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.
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.
Wit is something more than a gymnastic trick of the intellect; true wit implies a beam of thought into the essence of a question, a flash that lights up a situation. Wit suggests the delicate but delightful play of a rapier in the hands of a master.
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.
