Life leaps like a geyser for those willing to drill through the rock of inertia.

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.

Only in prayer do we achieve that complete and harmonious assembly of body, mind, and spirit which gives the frail human reed its unshakable strength.

Men grow when inspired by a high purpose, when contemplating vast horizons. The sacrifice of oneself is not very difficult for one burning with the passion for a great adventure.

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.
