About Immanuel Kant

1724 – 1804

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

“Have courage to use your own understanding!”

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

“It is precisely in knowing its limits that philosophy consists.”

“They who know the truth are not equal to those who love it, and they who love it are not equal to those who delight in it.”

“Knowledge, that tendeth but to satisfaction, is but as a courtesan, which is for pleasure, and not for fruit or generation.”

“If a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts, he shall end in certainties.”

“That which is most excellent, and is most to be desired by all happy, honest and healthy-minded men, is dignified leisure.”

“The consciousness of life is higher than life, the knowledge of the laws of happiness is higher than happiness.”

“Knowledge is not happiness, and science but an exchange of ignorance for that which is another kind of ignorance.”
