Karl Marx (Leaving Cert Politics and Society): Revision Notes
Karl Marx
Introduction and background
Karl Marx (1818-1883) was a German philosopher, economist and political theorist who became one of the most influential thinkers in modern history. His ideas have shaped revolutions around the world and influenced countless political movements. Marx lived during the industrial age, witnessing both the remarkable technological progress and the severe social problems of 19th-century capitalism.

Marx lived through a period of rapid industrialisation in Europe, where he witnessed firsthand the transformation of traditional societies into modern capitalist economies. This historical context was crucial in shaping his revolutionary ideas about economic and social systems.
Marx famously wrote: "The philosophers have only interpreted the world, in various ways. The point, however, is to change it." This quote captures his belief that theory should lead to practical action and social transformation.
Marx's critique of capitalist society
Marx acknowledged the impressive achievements of the capitalist age, recognising how it had "accomplished wonders... drawn all nations into civilisation... created enormous cities... witnessed the subjection of nature's forces to man, the development of new machinery, the application of chemistry to industry and agriculture, steam-navigation, railways, electric telegraphs, the clearing of whole continents for cultivation, canalisation of rivers..."
However, Marx argued that capitalism came at a terrible human cost. He believed that capitalist society had left "no other bond between man and man but naked self-interest... callous cash payment... It has dissolved personal dignity into exchange value... torn off the veil of feeling and affection from family relationships and reduced them to purely financial connections."
Marx's critique wasn't simply about economics - he argued that capitalism fundamentally altered human relationships, reducing all social connections to monetary transactions and destroying traditional bonds of community and family.
Marx's main works, Das Capital and The Communist Manifesto, present his philosophy of history and his theory about how society could be transformed.
Dialectical materialism: Historical and social development
Marx developed a theory called dialectical materialism, which argues that economic conditions determine all historical events. According to Marx, "Man must eat to live" - this means that the survival of humanity depends on successfully producing what people need from nature.
Production is therefore the most important human activity. How society organises the production and distribution of necessities forms the economic base, which shapes all other aspects of life including politics, culture and ideas.
Think of dialectical materialism as Marx's explanation for why history unfolds the way it does. Unlike philosophers who focused on ideas driving change, Marx argued that material conditions - how people produce and distribute goods - are the real driving forces behind historical development.
Marx argued: "It is not the consciousness of men that determines their existence, but, on the contrary, their social existence determines their consciousness." This means that people's position within the economic system shapes how they think and see the world.
Historical change and class conflict
For Marx, history is fundamentally the story of class conflict and struggle. He wrote: "The history of all hitherto existing societies is the history of class struggles. 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."
Marx saw this conflict as an inevitable law of history. Every society that fails to adequately meet everyone's needs contains the seeds of its own destruction. Historical progress results from the interaction between competing forces, with each conflict leading to a higher stage of development.
Marx viewed class conflict not as an unfortunate side effect of society, but as the primary mechanism that drives all historical change. Understanding this concept is essential to grasping his entire worldview.
Class conflict: Bourgeoisie vs proletariat
Marx identified two main classes in capitalist society: the bourgeoisie and the proletariat.
- The bourgeoisie own the means of production (factories, land, machinery)
- The proletariat are the working class who must sell their labour to survive
Marx described the proletariat as "wage slaves" because they are systematically exploited by the capitalist class. Economic exploitation occurs because capitalists extract surplus value from workers - essentially paying workers less than the value they create through their labour.
Worked Example: Understanding Surplus Value
Imagine a worker in a shoe factory who produces 10 pairs of shoes in a day. Each pair sells for 1,000 in value. However, the worker is only paid 920 (minus materials and overhead costs) becomes surplus value that the capitalist owner keeps as profit. Marx argued this difference represents the exploitation of the worker's labour.
This exploitation alienates workers from their true nature and abilities. Alienation means that capitalism separates workers from the production process, the objects they produce, and their ability to develop their skills and talents. Workers don't produce what they need, but rather commodities to be sold for profit.
The path to revolution
Marx believed capitalism was inherently unstable and contained the seeds of its own destruction. As economic power becomes concentrated in fewer hands and the impoverishment of the majority continues, a workers' revolution would become inevitable.
Marx's message was essentially a revolutionary call to action: "The workers have nothing to lose but their chains. They have a world to win. Workers of the world, unite!"
The state, according to Marx, serves as an instrument of oppression that protects the interests of the dominant economic class. To defeat capitalism, the state machine must be overthrown.
Marx believed that revolution was not just desirable but inevitable. He saw the internal contradictions of capitalism - growing wealth inequality and worker exploitation - as forces that would naturally lead to the system's collapse.
Communist society
Marx envisioned a communist society organised around human needs rather than profit. In this classless society, goods would be distributed according to the principle: "from each according to his ability, to each according to his need."
With the abolition of the class system, there would no longer be a need for the state as an instrument of class oppression. Marx believed this would allow humanity to realise its full potential.
Marx's vision of communism wasn't about government control of everything, but rather about eliminating class divisions entirely. He believed that without classes, there would be no need for a state to enforce the dominance of one class over another.
Marx's influence
Marx's political philosophy has had enormous influence, particularly his analysis of capitalism and economic power in social relationships. Before Marx, most economists assumed capitalism was natural and inevitable. Marx challenged this view, arguing that capitalism was historically specific and destined to be replaced.
Marx highlighted how ideology maintains power structures. He argued that the ideas of the ruling class become the dominant ideas in society. This leads to false consciousness, where people accept values and beliefs that aren't really in their own interests, such as supporting economic systems that primarily benefit the wealthy.
The concept of false consciousness helps explain why people sometimes support systems that work against their own interests. Marx argued that dominant ideologies shape how we understand the world, often preventing us from seeing alternatives to the current system.
