Volume 2, Number 1

This issue broadens the journal's scope while keeping the same central question in view: how do ideas spread, stabilize, and become part of shared culture? The articles range from abstract evolutionary models and semantic fractals to the Principia Cybernetica project and a direct look at the relationship between brain and mind. It is a characteristic specimen of the period, and a reminder that the journal was already pressing on questions that remain unsettled.
