Now the students of heredity, especially, understand all of their subject except their subject. They were, I suppose, bred and born in that brierpatch, and have really explored it without coming to the end of it. That is, they have studied everything but the question of what they are studying. Now I do not propose to rely merely on myself to tell them what they are studying. I propose, as will be seen in a moment, to call the testimony of a great man who has himself studied it. But to begin with, the domain of heredity (for those who see its frontiers) is a sort of triangle, enclosed on its three sides by three facts. The first is that heredity undoubtedly exists, or there would be no such thing as a family likeness, and every marriage might suddenly produce a small negro. The second is that even simple heredity can never be simple; its complexity must be literally unfathomable, for in that field fight unthinkable millions. But yet again it never is simple heredity: for the instant anyone is, he experiences. The third is that these innumerable ancient influences, these instant inundations of experiences, come together according to a combination that is unlike anything else on this earth. It is a combination that does combine. It cannot be sorted out again, even on the Day of Judgment. Two totally different people have become in the sense most sacred, frightful, and unanswerable, one flesh. If a goldenhaired Scandinavian girl has married a very swarthy Jew, the Scandinavian side of the family may say till they are blue in the face that the baby has his mother's nose or his mother's eyes. They can never be certain the blackhaired Bedouin is not present in every feature, in every inch. In the person of the baby he may have gently pulled his wife's nose. In the person of the baby he may have partly blacked his wife's eyes.
Those are the three first facts of heredity. That it exists; that it is subtle and made of a million elements; that it is simple, and cannot be unmade into those elements. To summarise: you know there is wine in the soup. You do not know how many wines there are in the soup, because you do not know how many wines there are in the world. And you never will know, because all chemists, all cooks, and all commonsense people tell you that the soup is of such a sort that it can never be chemically analysed. That is a perfectly fair parallel to the hereditary element in the human soul. There are many ways in which one can feel that there is wine in the soup, as in suddenly tasting a wine specially favoured; that corresponds to seeing suddenly flash on a young face the image of some ancestor you have known. But even then the taster cannot be certain he is not tasting one familiar wine among many unfamiliar onesor seeing one known ancestor among a million unknown ancestors. Another way is to get drunk on the soup, which corresponds to the case of those who say they are driven to sin and death by hereditary doom. But even then the drunkard cannot be certain it was the soup, any more than the traditional drunkard who is certain it was the salmon.
Those are the facts about heredity which anyone can see. The upshot of them is not only that a miss is as good as a mile, but a miss is as good as a win. If the child has his parents' nose (or noses) that may be heredity. But if he has not, that may be heredity too. And as we need not take heredity lightly because two generations differso we need not take heredity a scrap more seriously because two generations are similar. The thing is there, in what cases we know not, in what proportion we know not, and we cannot know.
Now it is just here that the decent difference of function between Dr. Saleeby's trade and mine comes in. It is his business to study human health and sickness as a whole, in a spirit of more or less enlightened guesswork; and it is perfectly natural that he should allow for heredity here, there, and everywhere, as a man climbing a mountain or sailing a boat will allow for weather without even explaining it to himself. An utterly different attitude is incumbent on any conscientious man writing about what laws should be enforced or about how commonwealths should be governed. And when we consider how plain a fact is murder, and yet how hesitant and even hazy we all grow about the guilt of a murderer, when we consider how simple an act is stealing, and yet how hard it is to convict and punish those rich commercial pirates who steal the most, when we consider how cruel and clumsy the law can be even about things as old and plain as the Ten CommandmentsI simply cannot conceive any responsible person proposing to legislate on our broken knowledge and bottomless ignorance of heredity.
But though I have to consider this dull matter in its due logical order, it appears to me that this part of the matter has been settled, and settled in a most masterly way, by somebody who has infinitely more right to speak on it than I have. Our press seems to have a perfect genius for fitting people with caps that don't fit; and affixing the wrong terms of eulogy and even the wrong terms of abuse. And just as people will talk of Bernard Shaw as a naughty winking Pierrot, when he is the last great Puritan and really believes in respectability; just as (si parva licet etc.) they will talk of my own paradoxes, when I pass my life in preaching that the truisms are true; so an enormous number of newspaper readers seem to have it fixed firmly in their heads that Mr. H.G. Wells is a harsh and horrible Eugenist in great goblin spectacles, who wants to put us all into metallic microscopes and dissect us with metallic tools. As a matter of fact, of course, Mr. Wells, so far from being too definite, is generally not definite enough. He is an absolute wizard in the appreciation of atmospheres and the opening of vistas; but his answers are more agnostic than his questions. His books will do everything except shut. And so far from being the sort of man who would stop a man from propagating, he cannot even stop a full stop. He is not Eugenic enough to prevent the black dot at the end of a sentence from breeding a line of little dots.
But this is not the clearcut blunder of which I spoke. The real blunder is this. Mr. Wells deserves a tiara of crowns and a garland of medals for all kinds of reasons. But if I were restricted, on grounds of public economy, to giving Mr. Wells only one medal ob cives servatos, I would give him a medal as the Eugenist who destroyed Eugenics. For everyone spoke of him, rightly or wrongly, as a Eugenist; and he certainly had, as I have not, the training and type of culture required to consider the matter merely in a biological and not in a generally moral sense. The result was that in that fine book, "Mankind in the Making," where he inevitably came to grips with the problem, he threw down to the Eugenists an intellectual challenge which seems to me unanswerable, but which, at any rate, is unanswered. I do not mean that no remote Eugenist wrote upon the subject; for it is impossible to read all writings, especially Eugenist writings. I do mean that the leading Eugenists write as if this challenge had never been offered. The gauntlet lies unlifted on the ground.
Having given honour for the idea where it is due, I may be permitted to summarise it myself for the sake of brevity. Mr. Wells' point was this. That we cannot be certain about the inheritance of health, because health is not a quality. It is not a thing like darkness in the hair or length in the limbs. It is a relation, a balance. You have a tall, strong man; but his very strength depends on his not being too tall for his strength. You catch a healthy, fullblooded fellow; but his very health depends on his being not too full of blood. A heart that is strong for a dwarf will be weak for a giant; a nervous system that would kill a man with a trace of a certain illness will sustain him to ninety if he has no trace of that illness. Nay, the same nervous system might kill him if he had an excess of some other comparatively healthy thing. Seeing, therefore, that there are apparently healthy people of all types, it is obvious that if you mate two of them, you may even then produce a discord out of two inconsistent harmonies. It is obvious that you can no more be certain of a good offspring than you can be certain of a good tune if you play two fine airs at once on the same piano. You can be even less certain of it in the more delicate case of beauty, of which the Eugenists talk a great deal. Marry two handsome people whose noses tend to the aquiline, and their baby (for all you know) may be a goblin with a nose like an enormous parrot's. Indeed, I actually know a case of this kind. The Eugenist has to settle, not the result of fixing one steady thing to a second steady thing; but what will happen when one toppling and dizzy equilibrium crashes into another.
This is the interesting conclusion. It is on this degree of knowledge that we are asked to abandon the universal morality of mankind. When we have stopped the lover from marrying the unfortunate woman he loves, when we have found him another uproariously healthy female whom he does not love in the least, even then we have no logical evidence that the result may not be as horrid and dangerous as if he had behaved like a man of honour.
Chapter VII
The Established Church of Doubt
Let us now finally consider what the honest Eugenists do mean, since it has become increasingly evident that they cannot mean what they say. Unfortunately, the obstacles to any explanation of this are such as to insist on a circuitous approach. The tendency of all that is printed and much that is spoken today is to be, in the only true sense, behind the times. It is because it is always in a hurry that it is always too late. Give an ordinary man a day to write an article, and he will remember the things he has really heard latest; and may even, in the last glory of the sunset, begin to think of what he thinks himself. Give him an hour to write it, and he will think of the nearest textbook on the topic, and make the best mosaic he may out of classical quotations and old authorities. Give him ten minutes to write it and he will run screaming for refuge to the old nursery where he learnt his stalest proverbs, or the old school where he learnt his stalest politics. The quicker goes the journalist the slower go his thoughts. The result is the newspaper of our time, which every day can be delivered earlier and earlier, and which, every day, is less worth delivering at all. The poor panting critic falls farther and farther behind the motorcar of modern fact. Fifty years ago he was barely fifteen years behind the times. Fifteen years ago he was not more than fifty years behind the times. Just now he is rather more than a hundred years behind the times: and the proof of it is that the things he says, though manifest nonsense about our society today, really were true about our society some hundred and thirty years ago. The best instance of his belated state is his perpetual assertion that the supernatural is less and less believed. It is a perfectly true and realistic accountof the eighteenth century. It is the worst possible account of this age of psychics and spirithealers and fakirs and fashionable fortunetellers. In fact, I generally reply in eighteenth century language to this eighteenth century illusion. If somebody says to me, "The creeds are crumbling," I reply, "And the King of Prussia, who is himself a Freethinker, is certainly capturing Silesia from the Catholic Empress." If somebody says, "Miracles must be reconsidered in the light of rational experience," I answer affably, "But I hope that our enlightened leader, Hébert, will not insist on guillotining that poor French queen." If somebody says, "We must watch for the rise of some new religion which can commend itself to reason," I reply, "But how much more necessary is it to watch for the rise of some military adventurer who may destroy the Republic: and, to my mind, that young Major Bonaparte has rather a restless air." It is only in such language from the Age of Reason that we can answer such things. The age we live in is something more than an age of superstitionit is an age of innumerable superstitions. But it is only with one example of this that I am concerned here.
