Abstract Thought and the Shape of a Life: A Dual-Pathway Model of Regulatory and Intrinsic Abstraction

Philosophical judgments of abstract thought are caught in an antinomy. One tradition, running from critical theory to the critique of instrumental reason, treats sustained abstraction as estrangement from concrete life. Another tradition, running from Platonic and Husserlian idealization to the self-understanding of working mathematicians, treats abstraction as the route to impersonal truth and aesthetic order. This paper argues that the antinomy rests on a category error. Both sides evaluate abstract thinking as such, whereas the proper object of evaluation is the existential function that an abstract activity serves within a particular life. The same abstract activity, it is argued, can stand in two functional relations to the self and the lifeworld. Regulatory abstraction is a compensatory organizing structure that gains intensity when the concreteness of a life is weak. Intrinsic abstraction is the expression of a comparatively stable aesthetic-cognitive affinity whose satisfaction conditions are internal to the activity and which is therefore largely insensitive to fluctuations in life concreteness. The paper offers a conceptual analysis of life concreteness along four structural dimensions, specifies the mechanisms through which abstract systems compensate for deficits in each dimension, and individuates the two functional relations by their counterfactual dependence on life concreteness rather than by introspective labels. A state-by-trait interaction model is proposed in which a state variable of life concreteness and a stable parameter of intrinsic abstract affinity jointly predict abstract engagement, producing falsifiable longitudinal and experience-sampling predictions. The model dissolves the philosophical antinomy without relativism, reframes the critique of alienation as a critique of monopolization rather than of abstraction, and provides a naturalistic account of the intrinsic appeal of abstract thought that does not require Platonist metaphysics.
