Psyche and Cathexis

The implicit heart of Freud's theory of the Psyche is the experience that, in translation, is termed 'Cathexis', meaning 'charged interest'.  In the experience, the object of Cathexis is perceived as charged, a reflection of the influence of Brentano's Intentionality on Freud, i. e. in which the appearing-charged of the object of perception is for the perceiver.  It is this electric-like characteristic of sexual desire that distinguishes it from other impulses, thereby explaining Freud's privileging of Eros over other drives, a focus that could be itself characterized as cathectic.
