Borges´ memory was famously prodigious. But just as exceptional was his appetite for books. If you read his lectures or transcribed dialogues, you will feel that he has read everything He could cite the most obscure writers of any epoch and region by heart. Persian myth, medieval German writers, ancient Japanese poets or monks, Scottish folklorists, theologians and heresiarchs, belonging to antiquity, the Middle Ages or recent times. You name it. And then he would relate all of those with daily occurrences. He would hear a rhyme from a street peddler, find in it an implicit philosophical paradox and recite a verse from ancient Carthage or a medieval Chinese tractate to provide a solution. He also had a penetrating intuition, and his conclusions, reached by himself through personal intuition and later woven into his stories, often turn out to be confirmed by later scientific research. It´s hard to understand how he managed to grasp reality with such depth. It really seems as if his mind was of a greater order of complexity than that of mere mortals. In a way similar to Einstein´s.
