"Ingratitude is the essence of vileness...." - Quote by Immanuel Kant

“Everything in nature acts in conformity with law.”

“Maximum individuality within maximum community”

“I have no knowledge of myself as I am, but merely as I appear to myself.”

“Gentlemen, let us suppose that man is not stupid. (Indeed one cannot refuse to suppose that, if only from the one consideration, that, if man is stupid, then who is wise?) But if he is not stupid, he is monstrously ungrateful! Phenomenally ungrateful. In fact, I believe that the best definition of man is the ungrateful biped.”

“You, and your lady, Take from my heart all thankfulness!”

“I hate ingratitude more in a man than lying, vainness, babbling, drunkenness, or any taint of vice whose strong corruption inhabits our frail blood".”

“It is far pleasanter to injure and afterwards beg forgiveness than to be injured and grant forgiveness. He who does the former gives evidence of power and afterwards of kindness of character.”

“Character, in great and little things, means carrying through what you feel able to do.”

“Self-command is the main elegance.”
