It has become appallingly obvious that our technology has exceeded our humanity.

Nothing will benefit human health and increase chances for survival of life on Earth as much as the evolution to a vegetarian diet.

Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar", every "supreme leader", every saint and sinner in the history of our species lived there — on a mote of dust suspended in a sunbeam.

You must not lose faith in humanity. Humanity is an ocean; if a few drops of the ocean are dirty, the ocean does not become dirty.

We're terrible animals. I think that the Earth's immune system is trying to get rid of us, as well it should. On humans, September 2005.

I was taught that the human brain was the crowning glory of evolution so far, but I think it’s a very poor scheme for survival. 27 December 1987

I am absolutely convinced that no wealth in the world can help humanity forward, even in the hands of the most devoted worker in this cause. The example of great and pure characters is the only thing that can produce fine ideas and noble deeds. Money only appeals to selfishness and always tempts its owners irresistibly to abuse it. Can anyone imagine Moses, Jesus, or Gandhi armed with the money-bags of Carnegie?

Every one of us is precious in the cosmic perspective. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.

The great moral teachers of humanity were, in a way, artistic geniuses in the art of living.

Whether humanity will consciously follow the law of love, I do not know. But that need not disturb me. The law will work just as the law of gravitation works, whether we accept it or not. The person who discovered the law of love was a far greater scientist than any of our modern scientists. Only our explorations have not gone far enough and so it is not possible for everyone to see all its workings.
