The Theses on Feuerbach: Critique or Continuation of the Dialectic?
This text is a preview of History of the Reception of Hegel, volume I, to be published in 2026 by Reflexivity Press.
In the spring of 1845, Marx jotted down eleven brief theses on Ludwig Feuerbach in a notebook in Brussels. Only forty years later, in 1888, did Engels publish these notes as the “Theses on Feuerbach.” They became one of the most-quoted texts in the history of philosophy — and at the same time one of the most frequently misunderstood.
The eleventh thesis is famous: “The philosophers have only interpreted the world in various ways; the point is to change it.” This formulation is usually read as a break with all previous philosophy, as a rejection of theory in favor of practice. But is that really what is meant? Or is this thesis itself an interpretation — a theoretical statement about the relationship between theory and practice?
The first thesis is systematically more decisive: “The chief defect of all hitherto existing materialism (that of Feuerbach included) is that the thing, reality, sensuousness, is conceived only in the form of the object or of contemplation, but not as sensuous human activity, practice, not subjectively.”[1]
This formulation is remarkable — for here Marx speaks in genuinely Hegelian terms. The critique of the “form of the object” points to a precise systematic location in Hegel’s Logic: the transition from the section on “Objectivity” to the “Idea” in the Doctrine of the Concept. Marx seems to be quoting Hegel almost verbatim here.
In Hegel, the doctrine of the concept passes through three great movements: the subjective concept (the forms of thought), objectivity (the world as an ordered whole), and the idea (the living unity of both). In the section on “Objectivity,” Hegel treats mechanism, chemism, and teleology — the world as an object that follows external laws. But this “form of the object” proves incomplete: it presupposes a thinking subject that first constitutes this objectivity.
The transition to the idea accomplishes exactly the movement that Marx demands here. The idea is no longer “object” in the sense of a finished thing of contemplation, but a living process of the reciprocal interpenetration of subject and object. Hegel develops three stages: the idea of life (unconscious self-organization), the idea of cognition (theoretical appropriation of the world), and the idea of the will (practical transformation of the world).
This is precisely Marx’s point: “sensuous human activity” is the unity of cognition and will — not first contemplative observation and then external action, but both as moments of a unified practical accomplishment. What Hegel develops abstractly as the “idea of cognition and will,” Marx concretizes as social practice. Human beings do not change the world according to finished plans derived from pure thought, but in the exercise of a practice that originally unites cognition and transformation.
The eleventh thesis — “The philosophers have only interpreted the world in various ways; the point is to change it” — is, from this perspective, not a rejection of theory but a demand for the practical idea. It carries out the transition from the idea of cognition (contemplative philosophy) to the idea of the will (revolutionary practice). But this transition is itself systematically laid out in Hegel — in the doctrine of the concept as the development from theoretical to practical cognition, in the philosophy of right as the transition from abstract right to concrete ethical life.
The “form of the object or of contemplation” is thus Hegel’s objectivity without the idea — the world as already finished, needing only to be recognized. Marx’s “sensuous human activity” is Hegel’s idea of cognition and will — the world as a process constituted and transformed through human practice. The terminology differs; the systematic structure is the same.
The Phenomenology of Spirit develops consciousness precisely not as a passive mirror of reality but as its active production. Spirit, in Hegel, is not contemplative but productive. What Marx criticizes is not Hegel but Feuerbach — and precisely because Feuerbach falls behind Hegel, back to a precritical theory of contemplation. Feuerbach had wanted to replace Hegel’s thinking of mediation with a philosophy of immediate intuition — a regression behind critical philosophy.
The third thesis states the problem more sharply: “The materialist doctrine concerning the changing of circumstances and upbringing forgets that circumstances are changed by men and that the educator must himself be educated. This doctrine must, therefore, divide society into two parts, one of which is superior to society. The coincidence of the changing of circumstances and of human activity or self-changing can be conceived and rationally understood only as revolutionary practice.”[2]
This formulation is more Hegelian than Hegel himself. The “coincidence” of objective change and subjective self-change is nothing other than the structure of reciprocal action [Wechselwirkung] as Hegel develops it in the Logic of Essence. Both sides constitute one another — there is no one-sided relation of determination. “Revolutionary practice” is the conscious appropriation of this reciprocal action.
What Marx accomplishes here is not the overcoming of dialectic but its concretization. He shows that the abstract structure of reciprocal action is really at work in social practice. “Sensuous human activity” is the exercise of action that originally unites subject and object, theory and practice.
