> The idea is a possible realization of LANGUAGE 18 from "FORTY-FOUR ESOLANGS":

    a sculptural language

    it subtracts from potential algorithms,
    making them more specific

    a program only states what it doesn't do

This made me want to read the other forty-three proposals for esolangs! Some of them are here [0], buy the book for more.

I'm a bit unclear about how much the book specifies Language 18 (is it really just the three-line prose poem above? Other languages seem to have more detail) and how much came from the author of this post.
