As a scientist, I can not help feeling that all religions are on a tottering foundation. None is perfect or inspired.The idea that a good God would send people to a burning hell is utterly damnable to me. I don't want to have anything to do with such a God.

The secret of improved plant breeding, apart from scientific knowledge, is love.

Less than fifteen per cent of the people do any original thinking on any subject. The greatest torture in the world for most people is to think.

I see humanity now as one vast plant, needing for its highest fulfillment only love, the natural blessings of the great outdoors, and intelligent crossing and selection.

Thinking is the greatest torture in the world for most people.

Nature is not personal. She is the compound of all these processes which move through the universe to effect the results we know as Life and of all the ordinances which govern that universe and that make Life continuous. She is no more the Hebrew's Jehovah than she is the Physicist's Force; she is as much Providence as she is Electricity; she is not the Great Pattern any more than she is the Blind Chance.

I have seen myself lose intolerance, narrowness, bigotry, complacence, pride and a whole bushel-basket of other intellectual vices through my contact with Nature and with men. And when you take weeds out of a garden it gives you room to grow flowers. So, every time I lost a little self-satisfaction, or arrogance, I could plant some broadness or love of my own in its place, and after a while the garden of my mind began to bloom and be fragrant and I found myself better equipped for my work and more useful to others as a consequence.
