Those who take this view hold that he knew how impossible it would be to get the nation to accept legislation that it held to be sinful; he knew also how hopeless it would be to convince people that it was not wicked to kill a sheep and eat it, unless he could show them that they must either sin to a certain extent, or die.  He, therefore, it is believed, made the monstrous proposals of which I will now speak.

He began by paying a tribute of profound respect to the old prophet, whose advocacy of the rights of animals, he admitted, had done much to soften the national character, and enlarge its views about the sanctity of life in general.  But he urged that times had now changed; the lesson of which the country had stood in need had been sufficiently learnt, while as regards vegetables much had become known that was not even suspected formerly, and which, if the nation was to persevere in that strict adherence to the highest moral principles which had been the secret of its prosperity hitherto, must necessitate a radical change in its attitude towards them.

It was indeed true that much was now known that had not been suspected formerly, for the people had had no foreign enemies, and, being both quick-witted and inquisitive into the mysteries of nature, had made extraordinary progress in all the many branches of art and science.  In the chief Erewhonian museum I was shown a microscope of considerable power, that was ascribed by the authorities to a date much about that of the philosopher of whom I am now speaking, and was even supposed by some to have been the instrument with which he had actually worked.

This philosopher was Professor of botany in the chief seat of learning then in Erewhon, and whether with the help of the microscope still preserved, or with another, had arrived at a conclusion now universally accepted among ourselves—­I mean, that all, both animals and plants, have had a common ancestry, and that hence the second should be deemed as much alive as the first.  He contended, therefore, that animals and plants were cousins, and would have been seen to be so, all along, if people had not made an arbitrary and unreasonable division between what they chose to call the animal and vegetable kingdoms.

He declared, and demonstrated to the satisfaction of all those who were able to form an opinion upon the subject, that there is no difference appreciable either by the eye, or by any other test, between a germ that will develop into an oak, a vine, a rose, and one that (given its accustomed surroundings) will become a mouse, an elephant, or a man.

He contended that the course of any germ’s development was dictated by the habits of the germs from which it was descended and of whose identity it had once formed part.  If a germ found itself placed as the germs in the line of its ancestry were placed, it would do as its ancestors had done, and grow up into the same kind of organism as theirs.  If it found the circumstances only a little different, it would make shift (successfully or unsuccessfully) to modify its development accordingly; if the circumstances were widely different, it would die, probably without an effort at self-adaptation.  This, he argued, applied equally to the germs of plants and of animals.
