Big-endian versus little-endian. i.e. which end to crack a boiled egg to scoop out the contents with a spoon. (The other end goes in the egg cup). Gets some use in computer science due to the way certain numbers are stored in memory, and also with date formats. US format is middle-endian. Got to wonder how Swift would have run with that observation.

The allegory of the cave is deeper than that. Sure, perhaps there are unseen others guiding your world view, but it can go the other direction into the concept of qualia and the nature of perception itself. Perhaps some façades are necessary as we wouldn’t be able to perceive anything otherwise.
