The third law, "negation of the negation", originated with Hegel. Although Hegel coined the term "negation of the negation", it gained its fame from Marx's using it in Capital . There Marx wrote this: "The [death] knell of capitalist private property sounds. The expropriators [capitalists] are expropriated. The capitalist mode of appropriation, the result of the capitalist mode of production, produces capitalist private property. This is the first negation [antithesis] of individual private property. [The "first negation", or antithesis, negates the thesis, which in this instance is feudalism, the economic system that preceded capitalism.] ... But capitalist production begets, with the inexorability of a law of Nature, its own negation. It [final communism, the synthesis] is the negation of [the] negation."
