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.

I often wonder how much sound and nourishing food is fed to the animals in the zoological gardens of America every week, and try to figure out what the public gets in return for the cost thereof. The annual bill must surely run into millions; one is constantly hearing how much beef a lion downs at a meal, and how many tons of hay an elephant dispatches in a month. And to what end? To the end, principally, that a horde of superintendents and keepers may be kept in easy jobs. To the end, secondarily, that the least intelligent minority of the population may have an idiotic show to gape at on Sunday afternoons, and that the young of the species may be instructed in the methods of amour prevailing among chimpanzees and become privy to the technic employed by jaguars, hyenas and polar bears in ridding themselves of lice.

So far as I can make out, after laborious visits to all the chief zoos of the nation, no other imaginable purpose is served by their existence. One hears constantly, true enough (mainly from the gentlemen they support) that they are educational. But how? Just what sort of instruction do they radiate, and what is its value? I have never been able to find out. The sober truth is that they are no more educational than so many firemen's parades or displays of sky-rockets, and that all they actually offer to the public in return for the taxes wasted upon them is a form of idle and witless amusement, compared to which a visit to a penitentiary, or even to Congress or a state legislature in session, is informing, stimulating and ennobling.

Education your grandmother! Show me a schoolboy who has ever learned anything valuable or important by watching a mangy old lion snoring away in its cage or a family of monkeys fighting for peanuts. To get any useful instruction out of such a spectacle is palpably impossible; not even a college professor is improved by it. The most it can imaginably impart is that the stripes of a certain sort of tiger run one way and the stripes of another sort some other way, that hyenas and polecats smell worse than Greek 'bus boys, that the Latin name of the raccoon (who was unheard of by the Romans) is Procyon lotor. For the dissemination of such banal knowledge, absurdly emitted and defectively taken in, the taxpayers of the United States are mulcted in hundreds of thousands of dollars a year. As well make them pay for teaching policemen the theory of least squares, or for instructing roosters in the laying of eggs.

But zoos, it is argued, are of scientific value. They enable learned men to study this or that. Again the facts blast the theory. No scientific discovery of any value whatsoever, even to the animals themselves, has ever come out of a zoo. The zoo scientist is the old woman of zoology, and his alleged wisdom is usually exhibited, not in the groves of actual learning, but in the yellow journals. He is to biology what the late Camille Flammarion was to astronomy, which is to say, its court jester and reductio ad absurdum. When he leaps into public notice with some new pearl of knowledge, it commonly turns out to be no more than the news that Marie Bashkirtseff, the Russian lady walrus, has had her teeth plugged with zinc and is expecting twins. Or that Pishposh, the man-eating alligator, is down with locomotor ataxia. Or that Damon, the grizzly, has just finished his brother Pythias in the tenth round, chewing off his tail, nose and remaining ear.

Science, of course, has its uses for the lower animals. A diligent study of their livers and lights helps to an understanding of the anatomy and physiology, and particularly of the pathology, of man. They are necessary aids in devising and manufacturing many remedial agents, and in testing the virtues of those already devised; out of the mute agonies of a rabbit or a calf may come relief for a baby with diphtheria, or means for an archdeacon to escape the consequences of his youthful follies. Moreover, something valuable is to be got out of a mere study of their habits, instincts and ways of mind—knowledge that, by analogy, may illuminate the parallel doings of the genus homo, and so enable us to comprehend the primitive mental processes of Congressmen, morons and the rev. clergy.

But it must be obvious that none of these studies can be made in a zoo. The zoo animals, to begin with, provide no material for the biologist; he can find out no more about their insides than what he discerns from a safe distance and through the bars. He is not allowed to try his germs and specifics upon them; he is not allowed to vivisect them. If he would find out what goes on in the animal body under this condition or that, he must turn from the inhabitants of the zoo to the customary guinea pigs and street dogs, and buy or steal them for himself. Nor does he get any chance for profitable inquiry when zoo animals die (usually of lack of exercise or ignorant doctoring), for their carcasses are not handed to him for autopsy, but at once stuffed with gypsum and excelsior and placed in some museum.

Least of all do zoos produce any new knowledge about animal behavior. Such knowledge must be got, not from animals penned up and tortured, but from animals in a state of nature. A college professor studying the habits of the giraffe, for example, and confining his observations to specimens in zoos, would inevitably come to the conclusion that the giraffe is a sedentary and melancholy beast, standing immovable for hours at a time and employing an Italian to feed him hay and cabbages. As well proceed to a study of the psychology of a juris-consult by first immersing him in Sing Sing, or of a juggler by first cutting off his hands. Knowledge so gained is inaccurate and imbecile knowledge. Not even a college professor, if sober, would give it any faith and credit.

There remains, then, the only true utility of a zoo: it is a childish and pointless show for the unintelligent, in brief, for children, nursemaids, visiting yokels and the generality of the defective. Should the taxpayers be forced to sweat millions for such a purpose? I think not. The sort of man who likes to spend his time watching a cage of monkeys chase one another, or a lion gnaw its tail, or a lizard catch flies, is precisely the sort of man whose mental weakness should be combatted at the public expense, and not fostered. He is a public liability and a public menace, and society should seek to improve him. Instead of that, we spend a lot of money to feed his degrading appetite and further paralyze his mind. It is precisely as if the community provided free champagne for dipsomaniacs, or hired lecturers to convert the army to the doctrines of the Bolsheviki.

Of the abominable cruelties practised in zoos it is unnecessary to make mention. Even assuming that all the keepers are men of delicate natures and ardent zoophiles (which is about as safe as assuming that the keepers of a prison are all sentimentalists, and weep for the sorrows of their charges), it must be plain that the work they do involves an endless war upon the native instincts of the animals, and that they must thus inflict the most abominable tortures every day. What could be a sadder sight than a tiger in a cage, save it be a forest monkey climbing dispairingly up a barked stump, or an eagle chained to its roost? How can man be benefitted and made better by robbing the seal of its arctic ice, the hippopotamus of its soft wallow, the buffalo of its open range, the lion of its kingship, the birds of their air?

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.

If I had the time, and there were no sweeter follies offering, I should like to write an essay on the books that have quite failed of achieving their original purposes, and are yet of respectable use and potency for other purposes. For example, the Book of Revelation. The obvious aim of the learned author of this work was to bring the early Christians into accord by telling them authoritatively what to expect and hope for; its actual effect during eighteen hundred years has been to split them into a multitude of camps, and so set them to denouncing, damning, jailing and murdering one another. Again, consider the autobiography of Benvenuto Cellini. Ben wrote it to prove that he was an honest man, a mirror of all the virtues, an injured innocent; the world, reading it, hails him respectfully as the noblest, the boldest, the gaudiest liar that ever lived. Again, turn to "Gulliver's Travels." The thing was planned by its rev. author as a devastating satire, a terrible piece of cynicism; it survives as a story-book for sucklings. Yet again, there is "Hamlet." Shakespeare wrote it frankly to make money for a theatrical manager; it has lost money for theatrical managers ever since. Yet again, there is Caesar's "De Bello Gallico." Julius composed it to thrill and arouse the Romans; its sole use today is to stupefy and sicken schoolboys. Finally, there is the celebrated book of General F. von Bernhardi. He wrote it to inflame Germany; its effect was to inflame England....

The list might be lengthened almost ad infinitum. When a man writes a book he fires a machine gun into a wood. The game he brings down often astonishes him, and sometimes horrifies him. Consider the case of Ibsen.... After my book on Nietzsche I was actually invited to lecture at Princeton.
