p It is common knowledge that, in any given society, the strivings of some of its members conflict with the strivings of others, that social life is full of contradictions, and that history reveals a struggle between nations and societies, as well as within nations and societies, and, besides, an alternation of periods of revolution and reaction, peace and war, stagnation and rapid progress or decline. Marxism has provided the guidance, i.e., the theory of the class struggle, for the discovery of the laws governing this seeming maze and chaos. It is only a study of the sum of the strivings of 21 all the members of a given society or group of societies that can lead to a scientific definition of the result of those strivings. Now the conflicting strivings stem from the difference in the position and mode of life of the classes into which each society is divided. "The history of all hitherto existing society is the history of class struggles," Marx wrote in the Communist Manifesto (with the exception of the history of the primitive community, Engels added subsequently). "Freeman and slave, patrician and plebeian, lord and serf, guild-master and journeyman, in a word, oppressor and oppressed, stood in constant opposition to one another, carried on an uninterrupted, now hidden, now open fight, a fight that each time ended, either in a revolutionary re-constitution of society at large, or in the common ruin of the contending classes—The modern bourgeois society that has sprouted from the ruins of feudal society has not done away with class antagonisms. It has but established new classes, new conditions of oppression, new forms of struggle in place of the old ones. Our epoch, the epoch of the bourgeoisie, possesses, however, this distinctive feature: it has simplified the class antagonisms. Society as a whole is more and more splitting up into two great hostile camps, into two great classes directly facing each other: Bourgeoisie and Proletariat." Ever since the Great French Revolution, European history has, in a number of countries, tellingly revealed what actually lies at the bottom of events— the struggle of classes. The Restoration^^15^^ period in France already produced a number of historians (Thierry, Guizot, Mignet, and Thiers) who, in summing up what was taking place, were obliged to admit that the class struggle was the key to all French history. The modern period—that of the complete victory of the bourgeoisie, representative institutions, extensive (if not universal) suffrage, a cheap daily press, that is widely circulated among the masses, etc., a period of powerful and ever-expanding unions of workers and unions of employers, etc.—has shown even more strikingly (though sometimes in a very one-sided, “peaceful” and “constitutional” form) the class struggle as the mainspring of events. The following passage from Marx’s Communist Manifesto will show us what Marx demanded of social science as regards an objective analysis of the position of 22 each class in modern society, with reference to an analysis of each class’s conditions of development: "Of all the classes that stand face to face with the bourgeoisie today, the proletariat alone is a really revolutionary class. The other classes decay and finally disappear in the face of Modern Industry; the proletariat is its special and essential product. The lower middle class, the small manufacturer, the shopkeeper, the artisan, the peasant, all these fight against the bourgeoisie, to save from extinction their existence as fractions of the middle class. They are therefore not revolutionary, but conservative. Nay more, they are reactionary, for they try to roll back the wheel of history. If by chance they are revolutionary, they are so only in view of their impending transfer into the proletariat; they thus defend not their present, but their future interests; they desert their own standpoint to place themselves at that of the proletariat." In a number of historical works (see Bibliography), Marx gave brilliant and profound examples of materialist historiography, of an analysis of the position of each individual class, and sometimes of various groups or strata within a class, showing plainly why and how "every class struggle is a political struggle".^^16^^ The above-quoted passage is an illustration of what a complex network of social relations and transitional stages from one class to another, from the past to the future, was analysed by Marx so as to determine the resultant of historical development.

Marx’s economic doctrine is the most profound, comprehensive and detailed confirmation and application of his theory.
