The original mistake in every sentence: metaphor. Metaphor consists in giving the thing a name that belongs to something else; “the presentation of facts of one category in the idiom appropriate to another.” The original sentence, the original metaphor: Tat Tvam Asi, Thou art that; or hoc est corpus meum, this is my body. Making this thing other: “We already and first of all discern him making this thing other.” Metaphor is mistake or impropriety; a faux pas, or slip of the tongue; a little madness; petit mal; a little seizure or inspiration.
