Psycho-logic: some thoughts and after-thoughts

The main features of the system of psycho-logic and its historical origins, especially in the writings of Heider and Piaget, are briefly reviewed. An updated version of the axioms of psycho-logic, and a list of the semantic primitives of Wierzbicka are presented. Some foundational questions are discussed, including the genetically determined limitations of human knowledge, the constructive, moral, and political nature of the approach, the role of fortuitous events, the ultimate limitations of psychological knowledge (the "balloon" to be inflated from the inside), the role of the subjective unconscious, and the implications of the approach for practice.
