Proposal for an optical simile that assimilates the cognitive faculties of classical epistemology (sensibility and understanding) to a spherical refractive diopter (psychic diopter), tracing over it the basic divergences of two approaches, realistic and phenomenal. The simile will also allow us to justify the decline of Metaphysics, the revocation of the epistemological statute of abstract knowledge about ens in quantum ens by Transcendental Idealism due to a congenital not-emmetropia of a defective intellect (ammetropic noûs: genetic refraction error respect to the remote object) to which only the dialectical evasion to the noumenon (itselfness as an asymptotic rational -non ontological- tessitura of being: noumenal entity, independent of empirical observation, denied cognition of things in themselves). Consequent to the epistemological eviction of Metaphysics will be the phenomenalization of eîdos, a monofacial lógos bare path in his phenomenological assault on reality.
