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

“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.”

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

“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.”

“[Standing armies] constantly threaten other nations with war by giving the appearance that they are prepared for it, which goads nations into competing with one another in the number of men under arms, and this practice knows no bounds. And since the costs related to maintaining peace will in this way finally become greater than those of a short war, standing armies are the cause of wars of aggression that are intended to end burdensome expenditures. Moreover, paying men to kill or be killed appears to use them as mere machines and tools in the hands of another (the nation), which is inconsistent with the rights of humanity.”

“From the crooked timber of humanity, a straight board cannot be hewn.”
