Influences on Karl Marx
Encyclopedia
Influences on Karl Marx are commonly referred to as deriving from three sources: German idealist philosophy, French socialism, and English & Scottish political economy. Although this "three sources" model is an oversimplification, it still has some measure of truth.

, by the time of his death, was the most prominent philosopher in Germany. His views were widely taught, and his students were highly regarded. His followers soon divided into right-wing and left-wing Hegelians. Theologically and politically the right-wing Hegelians offered a conservative interpretation of his work. They emphasized the compatibility between Hegel's philosophy and Christianity. Politically, they were orthodox. The left-wing Hegelians eventually moved to an atheistic position. In politics, many of them became revolutionaries. This historically important left-wing group included Ludwig Feuerbach, Bruno Bauer

Marx's view of history, which came to be called historical materialism
Historical materialism
Historical materialism is a methodological approach to the study of society, economics, and history, first articulated by Karl Marx as "the materialist conception of history". Historical materialism looks for the causes of developments and changes in human society in the means by which humans...

, 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 slavery 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 summarized the materialistic aspect of his theory of history in the 1859 preface to A Contribution to the Critique of Political Economy
A Contribution to the Critique of Political Economy

The book is mainly an analysis of capitalism, achieved by critiquing the writings of the leading theoretical exponents of capitalism at that time: these were the political economists, nowadays often...

. This notion is often understood as a simple historical narrative: primitive communism had developed into slave states. Slave states had developed into feudal societies. Those societies in turn became capitalist states, and those states would be overthrown by the self-conscious portion of their working-class, or proletariat, creating the conditions for socialism and, ultimately, a higher form of communism than that with which the whole process began. Marx illustrated his ideas most prominently by the development of capitalism from feudalism

Ludwig Feuerbach

Ludwig Feuerbach was a German philosopher and anthropologist. According to Feuerbach, social and political thought should take as their foundation people and their material needs. He held that an individual is the product of their environment, that the whole consciousness of a person is the result of the interaction of sensory organs and the external world. Marx (and Engels
Friedrich Engels
Friedrich Engels was a German industrialist, social scientist, author, political theorist, philosopher, and father of Marxist theory, alongside Karl Marx. In 1845 he published The Condition of the Working Class in England, based on personal observations and research...

) saw in Feuerbach's emphasis on people and human needs a movement toward a materialistic interpretation of society.


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. However 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 ideology prevented people from seeing the material conditions of their lives clearly.

What distinguished Marx from Feuerbach was his view of Feuerbach's humanism
Humanism
Humanism is an approach in study, philosophy, world view or practice that focuses on human values and concerns. In philosophy and social science, humanism is a perspective which affirms some notion of human nature, and is contrasted with anti-humanism....

 as excessively abstract, and so no less ahistorical and idealist than what it purported to replace, namely the reified notion of God found in institutional Christianity that legitimized the repressive power of the Prussian state. Instead, Marx aspired to give ontological priority to what he called the "real life process" of real human beings, as he and Engels said in The German Ideology
The German Ideology
The German Ideology is a book written by Karl Marx and Friedrich Engels around April or early May 1846. Marx and Engels did not find a publisher. However, the work was later retrieved and published for the first time in 1932 by David Riazanov through the Marx-Engels Institute in Moscow...

(1846):

In direct contrast to German philosophy, which descends from heaven to earth, here we ascend from earth to heaven. That is to say, we do not set out from what men say, imagine, conceive, nor from men as narrated, thought of, imagined, conceived, in order to arrive at men in the flesh. We set out from real, active men, and on the basis of their real life process we demonstrate the development of the ideological reflexes and echoes of this life process. The phantoms formed in the human brain are also, necessarily, sublimates of their material life process, which is empirically verifiable and bound to material premises. Morality, religion, metaphysics, all the rest of ideology and their corresponding forms of consciousness, thus no longer retain the semblance of independence. They have no history, no development; but men, developing their material production and their material intercourse, alter, along with this, their real existence, their thinking, and the products of their thinking. Life is not determined by consciousness, but consciousness by life.

(1844), he writes that "the philosophers have only described the world, in various ways, the point is to change it".

Marx's early writings are thus a response towards Hegel, German Idealism and a break with the rest of the Young Hegelians.

Marx critiqued Smith and Ricardo for not realizing that their economic concepts reflected specifically capitalist institutions, not innate natural properties of human society, and could not be applied unchanged to all societies. He proposed a systematic correlation between labour-values and money prices. He claimed that the source of profits under capitalism is value added by workers not paid out in wages. This mechanism operated through the distinction between "labour power", which workers freely exchanged for their wages, and "labour", over which asset-holding capitalists thereby gained control.

This practical and theoretical distinction was Marx's primary insight, and allowed him to develop the concept of "surplus value", which distinguished his works from that of Adam Smith

Charles Fourier and Henri de Saint-Simon

In 1833 France was experiencing a number of social problems arising out of the Industrial Revolution. A number of sweeping plans of reform were developed by thinkers on the left. Among the more grandiose were the plans of Charles Fourier

. Fourier wanted to replace modern cities with utopian communities, while the Saint-Simonians advocated directing the economy by manipulating credit. Although these programs didn’t have much support, they did expand the political and social imagination of their contemporaries, including Marx.

 participated in the February 1848 uprising and the composition of what he termed "the first republican proclamation" of the new republic. But he had misgivings about the new government because it was pursuing political reform at the expense of the socio-economic reform, which Proudhon considered basic. Proudhon published his own perspective for reform, Solution du problème social, in which he laid out a program of mutual financial cooperation among workers. He believed this would transfer control of economic relations from capitalists and financiers to workers. It was Proudhon's book What is Property?

In one of his first works, The Holy Family, Marx said, "Not only does Proudhon write in the interest of the proletarians, he is himself a proletarian, an ouvrier. His work is a scientific manifesto of the French proletariat." Marx, however, disagreed with Proudhon's anarchism and later published vicious criticisms of Proudhon. Marx wrote The Poverty of Philosophy

 was also influenced by 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. Thereafter Engels and Marx worked together for the rest of Marx's life, so that the collected works of Marx and Engels are generally published together, almost as if the output of one person. Important publications, such as the German Ideology and the Communist Manifesto, were joint efforts. Engels says "I cannot deny that both before and during my 40 years’ collaboration with Marx I had a certain independent share in laying the foundation of the theory, and more particularly in its elaboration." But he adds

In the first stage (called the Age of the Gods) religion, the family, and other basic institutions emerge; in the succeeding Age of Heroes, the common people are kept in subjection by a dominant class of nobles; in the final stage (the Age of Men) the people rebel and win equality, but in the process society begins to disintegrate. The connection between Vico's theory of history, and Marx's account of the evolution of society is apparent.

Charles Darwin

and recognized its value in supporting his theory of class struggle. He sent Darwin a personally inscribed copy of Das Kapital

Marx understood that Darwin's work both helped to explain the internal struggles of human society, and provided a material explanation for the processes of nature. In 1861, Karl Marx wrote to his friend Ferdinand Lassalle

, "Darwin’s work is most important and suits my purpose in that it provides a basis in natural science for the historical class struggle. ... Despite all shortcomings, it is here that, for the first time, ‘teleology’ in natural science is not only dealt a mortal blow but its rational meaning is empirically explained."

Having read Darwin's work and mentioned Darwin by name in Das Kapital
, it is presumable that Marx may have been influenced to some degree by Darwin.

Exaggeration of Darwin's Influence

However, the depth of the influence, if any, would certainly seem to be greatly exaggerated by a number
of religious fundamentalists who seek to paint Darwin's ideas as incredibly dangerous. There is no
mention of Darwin or evolution in The Communist Manifesto

Despite this, in The Disasters Darwinism Brought to Humanity, Harun Yahya (a Muslim creationist) writes: "Karl Marx, the founder of Communism, adapted Darwin's ideas, which deeply influenced him, to the dialectic process of history." Yahya also writes: "Marx revealed his sympathy for Darwin by dedicating his most important work, Das Kapital, to him."

This last bit is a common misconception that arose from a letter from Darwin to Edward Aveling

. The letter was published in 1931 in the Russian Communist
magazine, Under the Banner of Marxism, which went on to suggest that the enclosures referred to in the
letter might have been chapters from Das Kapital that dealt with evolution. It was not until 1975
that Aveling's letter to Darwin was discovered, debunking this myth.
