Sigmund Freud,
Totem and Taboo
“ He who approaches the problem of taboo from the field of psychoanalysis, which is concerned with the study of the unconscious part of the individual’s psychic life, needs but a moment’s reflection to realize that these phenomena are by no means foreign to him. He knows people who have individually created such taboo prohibitions for themselves, which they follow as strictly as savages observe the taboos common to their tribe or society. If he were not accustomed to call these individuals ‘compulsion neurotics’ he would find the term ‘taboo disease’ quite appropriate for their malady. ”
