I am no sentimentalist, God knows. I am in favor of vivisection unrestrained, so long as the vivisectionist knows what he is about. I advocate clubbing a dog that barks unnecessarily, which all dogs do. I enjoy hangings, particularly of converts to the evangelical faiths. The crunch of a cockroach is music to my ears. But when the day comes to turn the prisoners of the zoo out of their cages, if it is only to lead them to the swifter, kinder knife of the _schochet_, I shall be present and rejoicing, and if any one present thinks to suggest that it would be a good plan to celebrate the day by shooting the whole zoo faculty, I shall have a revolver in my pocket and a sound eye in my head. XXXVII ON HEARING MOZART The only permanent values in the world are truth and beauty, and of these it is probable that truth is lasting only in so far as it is a function and manifestation of beauty--a projection of feeling in terms of idea. The world is a charnel house of dead religions. Where are all the faiths of the middle ages, so complex and yet so precise? But all that was essential in the beauty of the middle ages still lives.... This is the heritage of man, but not of men. The great majority of men are not even aware of it. Their participation in the progress of the world, and even in the history of the world, is infinitely remote and trivial. They live and die, at bottom, as animals live and die. The human race, as a race, is scarcely cognizant of their existence; they haven't even definite number, but stand grouped together as _x_, the quantity unknown ... and not worth knowing. XXXVIII THE ROAD TO DOUBT The first effect of what used to be called natural philosophy is to fill its devotee with wonder at the marvels of God. This explains why the pursuit of science, so long as it remains superficial, is not incompatible with the most naif sort of religious faith. But the moment the student of the sciences passes this stage of childlike amazement and begins to investigate the inner workings of natural phenomena, he begins to see how ineptly many of them are managed, and so he tends to pass from awe of the Creator to criticism of the Creator, and once he has crossed that bridge he has ceased to be a believer. One finds plenty of neighborhood physicians, amateur botanists, high-school physics teachers and other such quasi-scientists in the pews on Sunday, but one never sees a Huxley there, or a Darwin, or an Ehrlich.
