The Initial Exposition by Young Engels on the Correlation between Thought and Existence

-- Grounded in a Critique of Schelling's Doctrine of Potenz

Abstract

This paper examines young Engels' critique of Schelling's “Doctrine of Potenz” as an entry point to elucidate the early formation of his materialist framework for the thought-existence relationship. In Schelling's positive philosophical system, Potency (Potenz) is posited as the universal essence of Being, claiming to reconcile existential tensions through the dialectical movement of the triadic potencies (A¹-A³ structure), which served as a critique of Hegel's pan-logicism. However, this theory is undermined by three ontological dilemmas: the rupture between reason and the “unprethinkable being”, the circularity inherent in the triadic structure, and the ambiguity surrounding temporal generation. Based on analysis of Schelling's Berlin lectures, Engels systematically refuted the transcendental grounding of potency, arguing that it merely constitutes an “abstract projection of reality”. He condemned Schelling's inversion of the reason-reality nexus, insisting that only potency capable of actualization into existence holds philosophical significance. By synthesizing Hegelian dialectics with Feuerbachian materialism, Engels formulated a dual ontological principle: first, reason must be grounded in natural existence; second, philosophy must originate from the “actuality of being”, rather than Schelling's “Potenz prior to Being”. This critique marked Engels' transition from speculative philosophy toward “general materialism”, laying theoretical foundations for the “primacy of practice” thesis in his historical materialism.
