“Act in such a way that you treat humanity, whether in your own person or in the person of any other, never merely as a means to an end, but always at the same time as an end.”

“Human beings are never to be treated as a means but always as ends.”

“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.”

“Any humane and reasonable person must conclude that if the ends, however desireable, are uncertain and the means are horrible and certain, these means must not be employed.”

“I myself must also say I believe it is true that in the end humanitarianism will triumph; only I fear that at the same time the world will be one big hospital and each person will be the other person's humane keeper.”

“Treat people as an end, and never as a means to an end”
