We can learn to suppress our feelings for other reasons.

We have so far to go to realize our human potential for compassion, altruism, and love.

I've got different ideas of complete happiness. But one is being by myself out in a forest, completely happy. Another is walking with a dog in some nice place. And three is sitting around preferably a fire, but not necessarily, and drinking red wine with friends and telling stories.

I became intensely aware of the being-ness of trees. The feel of rough sun-warmed bark of an ancient forest giant, or the cool, smooth skin of a young and eager sapling, gave me a strange, intuitive sense of the sap as it was sucked up by unseen roots and drawn up to the very tips of the branches, high overhead.

A chimp would never plan to pull another's nails out.

For those who have experienced the joy of being alone with nature there is really little need for me to say much more; for those who have not, no words of mine can ever describe the powerful, almost mystical knowledge of beauty and eternity that come, suddenly, and all unexpected.

I believe the only hope for mankind lies in the hands of our young people.
