The book of the famous Russian philosopher and psychologist Vadim Rudnev is devoted to understanding the issues related to the construction of the logic of delusional ideas from the standpoint of the philosophy of everyday language and psychosemiotics, an interdisciplinary approach that the author of the book has long been developing in his research. The author introduces a number of new concepts, such as unconscious narration, concerted delirium and genuine delirium. Unconscious narration is a narrative that unfolds beyond the consciousness of its author.
