This second paper extends the discussion of the previous analysis of the dynamic principle in psychoanalysis exclusive of considerations of drive-derivation. Basic motivational principles are extrapolated to include considerations of the nature of motivation, particularly focusing on the distinction of causality vs. motivation—motivation is attributed to complex configurations of internal and external stimulus conditions giving rise to eliciting circumstances acting in the order of intention and purpose, while causality deals with execution as a function of the action of the self-as-agent. Topics discussed include wish-fulfillment, unconscious wishes, wish vs. will, desire, desire vs. drive, motives vs. affects, motivational schemata, sexual desire and sexual drive, sexual excitement, sadomasochism, implications for interpretation, and the variety of motives involved in transference vs. alliance. The discussion concludes with a reformulation of the classic dynamic viewpoint as one of the essential metapsychological assumptions.
