the seventies and eighties." Of course the Blind Chance doctrine breaks down utterly when it comes to be applied to selected cases, and nothing more definitely disposes of it than the very definite law which emerges as the result of the Mendelian experiments. That is obvious to the prophets of Mendelism; but, whilst they admit this, they will have nothing to say to the lawgiver. That is the "rankest metaphysics," as Dr. Johnstone puts it,[8] or "mysticism," as others prefer to call it. And yet nothing is more clear than the logical sequence that, if you have a law, someone must have made it, and if you look upon something as "a phenomenon of arrangement," someone must have arranged it. But for reasons not obvious nor confessed, there is an objection to make any such admission. Perhaps it is the taint of the monism of the latter half of the last century which still persists.

At any rate, as I have elsewhere pointed out, there is a most curious passage in another paper by the same author in which he says: "With the experimental proof that variation consists largely in the unpacking and repacking of an original complexity, it is not so certain as we might like to think that the order of these events is not pre-determined." The writer hastens to denounce the horrid heresy on the brink of which he finds himself hesitating, by adding that he sees "no ground whatever for holding such a view," though "in the light of modern research it scarcely looks so absurdly improbable as before."[9] It is curious that the writer in question does not seem to have been in any way influenced by the eliminative argument so potent in connection with the discussion on Vitalism. We ask for an explanation of the occurrences—say of regeneration. We find that no physical explanation in the least meets the needs of the case, and we are consequently obliged to look for it in something differing from the operations of chemistry and physics. Of this argument Dr. Johnstone[10] says: "It is almost impossible to overestimate the appeal which it makes to the investigator."

Now, this matter of "arrangement" or of "pre-determination," when put forward as an explanation, even tentatively, necessitates a step further. That step might possibly be in the direction of pantheism, though, according to Driesch,[11] pantheism is the doctrine "that reality is a something which makes itself ('dieu se fait,' in the words of Bergson), whilst theism would be any theory according to which the manifoldness of material reality is predetermined in an immaterial way." And he concludes "that those who regard the thesis of the theory of order as necessary for everything that is or can be, must accept theism, and are not allowed to speak of 'dieu qui se fait.'" It is difficult to see how anyone who has studied the rigid order exhibited by experiments on Mendelian lines can resist the logic of this argument unless indeed he takes a place on Plate's platform, which admits that a law entails a lawgiver, but declares that of the Lawgiver of Natural Laws we can know nothing.[12]

There is a further point in connection with Mendelian theories which is worth noting in this connection. It would appear that no new factor is ever brought into being, that is, no addition is ever made by variation. According to this theory the things which appear to be added—a new colour or a new scent—were there all the time. They were "stopped down" or inhibited by some other factor, which, when eliminated, allows them to come into play, and thus to become obvious to the observer from whom they had been hidden. Thus, Professor Bateson (M., p. 17) has confidence "that the artistic gifts of mankind will prove to be due, not to something added to the make-up of an ordinary man, but to the absence of factors which in the normal person inhibit the development of these gifts. They are almost beyond doubt to be looked upon as releases of powers normally suppressed. The instrument is there, but it is 'stopped down.'"

That all sorts of things may exist in a very small compass no doubt is true. Professor Bateson reminds us that Shakespeare was once "a speck of protoplasm not so big as a small pin's head." The difficulty—insuperable on ordinary monistic lines—is how all these things got into the germ if no additions ever take place. It was so difficult to account, for example, for artistic appreciation on the part of man or for gifts of an artistic character that Huxley was fain to describe them as gratuitous; but on this showing all characters are gratuitous in the sense that they are not acquired. We may reasonably inquire not merely how all these characters and factors got themselves "arranged" or "packed," but where they came from, and how they came to be in the germ at all, matters on which we receive no information in these addresses. No doubt the author of the addresses would say that it was no part of his business to explain this matter; that he took this system of Nature as a going system and did his best to explain it as such and without attempting, perhaps even without desiring, to explain how it got a-going. If that be the case, and if ignorance on this head must be his confession, it is a little difficult to understand the confidence with which he sets himself to discuss the "extraordinary and far-reaching changes in public opinion [which] are coming to pass." We shall find these, as we pass them in review, to be extraordinary enough, though not very new.

In the first place, "genetic research will make it possible for a nation to elect by what sort of beings it will be represented not very many generations hence, much as a farmer can decide whether his byres shall be full of shorthorns or Herefords. It will be very surprising indeed if some nation does not make trial of this new power. They may make awful mistakes, but I think they will try" (S., p. 8). It is curious how the war, which had just commenced when these addresses were being delivered, has absolutely disposed, or ought to have disposed, of some of the prophecies of the President. Nothing, at any rate, seems more certain than that one result of this most disastrous struggle will be an urgent demand by all the States engaged in it for at least as many male children as the mothers of each country can supply, without special regard to their other characters, breedable or not breedable. We are even told that Germany is resorting to expedients which cannot be justified on Christian principles to fill her depleted homes. Whether this be true or not the fact remains that nothing is now more to be desired by all the combatant nations than what we call in Ireland "long families." But even if there had been no war, there is one other factor which makes it quite certain that no country ever will try, or if it ventures to try, will ever succeed in any such experiment, and that factor, forgotten by philosophers of this kind, is human nature. Mr. Frankfort Moore years ago wrote a pleasant story, called "The Marriage Lease," in which doctrinaire legislation of a somewhat similar kind was described, and its inevitable failure most amusingly depicted. The war disposes of another of the President's maxims (S., p. 10), that the decline in the birth-rate of a country is nothing to be grieved about, and that "the slightest acquaintance with biology" shows that the "inference may be wholly wrong," which asserts that "a nation in which population is not rapidly increasing must be in a decline" (S., p. 10). Human nature was neglected in the first-mentioned case, and here it is the turn of history to pass into the shade, history which, pace the President, has really a good deal more bearing upon a question of this kind than the "school-boy natural history" which he thinks capable of settling it. Thus we advance from breeding to Malthusianism. It is perhaps not wonderful that our next step should be the quiet, and of course painless, extinction of the unfit.
