First of all, I wasn't quite sure where this should go, so any mods should feel free to move or delete this if it's in the wrong place.
But, now to the actual question. Part of the criteria of a paper I'm writing is that it doesn't include first or second-person nouns or pronouns, and I was wondering if referring to yourself as "this one" or even just "one" would be a grammatically correct third-person substitute for those.
And is case you are wondering, here is an example of how I used it in text. "This one is willing to wager one’s life that not one person in this room knows what it is like to live with schizophrenia."
