What’s the right policy for capitalizing words after colons? Why?
Here’s an example I just wrote:
Both emphasize fallibility: [“We” or “we”] will inevitably make mistakes, so we need philosophical thinking (including criticism) to help us find and fix mistakes.
I read some stuff that said only capitalize proper nouns in British English and don’t capitalize if you’re putting a list after the colon. And don’t capitalize if the stuff after the colon is a sentence fragment. But for American English, people keep saying you can but don’t have to capitalize if you write a complete sentence after the colon.
DD told me a policy he used for this. I don’t clearly remember it, but I might have been to capitalize if the rest of the paragraph all follows the colon, and lowercase if just the rest of that sentence follows the colon and then the next sentence is separate.
