Quite a bit, apparently. Recent research suggests that the same part of the brain which helps us see space and navigate through it also guides us through the thinking process. As we remember and reason, we’re taking a spatial tour of memories and possibilities.
This is precisely how classical and medieval scholars, actors, and orators carried knowledge with them. They would meticulously construct memory palaces by memorizing spatial locations, like cathedrals, areas, palaces, and parts of cities, which they would then mentally place powerful images in to help them remember facts and ideas.
It’s easy to think about the power of such locations when we think about our earliest memories. You may not remember what was on TV in a given year of your childhood, but I’ll bet you remember what the TV looked like and where in the room it was placed. Your whole childhood home, or series of homes, is probably indelibly imprinted on your mind. This same fantastic staying power of visual memory can be knowingly harnessed. In the era before paper and Google, it was probably how troubadours memorized long songs on a single hearing, or how orators could speak for hours on end using a predetermined sequence of ideas.
We can’t enter the mansions of memory any more, thanks to information tech in all its forms, but it seems like we’re hardwired to want to be there.
Anybody out there use a memory palace or anything like it?
