A glance over human history suffices to teach us that from age to age man has held to be true or false various opinions on rights, customs, religion, the State, philosophy, land-holding, trade, industry, etc., that he has had various economic arrangements, and forms of the State and of society, and that he has gone through an endless series of struggles and wars and migrations. How has this complicated variety of human thought and action come about? Marx raises that question, which, so far as he is concerned, does not aim in the first place at the discovery of the origin of thought, of rights, of religion, of society, of trade, etc.; these he takes to be historically given. He is rather concerned to find out the causes, the impulses, or the springs which produce the changes and revolutions of the essentials and forms of the mental and social phenomena, or which create the tendencies thereto. In a sentence: What interested Marx here was not the origin, but the development and change of things—he is searching for the dynamic law of history.
Marx answered: The prime motive power of human society, which is responsible for the changes of human consciousness and thought, or which causes the various social institutions and conflicts to arise, does not originate, in the first place, from thought, from the Idea, from the world-reason or the world-spirit, but from the material conditions of life. The basis of human history is therefore material. The material conditions of life—that is, the manner in which men as social beings, with the aid of environing nature, and of their own in-dwelling physical and intellectual qualities, shape their material life, provide for their sustenance, and produce, distribute and exchange the necessary goods for the satisfaction of their needs.
Of all categories of material conditions of existence, the most important is production of the necessary means of life. And this is determined by the nature of the productive forces. These are of two kinds: inanimate and personal. The inanimate productive forces are: soil, water, climate, raw materials, tools and machines. The personal productive forces are: the labourers, the inventors, discoverers, engineers, and finally, the qualities of the race—the inherited capacities of specific groups of men, which facilitate work.
The foremost place among the productive forces belongs to the manual and mental labourers; they are the real creators of exchange-value in capitalist society. The next place of importance is taken by modern technology, which is an eminently revolutionising force in society.—("Capital" (German), Vol. I., Chapters 1, 12, 13 and 14, "Poverty of Philosophy" (German edition, 1885, pp. 100-101.))
So much for the conception "Productive Forces," which plays an important part with Marx. We come now to the other equally important notion, "Conditions of production." By this phrase Marx understands the legal and State forms, ordinances and laws, as well as the grouping of social classes and sections: thus, the social conditions which regulate property and determine the reciprocal human relations in which production is carried on. The conditions of production are the work of men in society. Just as men produce various material goods out of the materials and forces made available to them by Nature, so they create out of the reactions of the productive forces upon the mind definite social, political, and legal institutions, as well as systems of religion, morals, and philosophy.
"Men make their own history, but do not so spontaneously in conditions chosen by them, but on the contrary, in conditions which they have found ready to hand transmitted and given."—(Marx, "The Eighteenth Brumaire," I.)
That is to say, under the influence of productive work and its needs, men build their form of society, their State, their religion, their philosophy and science. The material production is the substructure or the groundwork, while the corresponding political, religious, and philosophical systems are the superstructure. And in such a manner that the superstructure corresponds to the foundation, lends it strength, and promotes its development.
The foundation is material, and the superstructure is the psychical reflex and effect.
In broad outlines this conception may be illustrated somewhat as follows:
Primitive human groups lived under Communism and were organised according to blood relationship. Their deities have the characteristics of their natural environment, and reflect the physical effects of this environment upon the primitive mental life of the "savage"; their religion, their morality, and their laws promote the communal life and the tribal discipline. Feudal society is based on the possession of land by the nobles and on the industrial labour of the corporations of the towns. The inherited religious ideas are soon transformed in accordance with the dominant interests of these historical periods (primitive Christianity became a State religion); all religious, ethical, and philosophical ideas antagonistic to these interests were fought and persecuted. The middle-class society, which is based on personal property, is endeavouring to sweep away all vestiges of communal and corporation rights, to set free the individual, to mobilise labour and property, to abolish Feudalism and the old Church and monasterial institutions, and to put in their place the individual relation between man and God, or the personal conscience (the Reformation), introducing individual rights as well; it struggles against the independent sovereignty of the feudal domains, and labours for a united national territory, which will afford greater scope to trade and commerce; it supports Absolutism, so long as the latter is in conflict with the feudal lords; and when, afterwards, Absolutism is a hindrance to the development of middle-class society, this also is fought and a constitutional monarchy or a republic demanded. And all this takes place not because certain human intelligences, by reason of more intense thought, or enlightenment, or the call of a supernatural power, are primarily at work, but as a consequence of the influence of the material basis, of the economic foundation of society, upon the mind, which translates and transforms these external realities into religious, juridical, and philosophic conceptions:
