I agree that the liberal state is a tool for class power and that formal equality is often just a mask for material exploitation.
When I say liberalism is the basis of Marx’s work, I am referring to its humanist core: the promise of individual autonomy and self-determination. With the exception of private property, the values you listed contain a seed of humanism that is currently restricted to a select few.
Nothing forces a value like autonomy to be contingent on private property. Marx shows that private property is exactly what prevents autonomy for the majority. By explaining why these values fail under capitalism, Marx is not dismissing them. He identifies the property relations that prevent human progress. He argues that to actually realize the individual rights liberalism promises, we must first abolish the class power used to protect them for the few.
Even more so, Marx took a core liberal value, the free development of the individual, and proved it is materially impossible to achieve under a system of private property. He analyzed liberalism by holding it to its own standards, showing that the very system it created could never fulfill the values it proclaimed. This is why I call it incomplete because it offers the legal form of freedom without the material content.
Marxism does not do away with the individual. It identifies the material conditions, the abolition of class, required for the individual to be truly autonomous. Marx does not throw away the promise of the Enlightenment. He offers the only material path to make it a reality for everyone.
P.S. I think treating liberal idealism and Marxist materialism as mutually exclusive is a bit non-dialectical. Liberalism was a material response to feudalism, not just a daydream. Likewise, Marx did not start from zero with a cold science of factories. He took the enlightenment goal of human dignity and used a materialist method to discover why that goal was being strangled. To Marx, ideas are themselves a material force once they have gripped the masses and formed a collective consciousness. To suggest Marx had no guiding ideas is just as one-sided as suggesting that liberal thinkers were fully divorced from the material world.







I agree that liberalism has historically functioned as a facade for domination. But just as chemistry emerged from the quest of alchemy, Marxism identifies the germ of humanism within the chaff of the liberal state. I am not suggesting we complete liberalism, but that we realize its hollowed-out promises by stripping away its class-bound distortions. Just as liberalism sublated feudal honor into human dignity of the citizen, Marxism sublates the abstract citizen into the social individual. What is preserved isn’t always the core of the historical era, but what allows for the continual, universal, and material emancipation in ever widening circles from the political to the human. The extension of emancipation to all is his normative anchor.
Regarding the individual: simply inverting the liberal structure and placing the collective conditions where the individual used to be is a mechanical negation, not a dialectical synthesis. If the individual is merely subordinate to the collective conditions, alienation remains.
You cannot transform collective conditions without the development of individual class consciousness. These two are in a bidirectional, internal relationship. They sublate one another. The result is an association of free individuals who are conscious of their social nature, not cogs in a machine.
You say that Marx’s guiding ideas were Hegelian, not liberal. But Hegel was the philosopher of the modern liberal subject. He didn’t seek to abolish the individual in favor of the collective; he sought to move the individual from an abstract freedom (the right to be left alone) to a concrete freedom (the power to act in a rational society). Marx is working within the tradition of human emancipation. He isn’t trying to subordinate the person to the collective; he is using Hegelian logic to find a material way to actually achieve the individual autonomy that Liberalism promised but could never deliver.
I am at peace with leaving the argument here: for Marx, the collective is the means, but the ‘complete return of man to himself’ is the end. To lose sight of that human end is to lose the very essence of the critique.
