In this book Georgi Plekhanov takes up three main themes: What historical materialism is, what competing theories of history say, and two specific relationships: being and thinking, and freedom and necessity. He shows how Marx's dialectical reasoning applies to them all.
The author defends the scientific basis of social research which, if done correctly, can explain man's social aims as a necessary consequence of a social process ultimately determined by economic development. Feuerbach had taken the study of mankind decisively out of the realm of metaphysics in his critique of Hegel's idealistic conception of history, but it took Marx to ground the study of man in reality -- that is, within its actual spatiotemporal context.
This is the origin of historical materialism. Though no science can rid a subject of every problem, historical materialism makes it much easier to deal with the difficulties inherent in the study of social relations. Marxists ask not just what, but how things happen. Asking how societies developed historically requires the dialectical method. The task of historical materialism, as Plekhanov sees it, is to explain in what manner "circumstances can be changed by those who are created by them."
The author considers various other theories of history, such as the that of "factors," and the idea of the hard determination of historical events. In respect to the view of history as a series of relatively independent or co-equal factors, he demonstrates how it is that Marx regards the economic factor as the ultimately decisive one.
With regard to the criticism that Marxism as "deterministic," that is, lacking any free agency, he shows how Marxism avoids that by considering subject and object as a unity, not an identity. Plekhanov notes that although such mind/body dualism had long ago been demolished, this discredited basis of determinism is reproduced constantly by vulgar thinkers using the same old arguments against Marxism. As he puts it, "the rat will never stop thinking that the cat is far stronger than the lion."
In discussing these issues Plekhanov reiterates that being is the source of thinking and upholds the scientific view, extending it as needed to show, for example that social being is the source of social thinking. A more important and related issue is that of freedom and necessity. The author's major task is to show how freedom of human action arises in a world of necessity, and he takes the subject up in detail. He explains the barrier dualism erects to an understanding of the two terms, and the role of conditional necessity in social action.
Plekanov was known for the effectiveness of his exposition of Marxism. Besides the main part of the book an appendix contains an 1897 lecture, about 35 pages, involving a broad discussion of what is and is not historical materialism. After that comes a shorter 1898 lecture on the role of the individual in history. It’s interesting to see what a Marxist living in the early 1900's thought was most necessary to explain to the public.
This is a well done discussion of some basic concepts in Marxism. I didn't give it five stars because some of the material is dated and some of the issues, like thinking and being, are old. On the other hand, Plekhanov argues strongly for "leaps" in dialectical development well in advance of modern science, as in Gould's theory of punctuated equilibrium. His refutation of the "factors" theory of historical development directly contradicts the prevailing notions of identity politics in modern bourgeois consciousness. Students of Marxism are free to read whatever they like, but this book is a necessity.
