Piaget’s account of sensorimotor intelligence motivates the distinction among assimilation, accommodation, and equilibration [ Piaget , 1952 ] . Spelke’s core-knowledge program supplies the fragment-specific developmental constraints and the challenge of later composition [ Spelke , 2022 , 2023 ] . The hypothesis-fibration and 3. Later parts develop homotopy, tangent, safety, and transport doctrines for the repair obligations exposed by this developmental model.

Moro’s impossible languages illustrate a domain in which biological admissibility is proposed to define a proper subclass of formal structures [ Moro , 2023 ] . The Transformer architecture was introduced by Vaswani et al. [ 2017 ] . The systematic-generalization results of Lake and Baroni [ 2018 , 2023 ] caution against both identifying benchmark composition with world identification and declaring neural architectures incapable of systematicity. Current agent time-horizon measurements and coding-evaluation audits illustrate both the extraordinary rate of capability improvement and the fragility of the tests used to describe it [ METR , 2026 , OpenAI , 2026b ] . The JEPA program provides a complementary account of abstraction through prediction in learned representation spaces [ LeCun , 2022 , Assran et al. , 2023 , Assran et al. , 2025 ] . Mac Lane’s treatment of Kan extensions supplies the classical universality claim; the distinction developed here is between that expressive universality and identification from a presentation [ Mac Lane , 1971 ] .
