“Note: One must study the position of Professor Lukács towards the philosophy of praxis. It would appear that Lukács maintains that one can speak of the dialectic only for the history of men and not for nature. He might be right and he might be wrong. If his assertion presupposes a dualism between nature and man he is wrong because he is falling into a conception of nature proper to religion and to Graeco-Christian philosophy and also to idealism which does not in reality succeed in unifying and relating man and nature to each other except verbally. But if human history should be conceived also as the history of nature (also by means of the history of science) how can the dialectic be separated from nature? Perhaps Lukács, in reaction to the baroque theories of the Popular Manual, has fallen into the opposite error, into a form of idealism.”

The Popular Manual Gramsci is referring to is Nikolai Bukharin’s Historical Materialism.

Gramsci is wrong here, yes? Compare the history of humanity with the history of, say, rabbits.
