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.

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

We must return to nature and nature's god.

If you violate Nature's laws you are your own prosecuting attorney, judge, jury, and hangman.

A theory of personal resurrection or reincarnation of the individual is untenable when we but pause to consider the magnitude of the idea. On the contrary, I must believe that rather than the survival of all, we must look for survival only in the spirit of the good we have done in passing through.Once obsolete, an automobile is thrown to the scrap heap. Once here and gone, the human life has likewise served its purpose. If it has been a good life, it has been sufficient. There is no need for another.

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.
