As part of a continuing effort to recast traditional metapsychological perspectives in terms that are not based on discredited classical concepts of instinctual drive and psychic energy, the dynamic principle is reformulated in strictly motivational terms that extend the implications of a previous recasting of the economic principle in terms of an economics without energies. The approach taken is by way of refocusing Rapaport's classic rendering of the drive-and-energy theory of motivation in terms of intentionality, purpose, and appetitive desire. The present essay undertakes the first part of the discussion through a putative dialogue with Rapaport's exposition, and a clarification of motivational terms. Issues related to determination, nondrive motivation, and drive characteristics as proposed by Freud are discussed.
