Abstract
This article analyzes the extended mind hypothesis that has been discussed during the past two decades following the article “The Extended Mind” by Andy Clark and David Chalmers. It examines the position of active externalism and notes the shortcomings of the arguments supporting this position as proposed by Clark and Chalmers. It is demonstrated that the cultural-historical psychology developed by Vygotsky represents an alternative means of substantiating the extended mind hypothesis. Interpreting Vygotsky’s position as “active social externalism,” the author contrasts Vygotsky’s theory with the active externalism of Clark and Chalmers, as well as with the classical externalism advocated by Putnam and Burge, showing the advantage of Vygotsky’s approach. This advantage has been seen in the ability of Vygotsky’s active social externalism to avoid the problems faced by other externalist approaches to explaining the mind.
