Historical materialist

Historical materialism is a methodological approach to the study of human societies and their development over time that was first articulated by Karl Marx (1818–1883) as the materialist conception of history. It is principally a theory of history according to which the material conditions of a society's way of producing and reproducing the means of human existence or, in Marxist terms, the union of its productive capacity and social relations of production, fundamentally determine its organization and development.

Historical materialism looks for the causes of developments and changes in human society in the means by which humans collectively produce the necessities of life. Social classes and the relationship between them, along with the political structures and ways of thinking in society, are founded on and reflect contemporary economic activity.

Since Marx's time, the theory has been modified and expanded by Marxist writers. It now has many Marxist and non-Marxist variants.

"In the Marxian view, human history is like a river. From any given vantage point, a river looks much the same day after day. But actually it is constantly flowing and changing, crumbling its banks, widening and deepening its channel. The water seen one day is never the same as that seen the next. Some of it is constantly being evaporated and drawn up, to return as rain. From year to year these changes may be scarcely perceptible. But one day, when the banks are thoroughly weakened and the rains long and heavy, the river floods, bursts its banks, and may take a new course. This represents the dialectical part of Marx's famous theory of dialectical (or historical) materialism."

Historical materialism springs from a fundamental underlying reality of human existence: that in order for human beings to survive and continue existence from generation to generation, it is necessary for them to produce and reproduce the material requirements of life. Marx then extended this premise by asserting the importance of the fact that, in order to carry out production and exchange, people have to enter into very definite social relations, most fundamentally "production relations".

However, production does not get carried out in the abstract, or by entering into arbitrary or random relations chosen at will. Human beings collectively work on nature but do not do the same work; there is a division of labor in which people not only do different jobs, but according to Marxist theory, some people live off the fruits of others' labor by owning the means of production. How this is accomplished depends on the type of society. Production is carried out through very definite relations between people. And, in turn, these production relations are determined by the level and character of the productive forces that are present at any given time in history. For Marx, productive forces refer to the means of production such as the tools, instruments, technology, land, raw materials, and human knowledge and abilities in terms of using these means of production.
