“Marx wrote tirelessly until he died, producing hundreds of books, monographs and articles.”
—How many sentences, total, did Marx write which involved Darwin? Three? That’s all I can currently find... in two separate statements, both in private letters (of which there are many hundreds, consisting of thousands of pages). Was there anything public?
Some “seizing”.
“Darwin, whom I am just now reading, is splendid.”—Engles
“This is the book (Origins) which contains the basis in natural history for our view.”—Marx
“Darwin’s book is very important and serves me as a basis in natural science for the class struggle in history.”—Marx
Marx sent a personally inscribed copy of Das Kapital (calling himself a “sincere admirer”) to Darwin.
“Just as Darwin discovered the law of evolution in organic nature, so Marx discovered the law of evolution in human history”—Engles
“He (Darwin) dealt the metaphysical conception of nature the heaviest blow by his proof that the organic world of today — plants, animals, and consequently man too — is the product of a process of evolution going on through millions of years.”—Engles
“Marx admired Darwin’s book not for economic reasons but for the more fundamental one that Darwin’s universe was purely materialistic, and the explication of it no longer involved any reference to unobservable, nonmaterial causes outside or ‘beyond’ it. In that important respect, Darwin and Marx were truly comrades.”—Tom Bethel (senior editor, American Spectator).
