Biologists in general agree that in the present state of the world, no such thing happens as the rise of a living creature out of non-living matter.
A great astronomer, two eminent biologists, a famous botanist, a practical navigator, a geographer, all men of distinction among European savants, and two of them, Laplace and Cuvier, among the greatest men of science of modern times, were scholars who knew what might be expected to be gained for knowledge, and where and how the most fruitful results might be obtained.
The new discoveries suggest that we must insist equally upon the right environment and manner of life before pregnancy begins. This brings up a very interesting question upon which biologists are not agreed. Does what has just been said about the period before pregnancy apply to the father as well as the mother?
Those scientific arguments, biological and philological, may satisfy the biologists and the philologists; they certainly satisfy nobody else. All those pseudo-scientific facts belong to the realm of fiction.
If a foreigner may presume to speculate on the cause of this curious interval of silence, I fancy it was that one moiety of the German biologists were orthodox at any price, and the other moiety as distinctly heterodox.
This in itself was a new fact of extraordinary interest. For long, discussion had been waged between two departments of scientific inquirers. The geologists and biologists had demanded hundreds, and perhaps thousands, of millions of years to allow for the developments with which they were concerned.
The fine-spun, elaborate theories about sex, so current twenty years ago, have fallen into almost complete desuetude among scientists. With the discovery of the place of the chromosomes in inheritance, biologists began to give their almost undivided attention to a rigid laboratory examination of the cell.
May I be pardoned a personal account of this particular feature. It was my good fortune to be for a short time a student in a class taught by Edward Drinker Cope, one of the most brilliant of our American biologists. Prof. Upon such authority as this, I had no hesitancy whatever in repeating Cope's statement.
Both Huxley on the platform and Spencer in the "Nineteenth Century" had acknowledged before the whole world that they had lost faith in the idol which for thirty years they had so vociferously worshipped. It is true that both Spencer and Huxley might have intended to warn biologists merely against a too implicit faith in natural selection or the survival of the fittest.
Further, she has maintained that if we come to talk of a dangerous environment, the most dangerous environment of all is the commodious environment. I know that the most modern manufacture has been really occupied in trying to produce an abnormally large needle. I know that the most recent biologists have been chiefly anxious to discover a very small camel.
