I have learned somewhere (or maybe decided ) that any number used as a pronoun -- that is, X standing alone to represent the already stated group of X nouns -- should be spelled out, no matter how big the number. Do you know of such a rule? I see no mention of it in the Chicago Manual, which is our house manual.
The sentence I have before me is something like: "From age 54 until his death, he wrote some 271 theological works in addition to the 142 in science." I'm thinking that "142" should rightly be spelled out to give it the physical weight of its thing-ness. Yes?
Note: In this case I will simply rephrase it as "his 142 works in science" rather than spell out so big a number, but still I'd like to know whether this number-as-pronoun rule even exists. Thanks.
