This expert polemic on the nature of psychological momentum in creativity uses Mann's lifelong experience of "emotional" and, later, actual exile. The discussion combines considerations of objectivist theory and aesthetics, suggesting that neither private dynamics (including the expressive or adaptational vicissitudes

thereof) nor cultural and historic influence can explain major artistic production. Artistic force, according to this view, both shapes and is shaped by all of these. The reading of the Eissler and Rosenwald papers back-to-back is recommended.
