Pessimism is carefully cultivated in some intellectual circles, as if it were a precious plant that the human race could not afford to lose.

Children should not be coddled in their intellectual training any more than in their physical; and though the studies should be made interesting the interest should arise out of the studies themselves. We have bred a generation that cannot digest anything intellectual but tablets of peptonized food. One sees that in the popular papers with their brevity, still increasing in brevity as far as brevity can increase, and in the capacity for thought of our rulers.

Pessimism is a product of our civilization. It is not natural to the savage; he feels pain, or discomfort, and suffers from these palpable conditions, but when he recovers from wounds he forgets the torments, and when he is well fed he is joyous in the light of day.

The accumulation of facts, even if interesting in themselves, should not constitute the main part of education; these facts, whether they be of classical learning or knick-knacks of history, will be of little use unless the mind has been trained to see them in proper perspective.

Some people would be discontented in Paradise, others ... are cheerful in a graveyard.

Yet as I cast my eye over the whole course of science I behold instances of false science, even more pretentious and popular than that of Einstein gradually fading into ineptitude under the searchlight; and I have no doubt that there will arise a new generation who will look with a wonder and amazement, deeper than now accompany Einstein, at our galaxy of thinkers, men of science, popular critics, authoritative professors and witty dramatists, who have been satisfied to waive their common sense in view of Einstein's absurdities.

So this is happiness, that journeyman.
