Whenever Montaigne did exert himself to flick through a book, according to him, he promptly forgot almost everything he had read. “Memory is a wonderfully useful tool, and without it judgment does its work with difficulty,” he wrote, before adding, “it is entirely lacking in me.” There is no man who has less business talking about memory. For I recognize almost no trace of it in me, and I do not think there is another one in the world so monstrously deficient.
