He lives, then, on ginger-nuts, thought I; never eats a dinner, properly speaking; he must be a vegetarian then; but no; he never eats even vegetables, he eats nothing but ginger-nuts. My mind then ran on in reveries concerning the probable effects upon the human constitution of living entirely on ginger-nuts. Ginger-nuts are so called because they contain ginger as one of their peculiar constituents, and the final flavoring one. Now what was ginger? A hot, spicy thing. Was Bartleby hot and spicy? Not at all. Ginger, then, had no effect upon Bartleby. Probably he preferred it should have none.
-Herman Melville, "Bartleby, the Scrivener"
