There is no worse screen to block out the spirit than confidence in our own intelligence

Of all treasons against humanity, there is no one worse than his who employs great intellectual force to keep down the intellect of his less favored brothers

“Literature - the expression of a nation's mind in writing

It is mind which does the work of the world, so that the more there is of mind, the more work will be accomplished

Logic is the technique by which we add conviction to truth

For where the instrument of intelligence is added to brute power and evil will, mankind is powerless in its own defense
