your life as if the maxim of your actions were to become universal law.
Religion is the recognition of all our duties as divine commands.
From such crooked wood as that which man is made of, nothing straight can be fashioned.
Nothing is divine but what is agreeable to reason.
All thought must, directly or indirectly, by way of certain characters, relate ultimately to intuitions, and therefore, with us, to sensibility, because in no other way can an object be given to us.
