More trouble is caused in this world by indiscreet answers than by indiscreet questions.

All our efforts to attain immortality-by statesmanship, by conquest, by science or the arts-are equally vain in the long run, because the long run is longer than any of us can imagine.

The greatest educational dogma is also its greatest fallacy: the belief that what must be learned can necessarily be taught.

It wants to be, and proclaims itself to be, 'the greatest', but greatness is not required of a country; only goodness is.

Most people are mirrors, reflecting the moods and emotions of the times; few are windows, bringing light to bear on the dark corners where troubles fester. The whole purpose of education is to turn mirrors into windows.
