Love measures our stature: the more we love, the bigger we are.

I'm delighted that the future is unsure. That's the way it should be.

The world is too dangerous for anything but truth and too small for anything but love.

Without love, violence will change the world; it will change it into a more violent one.

The cause of violence is not ignorance. It is self-interest. Only reverance can restrain violence - reverance for human life and the environment.

Truth is always in danger of being sacrificed on the altars of good taste and social stability.

Patriotism at the expense of another nation is as wicked as racism at the expense of another race. . . Let us resolve to be patriots always, nationalists never. Let us love our country, but pledge allegiance to the earth and to the flora and fauna and human life that it supports - one planet indivisible, with clean air,... soil and water; with liberty, justice and peace for all.
