An emperor stripped his own dinner down to a corpse and grape juice

At a Roman dinner, the roast meat is carried in glistening, the wine is poured, the host's purple-edged robe catches the lamplight. Marcus Aurelius, at some point in his own notebook, sat through exactly this kind of scene and did something deliberately unglamorous with it: he took the meal apart.

How good it is, he wrote, when you have roast meat before you, to impress on your mind that this is the dead body of a fish, this the dead body of a bird or pig. The prized Falernian wine, he goes on, is simply the juice of grapes. The purple-edged robe that marks out status and rank is nothing more than the hair of a sheep soaked in shellfish blood. He does the same with sex, describing it in blunt anatomical terms designed to strip away every trace of romance or importance the imagination had draped over it.

This technique had a name in the philosophical vocabulary of the day, merismos, a breaking into parts. Marcus treats it as one of the working tools of philosophy, alongside the harder discipline of picturing the universe as a single whole. The two moves point in opposite directions, but they serve the same goal, because for Marcus one of the most reliable ways a person loses their footing is by being seduced by the appearance of a thing rather than its plain material reality. He names the danger directly: vanity is the greatest seducer of reason, and you are most under its spell exactly when you are most convinced that whatever you are chasing matters enormously.

This is not an argument that food, wine, or clothing are worthless, or that pleasure is shameful. Marcus Aurelius is not trying to make anyone hate dinner. He is trying to break a specific kind of spell, the one where a robe becomes a symbol of superiority, or a title becomes proof of your worth, simply because no one has bothered to look closely at what the thing actually is underneath its own advertising. Strip away that boastful account of itself, he writes, and you can see it naked, for what it is, and then decide with a clear head whether it deserves the pull it has on you.

Pick one desire that currently has more grip on you than you would like, a purchase you are chasing, a title you want, a comparison you keep making. Describe it in its plainest material terms, stripped of every story about status or meaning you have layered on top, the way Marcus Aurelius reduced a purple robe to dyed sheep's hair. Notice exactly which layer you added yourself and where it came from. Do this deliberately before any moment when you are about to act on impulse, and let the stripped-down description sit for a moment before you decide. Keep this tool for things that seduce you, not for the people or duties you actually value.
