When I wrote that last sentence, which describes exactly what I saw, I thought it might be useful to place at the end of my book, when it’s published, underneath any “Errata,” a few “Non-Errata” and to say: the words “this uncertain movements” on page so-and-so is correct, with the noun in the plural and the demonstrative pronoun in the singular. But what has that to do with what I was thinking? Nothing, which is why I allow myself to think it.
