Amid breathless silence, Dr. Strahl rose to speak, after he had given up the chair to his colleague Ney, of the Freeland government.

Our friend of the Right (he began) ended his appeal to us with the question whether we in Freeland knew of any means which would compel the herrings to confine the increase in their numbers within such bounds as would best conduce to the prosperous continuance of their species. My answer is brief and to the point: Yes, we know of such a means. [Sensation.] You are astonished? You need not be, dear friends, for you know of it as well as we do; and what leads you to think you do not know of it is merely that peculiar mental shortsightedness which prevents men from perceiving the application of well-known facts to any subject upon which the prejudices they have drunk in with their mother's milk prevent them making a right use of their senses and their judgment. So I assert that you all know of the means in question as well as we do. But I do not say, as you seem to assume, that either you or we were in a position to teach this prudence to the herrings--a task, in fact, which would be scarcely practicable. I assert, rather, that our common knowledge of the means in question is derived not from our gift of invention, but from our gift of observation--in other words, that the herrings have always acted in the way in which, according to the opinion of the propounder of the question, they need to be taught how to act by our wisdom; and that, therefore, in order to attain to a knowledge of the mode of action in question, we need merely first, open our eyes and see what goes on in nature, and secondly, make some use of our understanding in order that we may find out the how of this natural procedure.

Let us, then, first open our eyes--that is, let us remove the bandages with which inherited economic prejudices have blinded us. To make this the easier, my friends, I ask you to fix your mind upon any living thing--the herring, for example--without thinking of any possible reference which it may have to the question of population in human society. Do not seek among the herrings for any explanation of human misery, but regard them simply as one of the many kinds of boarders at the table of nature. It will then be impossible for you not to perceive that, though this species of animal is represented by very many individuals, yet those individuals are not too numerous to find places at nature's table. Nay, I assert that--always supposing you keep merely the herring in mind, and are not at the same time looking at human misery in the background--you would think it absurd to suppose for a moment that the herrings, if they were more numerous than they are, would not find food enough in the ocean--that there were just as many of them as could be fully fed at the table of nature. Or let us take another species of animal, the relations between which and its food-supply we are not obliged to arrive at by reflection, but, if necessary, could easily discover by actual observation--namely, the elephant. Malthus calculated how long it would take for a pair of elephants to fill the world with their descendants, and concluded that it would be lack of food which would ultimately check their indefinite increase. Does not the most superficial glance show you that nowhere on the earth are there nearly so many elephants as would find nourishment in abundance? Would you not think anyone a dotard who would try to convince you of the contrary? Thus you all know--and I wish first of all to make sure of this--that every kind of animal, whether rare or common, more or less fruitful, regularly keeps within such limits as to its numerical increase as are far, infinitely far, removed from a deficiency in the supply of food. I go further: you not merely know that this is so--you know also that it must be so, and why it must be so. Careful observation of natural events teaches you that a species which regularly increased to the very limit of the food-supply, and was, therefore, regularly exposed to hunger and privations, must necessarily degenerate--nay, you cannot fail to see that to many kinds of animals such an increase to the limit of the food-supply would mean sudden destruction. For the animals sow not, neither do they reap; they do not store up provisions for the satisfaction of future needs: and if at any time they were obliged to consume all the food that nature had produced for them, they would thereby, as a rule, destroy the source of their future food-supply, and would not merely suffer hunger, but would all starve. You know, therefore, that that inexhaustible abundance which, in contrast to the misery of human society, everywhere prevails in nature, and which, because of this contrast, the thinkers and poets of all ages have spoken and sung about, is not due to accident, but to necessity; and it only remains now to discover that natural process, that causal connection, by virtue of which this state of things necessarily exists. Upon this point men were treated to nothing but vague phrases when Malthus lived. The veil which hid the history of the evolution of the organic world had not then been lifted; men were therefore obliged to content themselves with explaining all that took place in the kingdoms of animals and plants as the work of Providence or of the so-called vital force--which naturally even then prevented no one from seeing and understanding the fact as well as the necessity of this formerly inexplicable natural phenomenon. But you, living in the century of Darwin, cannot for a moment entertain any doubt upon this last point. You know that it is through the struggle for existence that the living beings have developed into what they are--that properties which prove to be useful and essential to the well-being of a species are called forth, perfected, and fixed by this struggle; and, on the other hand, properties which prove to be detrimental to the well-being of a species are suppressed and removed. Now, since the property of never increasing to the limit of the food-supply is not only advantageous but absolutely necessary to the well-being--nay, to the existence--of every species, it must have been called forth, perfected, and fixed as a permanent specific character by the struggle for existence. You knew all this, my friends, before I said it; but this knowledge was so consciously present to your mind as to be of use in the process of thinking only when purely botanical or zoological questions were under consideration: as soon as in your organ of thought the strings of social or economic problems were struck, there fell a thick, opaque veil over this knowledge which was so clear before. The world no longer appeared to you as it is, but as it looks through the said veil of acquired prejudices and false notions; and your judgment no longer obeyed those universal laws which, under the name of 'logic,' in other cases compelled your respect, but indulged in singular capers which--if the said veil had not fallen over your senses--could not have failed to make you laugh. Indeed, so accustomed have you become to mistake the pictures which this veil shows to you for the actual world that you are not able to free yourselves from them even after you have roused yourselves to tear the veil in pieces. The false notions and erroneous conclusions of the Malthusian theory arose from the fact that its author was not able to discover the true source of the misery of mankind. He asked himself why did the Irish peasant and the Egyptian fellah suffer hunger? He was prevented by the above-mentioned veil from seeing that they suffered hunger because the produce of their labour was taken away from them--because, in fact, they were not permitted to labour. But he perceived that the masses everywhere and always suffered hunger--in some places and at some times less severely than in other places and at other times: yet, in spite of all their painful toil and industry, they perpetually suffered hunger, and had done so from time immemorial. Hence he at last came to the conclusion that this universal hungering was a consequence of a natural law. He further concluded that the fellah and the Irish peasant and the peoples of all parts of the world and of all times had suffered and still suffer hunger because there are too many of them; and there are too many of them because it is only hunger that prevents them from becoming still more numerous. That the world, perplexed by the enigma of misery, should believe this becomes intelligible when one reflects that misery must have a cause, and erroneous explanations must obtain credence when right ones are wanting. But it is remarkable, my friends, that you, who have recognised in exploitation and servitude the causes of misery, should still believe in that strange natural law which Malthus invented for the purpose of constructing out of it the above-mentioned makeshift. This means that, though you have torn the veil in pieces, your mind and your senses are still enveloped in its tatters. You have released yourselves sufficiently to see why the fellah and the Irish peasant suffer hunger to-day, but you tremble in fear that our posterity will have to endure the horrors of over-population. You still see the herring threatened with starvation, and the elephant wandering with an empty stomach over the bare-eaten forest-lands of Hindostan and Africa; and you pass in thought from the herring and the elephant to our poor over-populated posterity.

Tremendous applause burst forth from all parts of the hall when Dr. Strahl had finished. As he passed from the speaker's tribune to the President's chair, he was cordially shaken by the hand, not only by his friends who crowded around him, but also by the leaders of the Opposition, who gladly and unreservedly acknowledged themselves convinced. The excitement was so great that it was some time before the debate could be resumed. At last the President obtained a hearing for one of the previous speakers.

Robert Murchison (Right): I rise for the second time, on behalf of those who sit near me, first to declare that we are fully and definitively convinced. You will readily believe that we do not regret our defeat, but are honestly and heartily glad of it. Who would not be glad to discover that a dreadful figure which filled him with terror and alarm was nothing but a scarecrow? And even a sense of shame has been spared us by the magnanimity of the leader of the opposite party, who laid emphasis upon the fact that not merely we, but even his adherents outside of Freeland, still cherished in their hearts the same foolish anxiety, begotten of acquired and hereditary prejudices and false notions. The phantoms fled before his clear words, our laughter follows them as they flee, and we now breathe freely. But, if we might still rely upon the magnanimity of the happy dwellers in Freeland, the after-effects of the anxiety we have endured still linger in us. We are like children who have been happily talked out of our foolish dread of the 'black man,' but who nevertheless do not like to be left alone in the dark. We would beg you to let your light shine into a few dark corners out of which we cannot clearly see our way. Do not despise us if we still secretly believe a little in the black man. We will not forget that he is merely a bugbear; but it will pacify us to hear from your own mouths what the true and natural facts of the case are. In the first place, what are, in your opinion, the means employed by nature, in the struggle for the existence of species, to keep the growth of numbers from reaching the limit of the food-supply? Understand, we ask this time merely for an expression of opinion--of course, you cannot, any more than anyone else, know certainly how this has been done and is being done in individual cases; and if your answer should happen to be simply, 'We have formed no definite opinion upon the subject,' we should not on that account entertain any doubt whatever as to the self-evident truth that every living being possesses the characteristic in question, and that the origin of that characteristic must be sought somewhere in the struggle for existence. In order to be convinced that the stag has acquired his fleetness, the lion his strength, the fox his cunning, in the struggle for existence, it is not necessary for us to know exactly how this has come about; yet it is well to hear the opinions as to such subjects of men who have evidently thought much about them. Therefore we ask for your opinions on the question of the power of adaptation in fecundity.

Lothar Wallace (Freeland): We think that the characteristic in question, as it is common to all organisms, must have been acquired in a very early stage of evolution of the organic world; from which it follows that we are scarcely able to form definite conceptions of the details of the struggle for existence of those times--as, for example, of the process of evolution to which the stag owes his swiftness. We can only say in general that between fecundity and the death-rate an equilibrium must have been established through the agency of the mode of living. A species threatened with extinction would increase its fecundity or (by changing its habits) diminish its death-rate; whilst, on the other hand, a species threatened with a too rapid increase would diminish its fecundity or (again by changing its habits) increase its death-rate. Naturally the death-rate in question is not supposed to depend upon merely sickness and old age, but to be due in part to external dangers. The great fecundity, for example, of the heiring would, according to this view, be both cause and effect of its habits of life, which exposed it in its migrations to enormous destruction. Whether the herring and other migratory fishes adopted their present habits because of their exceptional fecundity--the origin of which would then have to be sought in some other natural cause--or whether those habits were originally due to some other cause, and provoked their exceptional fecundity, we cannot tell. But that a relation of action and reaction exists and must necessarily exist here is evident, since a species whose death-rate is increased by an increase of danger must die out if this increase of death-rate is not accompanied by an increased fecundity; and, in the same way, increased fecundity, when not followed by an increased death-rate, must in a short time lead to deterioration. At any rate, it can be shown that, whether deterioration or extermination has been the agent, species have died out; and it can be inferred thence that some species do not possess this power of effecting an equilibrium between fecundity and death-rate. But this conclusion would be too hasty a one. All natural processes of adaptation take place very gradually; and if a violent change in external relations suddenly produces a very considerable increase in the death-rate, it may be that the species cannot adapt its fecundity to the new circumstances rapidly enough to save itself from destruction. To infer thence that the species in question did not possess this power of adaptation at all would be as great a mistake as it would be to argue that, for example, because the stag, or the lion, or the fox, notwithstanding their fleetness, strength, or cunning, are not protected from extermination in the face of overpowering dangers, therefore these beasts do not possess swiftness, strength, or cunning, or that these properties of theirs are not the outcome of an adaptation to dangers called forth in the struggle for existence.

Since there can be no doubt that the power of adaptation, of which we have just spoken, was absolutely necessary to the perpetuation of any species in the struggle for existence in the very beginning of organic life upon our planet, it must have been acquired in immemorial antiquity, and must consequently be a part of the ancient heritage of all existing organisms. There certainly was a time, in the very beginning of life, when this power of adaptation was not yet acquired; but nature has an infallible means of making not only useful but necessary characters the common property of posterity, and this means is the extirpation of species incapable of such a power of adaptation. The selection in the struggle for existence is effected by the preservation of those only who are capable of development and of transmitting their acquired characters to posterity until those characters become fixed, such individuals as revert to the former condition being exterminated as they appear.

The reciprocal adaptation of fecundity to death-rate has thus belonged unquestionably for a long time to the specific character of all existing species without exception. Its presence is manifested not merely in the great universal fact that all species, despite many varying dangers--leaving out of view sudden external catastrophes and attacks of special violence--are preserved from either extermination or deterioration, but also in isolated phenomena which afford a more intimate glimpse into the physiological processes upon which the adaptation in question depends. Human knowledge does not yet extend very far in this direction, but accident and investigation have already given us a few hints. Thus, for example, we know that, as a rule, high feeding diminishes the fecundity of animals; stallions, bulls, etc., must not become fat or their procreative power is lessened, and the same has been observed in a number of female animals. As to man, it has long been observed that the poor are more fruitful than the rich, and, as a rule, notwithstanding the much greater mortality of their children, bring up larger families. The word 'proletarian' is derived from this phenomenon as it was known to the Romans; in England, Switzerland, and in several other countries the upper classes--that is, the rich--living in ease and abundance, have relatively fewer children--nay, to a great extent decrease in numbers. The census statistics in civilised countries show a general inverse ratio between national wealth and the growth of the population--a fact which, however, will be misinterpreted unless one carefully avoids confounding the wealth of certain classes in a nation with the average level of prosperity, which alone has to be taken into account here. In Europe, Russia takes the lead in the rate of growth of population, and is without question in one sense the poorest country in Europe. France stands lowest, the country which for more than a century has exhibited the most equable distribution of prosperity. That the English population increases more rapidly, though the total wealth of England is at least equal to that of France, is explained by the unequal distribution of its wealth. Moreover, it is not merely wealth that influences the growth of population--the ways in which the wealth is employed appear to have something to do with it. In the United States of America, for example, we find--apart from immigration--a large increase with an average high degree of prosperity, offering thus an apparent exception to our rule. Yet if we bear in mind the national character of the Yankees, excitable and incapable of calm enjoyment, the exception is sufficiently explained, and it is brought into harmony with the above principle. But the study of this subject is still in its infancy, and we cannot expect to see it clearly in its whole complex; nevertheless the facts already known show that the connection between the habits and life of fecundity is universally operative.

John Vuketich (Right): Certain phenomena connected with variations in population appear, however, to contradict the principles that disastrous circumstances act as stimuli to fecundity. For example, the fact that the number of births suddenly increases after a war or an epidemic, in short when the population has been decimated by any calamity, is to be explained by the sudden increase in the relative food-supply on account of the diminution of the number of the people. In this case, the greater facility of supplying one's wants produces a result which our theory teaches us to expect from a greater difficulty in doing so.

Jan Velden (Right): I know that this is the customary explanation of the well-known phenomenon just mentioned, and I must admit that an hour ago I should have accepted this explanation as plausible. Now, however, I do not hesitate to pronounce it absurd. Or can we really allow it to be maintained that, after a war or an epidemic, it is easier to get a living, wealth is greater, than before these misfortunes? I think that generally the contrary is the fact; after wars and epidemics men are more miserable than before, and on that account, and not because it is easier to get a living, their fecundity increases.
