I don’t remember when first I heard Them calling, with their silvery voices, The little Angels of the trees and flowers. They offered to unlock my mind And take my soul away, to clean. And oh! I welcomed them, and lay Stretched out upon the fragrant Grass, light as an empty husk. Then they, with rueful smiles, did oil The rusty hinges of my mind, and swept Away the cobwebs, and hung my soul Upon a topmost bough, to air, Close to the purifying sun. And I was lucky For as it fluttered there, a robin chat’s sweet Song rose through the trees till every fiber Of my soul was bathed in harmony. When all was clean and new they fetched My soul and slipped it back and, smiling, Danced away. And I — well, for a day or two — I looked upon the world with all the Innocence and wonder of a newborn babe. And now, if I am sad, or filled With sudden rage, I find some quiet place With grass and leaves and earth, and sit there Silently, and hope that they will come And call me, with their silvery voices, And make me clean again, those Little Angels of the trees and flowers.

I don't have any idea of who or what God is. But I do believe in some great spiritual power. I feel it particularly when I'm out in nature. It's just something that's bigger and stronger than what I am or what anybody is. I feel it. And it's enough for me.

At that moment there was no need of any scientific knowledge to understand his communication of reassurance. The soft pressure of his fingers spoke to me not through my intellect but through a more primitive emotional channel: the barrier of untold centuries which has grown up during the separate evolution of man and chimpanzee was, for those few seconds, broken down.

It was a reward far beyond my greatest hopes.

There are really only two ways, it seems to me, in which we can think about our existence here on earth. We either agree with Macbeth that life is nothing more than a “tale told by an idiot,” a purposeless emergence of life-forms including the clever, greedy, selfish, and unfortunately destructive species that we call Homo sapiens — the “evolutionary goof.” Or we believe that, as Pierre Teilhard de Chardin put it, “There is something afoot in the universe, something that looks like gestation and birth.” In other words, a plan, a purpose to it all.

I like to envision the whole world as a jigsaw puzzle... If you look at the whole picture, it is overwhelming and terrifying, but if you work on your little part of the jigsaw and know that people all over the world are working on their little bits, that's what will give you hope.

"The more we learn of the true nature of non-human animals, especially those with complex brains and corresponding complex social behavior, the more ethical concerns are raised regarding their use in the service of man — whether this be in entertainment, as "pets," for food, in research laboratories, or any of the other uses to which we subject them."
