06 · The distinction
Kept or survived
Did we keep this, or did this survive? Keeping is an act. Survival is what is left after weather, conquest, chance, and neglect have had their way.

Kept
Someone chose it. Copied it. Taught it. Loved it enough to say it again.
Survived
Weather, chance, fire, neglect. What remains may be durable, convenient, or flattering. Survival is not a moral.
A canon is a decision about what a people will copy. A school curriculum is a decision about which lines a child must carry. A museum is a decision about which objects will be climate-controlled while others return to dust. Censorship is a decision too, in the other direction.
Chance is not a decision. A tablet baked in a fire that was meant to destroy a city. A story overheard by a collector. A file format that outlasts its author. A motto that slips its family and puts on a nation's clothes.
Did we keep this? Then someone chose it, copied it, taught it, funded it, hid it, or loved it enough to say it again.
Did this merely survive? Then the thing that remains may be the durable fragment, the convenient fragment, or the fragment that flattered the next teller. Survival is not a moral.
After the institutional afterlife of a text is felt, Civilizations. The line stays with how it is carried, distorted, and sometimes believed because it was beautiful.
