Reality-Mode Ontology: A Multi-Scale, Multi-Modal Relational Framework of Universals and Particulars

This paper develops a unified metaphysical-cognitive framework that reconceives universals and particulars as scale-relative, contrast-generated, and mode-dependent structures. Against both nominalism and Platonism, I argue that particulars depend on universals for intelligibility, universals depend on particulars for recognition, and both depend on contrast relations. Universals emerge as structural invariants across contrastive clusters of particulars, and at higher scales they themselves function as particulars, generating an indefinitely nested ontology.

I introduce the novel concept of Reality-Mode Perception (RMP): the thesis that human cognition does not perceive objects as they exist across their full modal range, but only the mode of reality accessible through our sensory-cognitive apparatus. Redness, for example, is a mode-specific universal derived from our visual system, not the underlying wavelength structure; similarly, 'water' is a mode-unified universal compressing multiple physical states (ice, liquid, vapor). Integrating RMP with predictive processing (Friston, 2010; Clark, 2016), coarse-graining (Wimsatt, 2007), and categorization research (Rosch, 1978), I argue that the universal-particular binary is a genuine cognitive limitation arising from our restricted access to the modal structure of reality.

The result is a Reality-Mode Ontology: a relational, scale-relative, and mode-relative metaphysics that integrates phenomenology, analytic metaphysics, structural realism, and cognitive science into a coherent account of intelligibility.
