Socrates favoured truth as the highest value, proposing that it could be discovered through reason and logic in discussion: ergo, dialectic. Socrates valued rationality (appealing to logic, not emotion) as the proper means for persuasion, the discovery of truth, and the determinant for one's actions.
Different forms of dialectical reasoning have emerged throughout history from the Indosphere (Greater India) and the West (Europe). These forms include the Socratic method, Hindu, Buddhist, Medieval, Hegelian dialectics, Marxist, Talmudic, and Neo-orthodoxy..
Influences on Karl Marx are generally thought to have been derived from three sources: German idealist philosophy, French socialism, and English and Scottish political economy
Immanuel Kant is believed to have had the greatest influence of any philosopher of modern times. Kantian philosophy was the basis on which the structure of Marxism was built — particularly as it was developed by Hegel. Hegel's dialectical method, which was taken up by Karl Marx, was an extension of the method of reasoning by “antinomies” that Kant used.
Hegelians were of 2 grs.
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, Friedrich Engels, and Marx.[2] They were often referred to as the Young Hegelians.
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:
In the social production of their existence, men inevitably enter into definite relations, which are independent of their will, namely relations of production appropriate to a given stage in the development of their material forces of production. The totality of these relations of production constitutes the economic structure of society, the real foundation, on which arises a legal and political superstructure and to which correspond definite forms of social consciousness. The mode of production of material life conditions the general process of social, political and intellectual life. It is not the consciousness of men that determines their existence, but their social existence that determines their consciousness.
Marx (and Engels) saw in Feuerbach's emphasis on people and human needs a movement toward a materialistic interpretation of society.
Ludwig Feuerbach was a German philosopher and anthropologist. Feuerbach proposed that people should interpret social and political thought as their foundation 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) saw in Feuerbach's emphasis on people and human needs a movement toward a materialistic interpretation of society. [3] 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 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 (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.
Also, in his Theses on Feuerbach (1844), he writes that "the philosophers have only interpreted the world, in various ways, the point is to change it". This opposition between, firstly, various subjective interpretations given by philosophers, which may be, in a sense, compared with Weltanschauung designed to legitimize the current state of affairs, and, secondly, the effective transformation of the world through praxis, which combines theory and practice in a materialist way, is what distinguishes "Marxist philosophers" from the rest of philosophers. Indeed, Marx's break with German Idealism involves a new definition of philosophy; Louis Althusser, founder of "Structural Marxism" in the 1960s, would define it as "class struggle in theory". Marx's movement away from university philosophy and towards the workers' movement is thus inextricably linked to his rupture with his earlier writings, which pushed Marxist commentators to speak of a "young Marx" and a "mature Marx", although the nature of this cut poses problems. A year before the Revolutions of 1848, Marx and Engels thus wrote The Communist Manifesto, which was prepared to an imminent revolution, and ended with the famous cry: "Proletarians of all countries, unite!". However, Marx's thought changed again following Louis-Napoleon Bonaparte's December 2, 1851 coup, which put an end to the French Second Republic and created the Second Empire which would last until the 1870 Franco-Prussian War. Marx thereby modified his theory of alienation exposed in the Economic and Philosophical Manuscripts of 1844 and would latter arrive to his theory of commodity fetishism, exposed in the first chapter of the first book of Das Kapital (1867). This abandonment of the early theory of alienation would be amply discussed, several Marxist theorists, including Marxist humanists such as the Praxis School, would return to it. Others, such as Althusser, would claim that the "epistemological break" between the "young Marx" and the "mature Marx" was such that no comparisons could be done between both works, marking a shift to a "scientific theory" of society.
