Aphanisis
In psychoanalytic theory, aphanisis (; from the Greek ἀφάνισις "aphanisis", "disappearance") is the disappearance of sexual desire. The etymology of the term refers to it as the absence of brilliance in the astronomical sense such as the fading or the disappearance of a star. The term was later applied to the disappearance of the subject. Jones. According to the theories of Ernest Jones, who coined the term in 1927, "aphanisis" is the foundation of all neuroses. Jones suggested that fear of "aphanisis" was in both sexes more fundamental than castration anxiety, an argument he used against Sigmund Freud in their  debate over female sexuality. Jones considered that the Oedipus complex confronted each sex with the threat of "aphanisis", and the choice of giving up "either their sex or their incest". Jones originally proposed "aphanisis" as a condition of female subjects based on their physiological characteristics. He stressed that women depend more, for physiological reasons, on men for their sexual satisfaction and that the loss of sexual desire is associated with abandonment. Jones subsequently linked "aphanisis" to Freud's concept of the trauma of separation, a point taken up by John Bowlby in the context of his own theory of separation  anxiety. Lacan. Lacan adapted Jones's term to a new meaning: ""aphanisis" is to be situated in a more radical way at the level at which the subject manifests himself in this movement of disappearance...the "fading" of the subject". He diverged from Jones' theory by maintaining that this phenomenon does not have a purely physiological basis, arguing that it is in the plane of intersubjective desire based in the signifier. In Lacanian theory, "aphanisis" describes the process through which a subject is partially eclipsed behind any signifier used to conceive of him/her: "when the subject appears somewhere as  meaning, he is manifested elsewhere as 'fading', as disappearance..."aphanisis"". The subject as such is, accordingly, barred and riven by the Other (of language), a subject has no choice but to conceive of themself "vis-a-vis" something other than their self, something 'outside' or radically separated from them. Because the Other is the sole means through which a 'subject' can be rendered thinkable, "aphanisis", the disappearance or the fading of the subject behind any signifier used to conceive of it, is an essential concept for understanding subjectivity and the peril of the subject's fundamental emptiness. Žižek developed the  concept of "aphanisis" in terms of the dialectic of presence and absence—the gap between the core of the personality and the symbolic narrative in which the individual lives. Literary examples. Montaigne has been seen as a classic example of the exploration of the "aphanisis" of the subject.
