The act of writing and the effects of supplying are overstated in this paper. Thus, this is a study of the premises of what is understood of writing and supplying from the psychoanalysis point of view. From this premise, we seek to find the purpose of the act and the activity that involves writing. Thus, we conducted a study based on the investigation of paradigmatic cases of Schreber and Joyce as well as group of patients from the Caps that belong to the workshop that approaches reading and writing. Further, our hypothesis is that the act of writing promotes methods of supplying that was named based on the terms used by Allouch from a delirium transcript and transliteration.
