Objective foundations for the study of mental qualities
PsyArXiv Preprints June 15, 2025 David Rosenthal 1 citation
Quality spaces can objectively represent mental qualities by grounding them in perceptual discrimination rather than subjective introspection. Mental qualities have a robust connection to how organisms perceptually discriminate stimuli, allowing quality spaces to be constructed without relying on impressionistic subjective access. Subjective appearances of mental qualities are constitutively tied to perceptual roles, as each appearance consists in how it seems when perceiving a specific object type. Therefore, quality spaces based on perceptual role can also characterize subjective appearances, though the tie to perceptual role is more fundamental. These spaces primarily represent discriminable stimuli objectively, and secondarily represent corresponding mental qualities in terms of both perceptual roles and subjective appearances.
