Everything is act, is purposive action. Purpose implies choice and choice a projection of possibilities and a frame or map or model to hold them. These are not separate parts but integral to the one event as is the time and space and world in which the correlative objects appear. In this the subject is just another kind of object since the actor is an essential part of the model o the action. If there is a self it does not resemble any synthesis of such subjects and so does not occupy a position as it were 'behind' the action. This picture however leaves ego and egoism unexplained. Why is there so much energy invested in the surplus of subjectivity?
