Aristotelian realism and the idea of tabula rasa associated with Marxist materialism are, at bottom, opposite positions.

Aristotelian realism

Aristotle’s realism means recognizing that there are objective laws in human action, in biology, and in economics that cannot be violated with impunity by political power.

Aristotle’s philosophy is deeply teleological (every action is oriented toward an end): it holds that nature does nothing in vain and that human beings possess a rational nature, an essence, and unalterable limits that cannot be bent to the will of whoever wants to change human nature.

For Aristotelian realism:

Reality exists independently of the desires, whims, decrees, or coercions of any ruler, legislator, or board of planners.
The essence of the human being has limits that must be respected; it says that human nature cannot be changed without problems arising.
Ignoring human nature and claiming to rewrite the laws of economic scarcity by decree inevitably leads to the failure of the system.
When a regime tries to subvert reality through top-down mandates, it collides with unbreakable limits, unleashing distortions, ruin, and institutional collapses.
From the point of view of Biology, claiming to redesign human behavior or suppress the natural incentives of survival through government decrees amounts to an adaptive disease that destroys the resilience of the species.

Connection with Classical Libertarianism

Although Aristotle lived in the 4th century B.C. —in an era without free-market capitalism or modern individual rights—, his philosophical realism constituted the conceptual foundation to which the builders of liberal thought resorted.

Austrian economists and theorists of liberty saw in this realism proof that life in society, private property, and the spontaneous order of the market are not arbitrary legislative inventions, but the only institutions compatible with the rational and free nature of the human being.

Summary

While collectivism falls into the idealist illusion that the State can rewrite society through force, philosophical realism starts from the sober acceptance that civilization only prospers when its norms are organized in strict harmony with the inescapable reality of the human being.

While Aristotelian realism affirms an objective human nature that the political and economic order must respect (an idea that connects with classical libertarianism and with Austrian methodology), Marxist materialism holds that this “nature” is largely a product of the relations of production and is therefore transformable.

This difference is decisive: if man has a real nature (rationality, intentional action, time preference, etc.), then there are objective limits to social engineering.

Relation between the two

Aspect	Aristotelian realism	Marxist materialism (and social tabula rasa)
Human nature	Fixed, essential, with ends	Historical, socially produced, plastic
Essences / universals	Real and immanent in things	Product of material and historical relations
Determination	Nature limits and orients	Material conditions determine and transform
Possibility of radical change	Limited by human essence	Practically unlimited through praxis and change of the material base
Knowledge	Abstraction of real forms	Determined by class position and praxis
