«Funes the Memorious is as Borgesian a character as they come, a man tormented by his hyperencylopedic mind, tragically unable to forget anything. “I alone have more memories than all mankind has probably had since the world has been the world,” Funes laments. Seemingly fulfilling the most hubristic of human ambitions—to remember/know everything—he is incapacitated by the compulsive absoluteness of his knowledge, unable to think and communicate with the rest of the humanity. Casting himself as the imperfect, inferior countercharacter to Funes, Borges suggests that forgetting—that is, forgetting ceaselessly—is essential and necessary for thought and language and literature, for simply being a human being.»

Hyperthymesia is the condition of possessing an extremely detailed autobiographical memory. Hyperthymesiacs remember an abnormally vast number of their life experiences.

Elizabeth Parker, Larry Cahill, and James McGaugh (2006) identified two defining characteristics of hyperthymesia: Spending an excessive amount of time thinking about one’s past, and displaying an extraordinary ability to recall specific events from one’s past.[1]

The word hyperthymesia derives from Ancient Greek: hyper- («excessive») and thymesis («remembering»). Hyperthymesia is also known as hyperthymestic syndrome[1] and highly superior autobiographical memory (HSAM)

Individuals with hyperthymesia can recall almost every day of their lives in near perfect detail, as well as public events that hold some personal significance to them. Those affected describe their memories as uncontrollable associations, when they encounter a date, they «see» a vivid depiction of that day in their heads.[3] Recollection occurs without hesitation or conscious effort.

It is important to draw a distinction between those with hyperthymesia and those with other forms of exceptional memory, who generally use mnemonic or similar rehearsal strategies to memorize long strings of subjective information. Memories recalled by hyperthymestic individuals tend to be personal, autobiographical accounts of both significant and mundane events in their lives. This extensive and highly unusual memory does not derive from the use of mnemonic strategies; it is encoded involuntarily and retrieved automatically.[4] Despite being able to remember the day of the week on which a particular date fell, hyperthymestics are not calendrical calculators like some people with autism or savant syndrome. Rather, hyperthymestic recall tends to be constrained to a person’s lifetime and is believed to be an unconscious process. (…)
