In assigning the lion's share of development to the accumulation of fortunate accidents, he tempted fortuitists to try to cut the ground from under Lamarck's feet by denying that the effects of use and disuse can be inherited at all. When the public had once got to understand what Lamarck had intended, and wherein Mr.
And when will this theory, the hardihood of which has been greatly exaggerated, become freed from the interpretations and commentaries by the false light of which so many naturalists have followed their opinion concerning it? In 1873 M. Martin published his edition of Lamarck's Philosophic Zoologique. Professor Huxley in his article on Evolution is no less cavalier than Mr. Wallace.
Darwin's strongly-based hypothesis is nothing but a mere modification of Lamarck's, you will know what to think of their capacity for forming a judgment on this subject. But you must recollect that when I say I think it is either Mr.
Since Lamarck's time, almost all competent naturalists have left speculations on the origin of species to such dreamers as the author of the "Vestiges," by whose well-intentioned efforts the Lamarckian theory received its final condemnation in the minds of all sound thinkers.
He was very kind-hearted, and thoroughly liberal in his religious beliefs, or rather disbeliefs; but he was a strong theist. His candour was highly remarkable. He exhibited this by becoming a convert to the Descent theory, though he had gained much fame by opposing Lamarck's views, and this after he had grown old.
Though Lamarck's way, the way of life, will, aspiration, and achievement, remained still possible, this newly shewn way of hunger, death, stupidity, delusion, chance, and bare survival was also possible: was indeed most certainly the way in which many apparently intelligently designed transformations had actually come to pass.

Herbert Spencer, for example, "repeatedly and easily refute" Lamarck's hypothesis in his brilliant article in the Leader, March 20, 1852? On the contrary, that article is expressly directed against those "who cavalierly reject the hypothesis of Lamarck and his followers." This article was written six years before the words last quoted from Mr.
Men who had found Lamarck's conception of change through voluntary effort ridiculous, and the vaporings of the Vestiges altogether despicable, men whose scientific cautions held them back from Spencer's deductive argument, took eager hold of that tangible, ever-present principle of natural selection, and were led on and on to its goal.
"Lamarck held, as people in all ages have held, that characters acquired by parents are also transmissible to some extent, and that evolution results from their accentuation during succeeding generations. Lamarck's theory is rejected totally by the modern followers of Darwin. "Ten thousand men might break their fingers, yet among their offspring not one might have a crooked finger.
