“
Today we have books, photographs, computers and an entire superstructure of external devices to help us store our memories outside our brains, but it wasn’t so long ago that culture depended on individual memories. A trained memory was not just a handy tool but also a fundamental facet of any worldly mind. It was considered a form of character-building, a way of developing the cardinal virtue of prudence and, by extension, ethics. Only through memorizing, the thinking went, could ideas be incorporated into your psyche and their values absorbed.”
