Brief is this existence, as a visit in a strange house. The path to be pursued is poorly lit by a flickering consciousness.

A country cannot simultaneously prepare and prevent war. I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones. The distinctions separating the social classes are false; in the last analysis they rest on force.

For an idea which, at first, does not seem absurd, there is no hope.

It is just as important to make knowledge live and keep it alive as to solve specific problems.

All means prove but blunt instruments, if they have not behind them a living spirit.

Knowledge is dead; the school, however, serves the living.

It is abhorrent to me when a fine intelligence is paired with an unsavory character.
