Karl Marx's (1818- 1883) thought was strongly influenced by :
Marx believed that he could study history and society scientifically and discern tendencies of history and the resulting outcome of social conflicts. Some followers of Marx concluded, therefore, that a communist revolution is inevitable. However, Marx famously asserted in the eleventh of his Theses on Feuerbach that "philosophers have only interpreted the world, in various ways; the point however is to change it", and he clearly dedicated himself to trying to alter the world. Consequently, most followers of Marx are not fatalists, but activists who believe that revolutionaries must organize social change.
Marx's view of history, which came to be called the materialist conception of history (and which was developed further as the philosophy of dialectical materialism) is certainly influenced by Hegel's claim that reality (and history) should be viewed dialectically. Hegel believed that the direction of human history is characterized in the movement from the fragmentary toward the complete and the real (which was also a movement towards greater and greater rationality). Sometimes, Hegel explained, this progressive unfolding of the Absolute involves gradual, evolutionary accretion but at other times requires discontinuous, revolutionary leaps - episodal upheavals against the existing status quo. For example, Hegel strongly opposed the ancient institution of legal slavery that was practiced in the United States during his lifetime, and he envisioned a time when Christian nations would radically eliminate it from their civilization. While Marx accepted this broad conception of history, Hegel was an idealist, and Marx sought to rewrite dialectics in materialist terms. He wrote that Hegelianism stood the movement of reality on its head, and that it was necessary to set it upon its feet. (Hegel's philosophy remained and remains in direct opposition to Marxism on this key point.)
Marx's acceptance of this notion of materialist dialectics which rejected Hegel's idealism was greatly influenced by Ludwig Feuerbach. In The Essence of Christianity, Feuerbach argued that God is really a creation of man and that the qualities people attribute to God are really qualities of humanity. Accordingly, Marx argued that it is the material world that is real and that our ideas of it are consequences, not causes, of the world. Thus, like Hegel and other philosophers, Marx distinguished between appearances and reality. But he did not believe that the material world hides from us the "real" world of the ideal; on the contrary, he thought that historically and socially specific ideologies prevented people from seeing the material conditions of their lives clearly.
The other important contribution to Marx's revision of Hegelianism was Engels' book, The Condition of the Working Class in England in 1844, which led Marx to conceive of the historical dialectic in terms of class conflict and to see the modern working class as the most progressive force for revolution.The notion of labour is fundamental in Marx's thought. Basically, Marx argued that it is human nature to transform nature, and he calls this process of transformation "labour" and the capacity to transform nature labour power. For Marx, this is a natural capacity for a physical activity, but it is intimately tied to the human mind and human imagination:A spider conducts operations that resemble those of a weaver, and a bee puts to shame many an architect in the construction of her cells. But what distinguishes the worst architect from the best of bees is this, that the architect raises his structure in imagination before he erects it in reality. (Capital, Vol. I, Chap. 7, Pt. 1) Karl Marx inherits that Hegelian dialectic and, with it, a disdain for the notion of an underlying invariant human nature. Sometimes Marxists express their views by contrasting "nature" with "history". Sometimes they use the phrase "existence precedes consciousness". The point, in either case, is that who a person is, is determined by where and when he is - social context takes precedence over innate behavior; or, in other words, one of the main features of human nature is adaptability. Marx did not believe that all people worked the same way, or that how one works is entirely personal and individual. Instead, he argued that work is a social activity and that the conditions and forms under and through which people work are socially determined and change over time.Marx's analysis of history is based on his distinction between the means / forces of production, literally those things, such as land, natural resources, and technology, that are necessary for the production of material goods, and the relations of production, in other words, the social and technical relationships people enter into as they acquire and use the means of production. Together these comprise the mode of production; Marx observed that within any given society the mode of production changes, and that European societies had progressed from a feudal mode of production to a capitalist mode of production. In general, Marx believed that the means of production change more rapidly than the relations of production (for example, we develop a new technology, such as the Internet, and only later do we develop laws to regulate that technology). For Marx this mismatch between (economic) base and (social) superstructure is a major source of social disruption and conflict. Marx understood the "social relations of production" to comprise not only relations among individuals, but between or among groups of people, or classes. As a scientist and materialist, Marx did not understand classes as purely subjective (in other words, groups of people who consciously identified with one another). He sought to define classes in terms of objective criteria, such as their access to resources. For Marx, different classes have divergent interests, which is another source of social disruption and conflict. Conflict between social classes being something which is inherent in all human history:The history of all hitherto existing society is the history of class struggles. (The Communist Manifesto, Chap. 1)
Marx was especially concerned with how people relate to that most fundamental resource of all, their own labour-power. Marx wrote extensively about this in terms of the problem of alienation. As with the dialectic, Marx began with a Hegelian notion of alienation but developed a more materialist conception. For Marx, the possibility that one may give up ownership of one's own labour - one's capacity to transform the world - is tantamount to being alienated from one's own nature; it is a spiritual loss. Marx described this loss in terms of commodity fetishism, in which the things that people produce, commodities, appear to have a life and movement of their own to which humans and their behavior merely adapt. This disguises the fact that the exchange and circulation of commodities really are the product and reflection of social relationships among people. Under capitalism, social relationships of production, such as among workers or between workers and capitalists, are mediated through commodities, including labor, that are bought and sold on the market.
Commodity fetishism is an example of what Engels called false consciousness, which is closely related to the understanding of ideology. By ideology they meant ideas that reflect the interests of a particular class at a particular time in history, but which are presented as universal and eternal. Marx and Engels' point was not only that such beliefs are at best half-truths; they serve an important political function. Put another way, the control that one class exercises over the means of production includes not only the production of food or manufactured goods; it includes the production of ideas as well (this provides one possible explanation for why members of a subordinate class may hold ideas contrary to their own interests). Thus, while such ideas may be false, they also reveal in coded form some truth about political relations. For example, although the belief that the things people produce are actually more productive than the people who produce them is literally absurd, it does reflect the fact (according to Marx and Engels) that people under capitalism are alienated from their own labour-power. Another example of this sort of analysis is Marx's understanding of religion, summed up in a passage from the preface to his 1843 Contribution to the Critique of Hegel's Philosophy of Right: Religious suffering is, at one and the same time, the expression of real suffering and a protest against real suffering. Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people. Whereas his Gymnasium senior thesis argued that the primary social function of religion was to promote solidarity, here Marx sees the social function as a way of expressing and coping with social inequality, thereby maintaining the status quo. Marx argued that this alienation of human work (and resulting commodity fetishism) is precisely the defining feature of capitalism. Prior to capitalism, markets existed in Europe where producers and merchants bought and sold commodities. According to Marx, a capitalist mode of production developed in Europe when labor itself became a commodity - when peasants became free to sell their own labor-power, and needed to do so because they no longer possessed their own land or tools necessary to produce. People sell their labor-power when they accept compensation in return for whatever work they do in a given period of time (in other words, they are not selling the product of their labor, but their capacity to work). In return for selling their labor power they receive money, which allows them to survive. Those who must sell their labor power to live are "proletarians." The person who buys the labor power, generally someone who does own the land and technology to produce, is a "capitalist" or "bourgeois." (Marx considered this an objective description of capitalism, distinct from any one of a variety of ideological claims of or about capitalism). The proletarians inevitably outnumber the capitalists.
Marx distinguished industrial capitalists from merchant capitalists. Merchants buy goods in one place and sell them in another; more precisely, they buy things in one market and sell them in another. Since the laws of supply and demand operate within given markets, there is often a difference between the price of a commodity in one market and another. Merchants, then, practice arbitrage, and hope to capture the difference between these two markets. According to Marx, capitalists, on the other hand, take advantage of the difference between the labor market and the market for whatever commodity is produced by the capitalist. Marx observed that in practically every successful industry input unit-costs are lower than output unit-prices. Marx called the difference "surplus value" and argued that this surplus value had its source in surplus labour.
The capitalist mode of production is capable of tremendous growth because the capitalist can, and has an incentive to, reinvest profits in new technologies. Marx considered the capitalist class to be the most revolutionary in history, because it constantly revolutionized the means of production. But Marx argued that capitalism was prone to periodic crises. He suggested that over time, capitalists would invest more and more in new technologies, and less and less in labor. Since Marx believed that surplus value appropriated from labor is the source of profits, he concluded that the rate of profit would fall even as the economy grew. When the rate of profit falls below a certain point, the result would be a recession or depression in which certain sectors of the economy would collapse. Marx understood that during such a crisis the price of labor would also fall, and eventually make possible the investment in new technologies and the growth of new sectors of the economy.
Marx believed that this cycle of growth, collapse, and growth would be punctuated by increasingly severe crises. Moreover, he believed that the long-term consequence of this process was necessarily the enrichment and empowerment of the capitalist class and the impoverishment of the proletariat. He believed that were the proletariat to seize the means of production, they would encourage social relations that would benefit everyone equally, and a system of production less vulnerable to periodic crises. In general, Marx thought that peaceful negotiation of this problem was impracticable, and that a massive, well-organized and violent revolution would in general be required, because the ruling class would not give up power without violence. He theorized that to establish the socialist system, a dictatorship of the proletariat - a period where the needs of the working-class, not of capital, will be the common deciding factor - must be created on a temporary basis. As he wrote in his "Critique of the Gotha Program", "between capitalist and communist society there lies the period of the revolutionary transformation of the one into the other. Corresponding to this is also a political transition period in which the state can be nothing but the revolutionary dictatorship of the proletariat."
In the 1920s and '30s, a group of dissident Marxists founded the Institute for Social Research in Germany, among them Max Horkheimer, Theodor Adorno, Erich Fromm, and Herbert Marcuse. As a group, these authors are often called the Frankfurt School. Their work is known as Critical Theory, a type of Marxist philosophy and cultural criticism heavily influenced by Hegel, Freud, Nietzsche, and Max Weber.The Frankfurt School broke with earlier Marxists, including Lenin and Bolshevism in several key ways. First, writing at the time of the ascendance of Stalinism and Fascism, they had grave doubts as to the traditional Marxist concept of proletarian class consciousness. Second, unlike earlier Marxists, especially Lenin, they rejected economic determinism. While highly influential, their work has been criticized by both orthodox Marxists and some Marxists involved in political practice for divorcing Marxist theory from practical struggle and turning Marxism into a purely academic enterprise.Other influential non-Bolshevik Marxists at that time include Georg Lukacs, Walter Benjamin and Antonio Gramsci, who along with the Frankfurt School are often known by the term Western Marxism. Henryk Grossman, who elaborated the mathematical basis of Marx's 'law of capitalist breakdown', was another affiliate of the Frankfurt School. Also prominent during this period was the Polish revolutionary Rosa Luxemburg.In 1949 Paul Sweezy and Leo Huberman founded Monthly Review, a journal and press, to provide an outlet for Marxist thought in the United States independent of the Communist Party.In 1978, G. A. Cohen attempted to defend Marx's thought as a coherent and scientific theory of history by reconstructing it through the lens of analytic philosophy. This gave birth to Analytical Marxism, an academic movement which also included Jon Elster, Adam Przeworski and John Roemer. Bertell Ollman is another Anglophone champion of Marx within the academy.
