THE PROBLEM OF THE BIRTH SUPPLY

But the use of the word "Survival" should have sufficed to indicate that the real point of application of the force by which Nature modifies species and raises the average in any quality, lies not in selective breeding, but in the disproportionately numerous deaths of the individuals below the average. And even the methods of the breeder of cattle, if they are to produce a permanent alteration in the species of cattle, must consist not only in breeding the desirable, but in either killing the undesirable, or at least—what is the quintessence, the inner reality of death—in preventing them from breeding.
The general trend of thought in Mrs. Martin's Humanitarian was certainly more in accordance with this reading of biological science than were Mr. Galton's proposals. There was a much greater insistence upon the need of "elimination," upon the evil of the "Rapid Multiplication of the Unfit," a word that, however, was never defined and, I believe, really did not mean anything in particular in this connection. And directly one does attempt to define it, directly one sits down in a businesslike way to apply the method of elimination instead of the method of selection, one is immediately confronted by almost as complex an entanglement of difficulties in defining points to breed out as one is by defining points to breed for. Almost, I say, but not quite. For here there do seem to be, if not certainties, at
