Karl Marx was a German-born philosopher, economist, political theorist, historian, sociologist, journalist, and revolutionary socialist. His best-known works are the 1848 pamphlet The Communist Manifesto and the three-volume Das Kapital (1867–1894); the latter employs his theory of historical materialism in an analysis of capitalism, representing his greatest intellectual achievement. Marx's ideas and theories and their subsequent development, collectively known as Marxism, have exerted enormous influence on modern intellectual, economic, and political history.
Eduard Bernstein was a German social democratic Marxist theorist and politician. A member of the Social Democratic Party of Germany (SPD), Bernstein had held close association to Karl Marx and Friedrich Engels, but he began to identify what he believed to be errors in Marxist thinking and began to criticize views held by Marxism when he investigated and challenged the Marxist materialist theory of history. He rejected significant parts of Marxist theory that were based upon Hegelian metaphysics and rejected the Hegelian perspective of an immanent economic necessity to socialism.
Social Reform or Revolution? is an 1899 pamphlet by Polish-German Marxist theorist Rosa Luxemburg. Luxemburg argues that trade unions, reformist political parties and the expansion of social democracy—while important to the proletariat's development of class consciousness—cannot create a socialist society as Eduard Bernstein, among others, argued. Instead, she argues from a historical materialist perspective that capitalism is economically unsustainable and will eventually collapse and that a revolution is necessary to transform capitalism into socialism. The pamphlet was heavily influential in revolutionary socialist circles and along with Luxemburg's other work an important precursor to left communist theory.
The Social Democratic Workers' Party of Germany was a Marxist socialist political party in the North German Confederation during unification.
The Erfurt Program was adopted by the Social Democratic Party of Germany during the SPD Congress at Erfurt in 1891. Formulated under the political guidance of Eduard Bernstein, August Bebel, and Karl Kautsky, it superseded the earlier Gotha Program.
Marxism is a method of socioeconomic analysis that uses a materialist interpretation of historical development, better known as historical materialism, to understand class relations and social conflict and a dialectical perspective to view social transformation. It originates from the works of 19th-century German philosophers Karl Marx and Friedrich Engels. As Marxism has developed over time into various branches and schools of thought, no single, definitive Marxist theory exists. Marxism has had a profound impact in shaping the modern world, with various left-wing and far-left political movements taking inspiration from it in varying local contexts.
"From each according to his ability, to each according to his needs" is a slogan popularised by Karl Marx in his 1875 Critique of the Gotha Programme. The principle refers to free access to and distribution of goods, capital and services. In the Marxist view, such an arrangement will be made possible by the abundance of goods and services that a developed communist system will be capable to produce; the idea is that, with the full development of socialism and unfettered productive forces, there will be enough to satisfy everyone's needs.
In Marxist theory, a new democratic society will arise through the organised actions of an international working class, enfranchising the entire population and freeing up humans to act without being bound by the labour market. There would be little, if any, need for a state, the goal of which was to enforce the alienation of labor. Karl Marx and Friedrich Engels stated in The Communist Manifesto and later works that "the first step in the revolution by the working class, is to raise the proletariat to the position of ruling class, to win the battle for democracy" and universal suffrage, being "one of the first and most important tasks of the militant proletariat". As Marx 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". He allowed for the possibility of peaceful transition in some countries with strong democratic institutional structures, but suggested that in other countries in which workers can not "attain their goal by peaceful means" the "lever of our revolution must be force", stating that the working people had the right to revolt if they were denied political expression. In response to the question "What will be the course of this revolution?" in Principles of Communism, Friedrich Engels wrote:
Above all, it will establish a democratic constitution, and through this, the direct or indirect dominance of the proletariat.
Critique of political economy or simply the first critique of economy is a form of social critique that rejects the conventional ways of distributing resources. The critique also rejects what its advocates believe are unrealistic axioms, faulty historical assumptions, and taking conventional economic mechanisms as a given or as transhistorical. The critique asserts the conventional economy is merely one of many types of historically specific ways to distribute resources, which emerged along with modernity.
In Marxist thought, a communist society or the communist system is the type of society and economic system postulated to emerge from technological advances in the productive forces, representing the ultimate goal of the political ideology of communism. A communist society is characterized by common ownership of the means of production with free access to the articles of consumption and is classless, stateless, and moneyless, implying the end of the exploitation of labour.
The Critique of the Gotha Programme is a document based on a letter by Karl Marx written in early May 1875 to the Social Democratic Workers' Party of Germany (SDAP), with whom Marx and Friedrich Engels were in close association.
The socialist mode of production, sometimes referred to as the communist mode of production, or simply (Marxian) socialism or communism as Karl Marx and Friedrich Engels used the terms communism and socialism interchangeably, is a specific historical phase of economic development and its corresponding set of social relations that emerge from capitalism in the schema of historical materialism within Marxist theory. The Marxist definition of socialism is that of production for use-value, therefore the law of value no longer directs economic activity. Marxist production for use is coordinated through conscious economic planning. According to Marx, distribution of products is based on the principle of "to each according to his needs"; Soviet models often distributed products based on the principle of "to each according to his contribution". The social relations of socialism are characterized by the proletariat effectively controlling the means of production, either through cooperative enterprises or by public ownership or private artisanal tools and self-management. Surplus value goes to the working class and hence society as a whole.
Revolutionary socialism is a political philosophy, doctrine, and tradition within socialism that stresses the idea that a social revolution is necessary to bring about structural changes in society. More specifically, it is the view that revolution is a necessary precondition for transitioning from a capitalist to a socialist mode of production. Revolution is not necessarily defined as a violent insurrection; it is defined as a seizure of political power by mass movements of the working class so that the state is directly controlled or abolished by the working class as opposed to the capitalist class and its interests.
In Marxist philosophy, the dictatorship of the proletariat is a condition in which the proletariat holds state power. The dictatorship of the proletariat is the intermediate stage between a capitalist economy and a communist economy, whereby the post-revolutionary state seizes the means of production, compels the implementation of direct elections on behalf of and within the confines of the ruling proletarian state party, and institutes elected delegates into representative workers' councils that nationalise ownership of the means of production from private to collective ownership. During this phase, the administrative organizational structure of the party is to be largely determined by the need for it to govern firmly and wield state power to prevent counterrevolution and to facilitate the transition to a lasting communist society.
The proletariat is the social class of wage-earners, those members of a society whose only possession of significant economic value is their labour power. A member of such a class is a proletarian or a proletaire. Marxist philosophy regards the proletariat under conditions of capitalism as an exploited class - forced to accept meager wages in return for operating the means of production, which belong to the class of business owners, the bourgeoisie.
Orthodox Marxism is the body of Marxist thought which emerged after the death of Karl Marx and Friedrich Engels in the late 19th century, expressed in its primary form by Karl Kautsky. Kautsky's views of Marxism dominated the European Marxist movement for two decades, and orthodox Marxism was the official philosophy of the majority of the socialist movement as represented in the Second International until the First World War in 1914, whose outbreak caused Kautsky's influence to wane and brought to prominence the orthodoxy of Vladimir Lenin. Orthodox Marxism aimed to simplify, codify and systematize Marxist method and theory by clarifying perceived ambiguities and contradictions in classical Marxism.
Karl Johann Kautsky was a Czech-Austrian philosopher, journalist, and Marxist theorist. A leading theorist of the Social Democratic Party of Germany (SPD) and the Second International, Kautsky advocated orthodox Marxism, which emphasized the scientific, materialist, and determinist character of Karl Marx's work. This interpretation dominated European Marxism for two decades, from the death of Friedrich Engels in 1895 to the outbreak of World War I in 1914.
"To each according to his contribution" is a principle of distribution considered to be one of the defining features of socialism. It refers to an arrangement whereby individual compensation is representative of one's contribution to the social product in terms of effort, labor and productivity. This is in contrast to the method of distribution and compensation in capitalism, an economic and political system in which property owners can receive income by virtue of ownership irrespective of their contribution to the social product.
Historical materialism is Karl Marx's theory of history. Marx locates historical change in the rise of class societies and the way humans labor together to make their livelihoods.
