“Do you know the abandoned practice of humorism, passed down by the Hamites of Egypt to the Greeks and Romans? It held that each of man’s bodily fluids governed a principle: blood for life; yellow bile the seat of aggression; black the cause of melancholy; and phlegm, apathy. I believe one humor is yet unaccounted for. What men call hate. You and I have seen too much to discount its existence.”
