Duality In Sigmund Freud's Fetisha

Freud's Fetishism takes a psychoanalytical approach to understanding object-oriented sexual attraction. As a consequence of repression, Freud suggests that it is in early childhood when the fetish is formed, specifically in young males. Furthermore, the fetish is a 'substitute for the penis'; Freud proposes that as a young boy perceives that a woman does not possess a penis, he comprehends it as a form of female castration. Once he has observed the woman, there is a conflict between his original belief of her having a penis just like him, and his discovery that she, in fact, lacks. Consequently, this new discovery installs fear in the young boy, 'for if a woman had been castrated, then his own possession of a penis was in danger', that is, he is threatened by the same fate. Therefore, in order to overcome this newfound fear, the psyche substitutes the castrated female penis; this substitute becomes a mechanism for processing the 'horror of castration'. The woman, in his mind, still has a penis but it is 'no longer the same as before'. Thus, the assigned replacement has a sense of duality, it becomes both a 'token of triumph over the threat of castration and a protection against it'.
Explaining the differences between the two, Freud states that the former is a result of 'the ego, in service of reality, suppresses a piece of the id' (being the part of the mind where impulses and primary processes manifest), whereas psychosis 'lets itself be induced by the id to detach itself from reality'. It is both 'both the disavowal and the affirmation of the castration [that] have found their way into the construction of the fetish itself'; the fetish both suppresses the memory whilst simultaneously allowing the instinctive replacement of the penis, thus, enabling a detachment from the horrific
