Final answer:
Karl Marx is the philosopher who analyzed society as being fundamentally divided between two classes, the bourgeoisie and the proletariat, which clashed in the capitalist system, leading to conflict and change.
Step-by-step explanation:
The individual you are referring to is Karl Marx, a German philosopher and economist known for his critical analysis of capitalism. Marx pioneered the Conflict Theory, which posits that social structures are defined by ongoing class struggles. He identified the factory as the central place where this conflict played out between two main classes: the bourgeoisie, who owned the means of production, and the proletariat, who were the laborers and sold their labor for wages.
According to Marx, the industrial capitalists known as the bourgeoisie unfairly exploited the working class, or proletariat, leading to deep social inequalities. He believed that these class conflicts drove societal change and would inevitably lead to a proletarian revolution, overthrowing the existing capitalist order and eventually establishing a society without class divisions—a socialist utopia.
