Steinmann declares it to be the primary task of post-Darwinian palaeontology "to arrange the fossil animal and plant-remains in the order of descent and thus to build up a truly natural, because historically demonstrable, classification of the animal and plant-world."
That he could, in a recent volume of the “Biologisches Zentralblatt,” write a respectful and sympathetic exposition of the Hegelian nature-philosophy—as regards its aims, though not its methods—is as remarkable a symptom as we can instance of the modern trend of views and opinions. Contrast Between Darwinian and Post-Darwinian Views.
He paused again, holding his pipe in his hand, unlit, and looking before him with wide eyes. "I respect that as much as anyone can," said Dyce, gravely. "As much as anyone can who doesn't believe it." His father took him up with gentle irony. "I don't expect the impossible. You cannot believe in it; for you were born a post-Darwinian. Well, your religion is temporal; let us take that for granted.
In respect of the great problems of Philosophy, the post-Darwinian generation is, in one sense, exactly where the prae-Darwinian generations were. They remain insoluble. But the present generation has the advantage of being better provided with the means of freeing itself from the tyranny of certain sham solutions.
The laws of biological inheritance have received close and deep study by numerous investigators of Darwinian and post-Darwinian times, because from the first it was clearly recognized that a complete description of nature's method of accomplishing evolution must show how species maintain the same general characteristics from generation to generation, and also how new qualities may be fixed in heredity as species transform in the course of time.
This was claimed not only by reason of the best anatomical research, but to be "deducible from the whole trend of geological and anthropological discovery." On this account Professor Wood-Jones appealed for "an entire reconsideration of the post-Darwinian conceptions of man's comparatively recent emergence from the brute kingdom."
In these post-Darwinian days, moreover, we are inclined to give way to certain morbid and sentimental exaggerations of sympathy, which do some injustice to the great Artificer whom we are for the moment assuming to be responsible for sentient life. Many of us are much concerned about "nature, red in tooth and claw."
Before proceeding to the post-Darwinian investigations that have done so much to amplify the account of natural evolution, let us consider the contrasted explanation given by Lamarck and his followers.
Beyond these the same animistic sense shows itself also in such attenuations of anthropomorphism as the eighteenth-century appeal to an order of nature and natural rights, and in their modern representative, the ostensibly post-Darwinian concept of a meliorative trend in the process of evolution.
From what has been said of these post-Darwinian discoveries, the Lamarckian doctrine, which teaches that acquired non-congenital characters are transmitted, seems to be ruled out. I would not lead you to believe that the matter is settled.
