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.
I will never apologize for saying that the future of humanity and the future of the world is going to be defined by what we have in common as opposed to those things that separate us and ultimately lead us into conflict.

Our chief usefulness to humanity rests on our combining power with high purpose. Power undirected by high purpose spells calamity, and high purpose by itself is utterly useless if the power to put it into effect is lacking.
