For decades, the question of whether dialectics applies to nature has been a hotly debated topic in the Marxian literature. A number of authors have claimed that the Marxist outlook on nature and natural sciences has been for-mulated by Engels alone. According to this view, Marx, unlike Engels, was concerned not with trans-historical laws governing the universe but with some particular laws of society. This anti-Engels camp, so to speak, mainly tended to draw bold lines between Marx and Engels, and (...) charged Engels with dis-torting Marxʼs original ideas of dialectics by some kind of reductionism, sci-entism and positivism that might also end up in an obsolete idealism. Engels was „following Hegelʼs mistaken lead“ by extending „the method to apply also to nature“. However, dialectics was „limited ... to the realms of history and society“.2 Some others objected to this view, and characterized any at-tempt to sharply contrast Engels with Marx as concealed mysticism and idealism.

On the contrary, „it was worked out in collaboration with Marx and had his full agreement. (shrink)
