No technical knowledge can outweigh knowledge of the humanities.

Imagination without deep and full knowledge is a snare.

The stomach is the only part of man which can be fully satisfied. The yearning of man's brain for new knowledge and experience and for more pleasant and comfortable surroundings never can be completely met. It is an appetite which cannot be appeased.

Knowledge cannot be taken away from anyone except by obsolescence.

I only hope that when I am free, as they are free to go in quest, of the knowledge beyond the bounds of life, it may not seem better to me to rest.

Power comes not from knowledge kept but from knowledge shared.
