"It is not the consciousness of men which determines their existence, but, on the contrary, their social existence determines their consciousness."—(Marx, Preface to "Critique of Political Economy.")
Man, even the most heroic, is not the sovereign maker and law-giver of social life, but its executive; he only follows out the tendencies and currents set up by the material foundation of society. Nevertheless, a great deal depends upon the executive officials. If they possess comprehensive knowledge, energetic natures, and outstanding capacities, they are able, within the boundaries drawn for them, to accomplish great things, and to accelerate the development.
"Up to the present the philosophers have but interpreted the world; it is, however, necessary to change it."—(Marx, "Theses to Feuerbach.")
We have referred in various places to interests. We are not to understand by this personal, but general social or class interests. Marx is not of the opinion that everybody acts in accordance with his personal welfare. This is not Marxian doctrine, but that of the middle-class moral philosophers, like Helvetius (1715-1771) and Jeremy Bentham (1748-1832), who regarded pleasure and pain of the individual as the measure and motive of his actions and conduct. Marx is rather of the opinion that men often, in the most important events of their lives, act contrary to their personal interests, as in their feelings and thoughts they identify themselves with that which they hold to be the interests of the community or of their class. According to Marx, individual interest generally plays a slight part in history. He is preoccupied with the collective interest of social production. Only the latter does he hold to be determining in the formation of the intellectual superstructure.
Up till now we have only spoken of various forms of production and society, and their corresponding mental systems. But we do not yet know why and how one form of production and society becomes obsolete and gives place to another, that is, how and why revolutionary changes are brought about. Or in other words: we have hitherto considered the statics of society; we will now look at its dynamics.
The revolutionary changes in society depend on two groups of phenomena, which, although casually connected with each other, yet work differently. One of these groups of phenomena is technical, and consists in changes in the productive forces. The other group, which is the effect of the first, is of a personal nature, and consists in struggles between the social classes. Let us consider the first group of causes.
As the productive forces expand, through greater skill on the part of the worker, through discoveries of new raw material and markets, through the invention of new labour processes, tools and machines, and through the better organisation of trade and exchange, so that the material basis or the economic foundation of society is altered, then the old conditions of production cease to promote the interests of production. For the conditions of production: the former social classes, the former laws, State institutions, and intellectual systems were adapted to a state of the productive forces which is either in process of disappearing, or no longer exists. The social and intellectual superstructure no longer corresponds to the economic foundation. The productive forces and the conditions of production come into conflict with each other.
This conflict between the new realty and the old form, this conflict between new causes and the obsolete effects of bygone causes, begins gradually to influence the thoughts of men. Men commence to feel that they are confronted with a new external world, and that a new era has been opened.
Social divisions acquire a new significance: classes and sections which were formerly despised gain in social and economic power; classes which were formerly honoured decline. While this transformation of the social foundation is proceeding, the old religious, legal, philosophical, and political systems cling to their inherited positions, and insist on remaining, although they are obsolete and can no longer satisfy mental needs. For human thought is conservative: it follows external events slowly, just as our eye perceives the sun at a point which the sun has in reality already passed, as the rays require several minutes of time in order to strike our optic nerves. We may recall Hegel's fine metaphor: "The Owl of Minerva begins its flight only when twilight gathers." However late, it does begin. Great thinkers gradually arise, who explain the new situation, and create new ideas and trains of thought which correspond to the new situation. The human consciousness gives birth to anxious doubts and questionings, and then new truths; leading to differences of opinion, disputes, strifes, schisms, class struggles, and revolutions.
In the next chapter we will consider more closely the class struggle between Labour and Capital. Meanwhile, we will look at the class struggle generally.
