in psychology sexualism (Freud), or some other ‘ism,’ in so far as it could be shown that the investigators reduced the energy of the total psyche to one definite force or drive. But drives, as we have shown, are specific forms of energy.
Jung argues that treating sexual energy as the singular ground of all psychic life constitutes an inadmissible reduction; sexuality is a specific form of the broader energic concept, not its synonym.
