Abstract
This work consists on a treatment of interdiction and silence within the fields of Psychoanalysis and Discourse Analysis. This task will take place with a use of the Aristotelian logic both alethic (necessary, impossible, possible, contingent) and deontic (obligatory, prohibited, permited, facultative). We propose that categories like silence, interdiction, prohibition, prohibition of incest, censorship, and Law can be approached by Modal Logic. We specifically argue that these categories from Discourse analysis and Psychoanalysis have alethical and deontical aspects, and that the deontic is a manifestation of the aletic.
