SYMBOLS: Elements in the world that have come to hold specific, if repressed, sexual meaning for the human species. According to Freud, the displacements and condensations effected by repression can sometimes take on such rigid form that that take on the quality of symbols, which, according to Freud, have similar meanings for all humans. In other words, such repressions become phylogenetic: they speak to the whole development of the human race and constitute a racial heritage. For this reason, Freud sometimes referred to the id as the inheritance of the species. C. G. Jung broke from Freud in 1913 and pursued this aspect of psychoanalytical theory, in particular.
