Immanuel Kant

“Have courage to use your own understanding!”

“Enlightenment is man's release from his self-imposed immaturity.”

“Act only according to that maxim by which you can at the same time will that it should become a universal law.”

“Two things fill the mind with ever new and increasing admiration and awe: the starry heavens above me and the moral law within me.”

“Act so that you treat humanity, whether in your own person or in that of another, always as an end and never merely as a means.”

“Nothing in the world, nor even beyond it, can possibly be conceived as good without limitation, except a good will.”

“Thinking is speaking with oneself.”

“The beautiful is the symbol of the morally good.”

“Man can only become man through education.”

“Laziness and cowardice are the reasons why so many people gladly remain immature for life.”
