Thought must be divided against itself before it can come to any knowledge of itself.

This really revolutionary revolution is to be achieved, not in the external world, but in the souls and flesh of human beings.

To be well informed, one must read quickly a great number of merely instructive books. To be cultivated, one must read slowly and with a lingering appreciation the comparatively few books that have been written by men who lived, thought, and felt with style.

It is delightful to read on the spot the impressions and opinions of tourists who visited a hundred years ago, in the vehicles and with the aesthetic prejudices of the period, the places which you are visiting now. The voyage ceases to be a mere tour through space; you travel through time and thought as well.

Ultimate Reality is not clearly and immediately apprehended except by those who have made themselves loving, pure in heart and poor in spirit.

Today we are faced, I think, with the approach of what may be called the ultimate revolution, the final revolution, where man can act directly on the mind-body of his fellows.
