Self, ego, affects, and drives.

I have explored the concepts of self, ego, affects, and drives, with special emphasis on terminological confusions and Freud's use of Selbst and Ich. I have also proposed a modification of the dual instinct theory in the light of the relation between affect and drives. Finally, I have proposed a developmental model on the basis of all the above considerations, and stressed its relevance for the classification of nonorganic psychopathology.
