The General Genetic Law of Cultural Development
Vygotsky's foundational claim that every higher psychological function appears first on the social plane, between people, and only afterward on the individual plane, within the person — inverting the Western assumption that cognition originates inside the skull.
The general genetic law of cultural development is the load-bearing proposition of the cultural-historical tradition. It holds that abstract reasoning, voluntary attention, deliberate memory, planning, and self-regulation do not originate inside individual minds and then get communicated outward. They originate in social interaction and are subsequently internalized. The direction of developmental travel is from outside in, not inside out. The counting a child does silently in her head was first counting she performed out loud with her mother's hands. The planning an adult performs silently was first planning conducted in dialogue with a more capable other. This reversal changes the unit of psychological analysis from the individual to the relationship, and transforms any tool that participates in social-linguistic exchange — including AI — from a productivity instrument into a developmental environment.
