Science is knowledge arranged and classified according to truth, facts, and the general laws of nature.

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.

If we had paid no more attention to our plants than we have to our children, we would now be living in a jungle of weed.

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.

And to think of this great country in danger of being dominated by people ignorant enough to take a few ancient Babylonian legends as the canons of modern culture. Our scientific men are paying for their failure to speak out earlier. There is no use now talking evolution to these people. Their ears are stuffed with Genesis.

All my work has come about through a change in my earlier opinion of religion.

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