Does 'Consciousness' Exist?

In his essay “Does Consciousness Exist?”, William James explains his assumptions about the material preconditions of consciousness, which in his opinion is based on so-called “pure experience”. He abandons the tradition of a transcendent definition of consciousness and lays the foundations for the advancement of what will later be called behaviorism. Consciousness, in his opinion, is biologically based and expresses itself in our behavior that needs to be investigated.
