“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.”

“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)”

“Une politique valable ne peut faire un pas sans rendre hommage à la morale.”

“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.”

“Two things fill the mind with ever new and increasing admiration and awe, the oftener and more steadily we reflect on them: the starry heavens above and the moral law within.”
