Cathexis and Field

Freud's image of Cathexis as a 'charged' interest implies a possible extension that neither he nor Marcuse considers.  As is the case in Electromagnetism, a multiplicity of charged items can, when in proximity, constitute a Field, in which their behaviors are interdependent.  The classical concept of Eros, as well as that of its popular Cupid incarnation, as mutual attraction, can be conceived as such a Field.  However, even as he ventures from Psychoanalysis into Social theory, Freud lacks the resouces to study individual behavior as determined by such collectives, which, as populated by Egos, is not to be confused with his concept of a Group, i. e. a mob, which is constituted by Ids.  Likewise, by accepting Freud's Social Atomism, Marcuse is hindered from even entertaining a concept that could enrich his model of an ideal society.
