Can the word "oneself" be considered a first or second person point of view? I'm trying to think of words I can use for my research paper, but I can't use first or second person words.
Not without using incorrect grammar.
One, and by extension, oneself, is a third person pronoun. However, if the paper isn't being graded on style or grammar, you could use oneself in reference to you.
"I ran 10 miles yesterday, one's self can be very energetic."
I personally would just stay away from using one as a pronoun in general, you can use it occasionally but if you end up using words like "oneself" whatever you're writing can feel pompous, and overdone.
