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.

Tact is not a small thing; in the battle of life it is more powerful than a bludgeon.

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

We must rejoice when love is great, and pardon its excess, for love is the staff of life, and life without love is life in vain.

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 future seems a little gloomy! Go to bed early, sleep well, eat moderately at breakfast; the future looks brighter. The world's outlook may not have changed, but our capacity for dealing with it has. Happiness, or unhappiness, depends to some extent on external conditions, but also, and in most cases chiefly, on our own physical and mental powers. Some people would be discontented in Paradise, others ... are cheerful in a graveyard.

So this is happiness, that journeyman.
