Abstract
ROBERT L. CAMPBELL replies to commentary on his article, "Ayn Rand and the Cognitive Revolution in Psychology" . He comments briefly on Richard Shedenhelm's historical analysis of the "counting crows" experiment. He agrees with Barry Vacker's view that nonlinear dynamics are required in any analysis of skill and implicit knowledge, but contends that Rand's explicit epistemological formulations exclude these dynamics and prevent her from offering an adequate treatment of the implicit. Campbell also responds to Will Thomas's comments made in the journal, Navigator. He finds that Thomas has accepted the critical role that psychology must play in an epistemological theory of concepts
