| It's a replacement for cumbersome constructions ("he or she", "himself or herself") to refer to a single hypothetical person of any gender.   "They" and "themselves" aren't plurals in this usage.... though you still treat them that way.   
 Ain't languages a beautiful thing?
 
 Personally, I'd be more concerned with making such a strong claim about human nature than numerical agreement.  You do back up the claim later in the paper, right?
