Religion grows with the intelligence of man, but all religions of the past and probably all of the future will sooner or later become petrified forms instead of living helps to mankind. Until that time comes, however, if religion of any name or nature makes man more happy, comfortable, and able to live peaceably with his brothers, it is good.

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

I am an infidel. I know what an infidel is, and that's what I am.

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.

Science is the only savior.
