Intelligence is almost useless to the person whose only quality it is.

Prayer, the basic exercise of the spirit, must be actively practiced in our private lives. The neglected soul of the human being must be made strong enough to assert itself once more. For if the power of prayer is again released and used in the lives of common men and women; if the spirit declares its aims clearly and boldly, there is yet hope that our prayers for a better world will be answered.

Comforts and syphilis are the greatest enemies of mankind.

Prayer, like radium, is a luminous and self-generating form of energy.

Prayer is a force as real as terrestrial gravity. As a physician, I have seen men lifted out of sickness by the power of prayer. It is the only power in the world that overcomes the laws of nature.

It seems that the increased number of scientific workers, their being split up into groups whose studies are limited to a small subject, and over-specialization have brought about a shrinking of intelligence. There is no doubt that the quality of any human group decreases when the number of the individuals composing this group increases beyond certain limits... The best way to increase the intelligence of scientists would be to decrease their number.

The atmosphere of libraries, lecture rooms and laboratories is dangerous to those who shut themselves up in them too long. It separates us from reality like a fog.
