In search of the unknown: introduction to the special issue.

The problem of aesthetic perception occupied Vygotsky throughout his life. Working in different research collectives or networks he worked out different answers but never reached a final solution. Inadequate and incomplete access to his writings unfortunately hinders us from understanding Vygotsky's ideas and his personal motives. Publication of his notebooks and unadulterated versions of his writings plus an analysis of his research networks will deepen our understanding.
