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

Flowers always make people better, happier, and more helpful; they are sunshine, food and medicine for the soul.

As a scientist, I cannot help feeling that all religions are on a tottering foundation . . . I am an infidel today. I do not believe what had been served to me to believe. I am a doubter, a questioner, a skeptic. When it can be proved to me that there is immortality, that there is resurrection beyond the gates of death, then will I believe. Until then, no.

What is the use of assuring Fundamentalists that science is compatible with religion. They retort at once, Certainly not with our religion.

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.

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.

In the span of my own lifetime I observed such wondrous progress in plant evolution that I look forward optimistically to a healthy, happy world as soon as its children are taught the principles of simple and rational living.
