“An action, to have moral worth, must be done from duty.”

“Have the courage to use your own reason- That is the motto of enlightenment. "Foundations of the Metaphysics of Morals" (1785)”

“Without man and his potential for moral progress, the whole of reality would be a mere wilderness, a thing in vain, and have no final purpose.”

“Man, and in general every rational being, exists as an end in himself, not merely as a means for arbitrary use by this or that will: he must in all his actions, whether they are directed to himself or to other rational beings, always be viewed at the same time as an end.”

“The death of dogma is the birth of morality.”

“True politics cannot take a single step without first paying homage to morals, and while politics itself is a difficult art, its combination with morals is no art at all; for morals cuts the Gordian knot which politics cannot solve as soon as the two are in conflict.”

“For peace to reign on Earth, humans must evolve into new beings who have learned to see the whole first.”
