Shut your eyes and you will know what I mean by thought entombed in darkness. Light comes through the senses, and not only through the sense of sight. When you see without feeling, you are still partly blind; you lack the inner light that brings awareness. Awareness requires the interplay of every faculty, the use of your entire being as an eye.

I believe that for permanent survival, man must balance science with other qualities of life, qualities of body and spirit as well as those of mind - qualities he cannot develop when he lets mechanics and luxury insulate him too greatly from the earth to which he was born.

I don't believe in taking foolish chances, but nothing can be accomplished if we don't take any chances at all.

It is not the willingness to kill on the part of our soldiers which most concerns me. That is an inherent part of war. It is our lack of respect for even the admirable characteristics of our enemy; for courage, for suffering, for death, for his willingness to die for his beliefs, for his companies and squadrons which go forth, one after another, to annihilation against our superior training and equipment.
