Excluded Middles

Aristotle’s third law of thought, the law of the excluded middle, has enjoyed a long and to some degree controversial history. Briefly, it posits that a statement must be either true or false, excluding any middle ground, which on the face of it makes perfectly good sense. Extrapolating from the domain of logic to the social world, however, the excluded middle takes on a different and indeed opposite connotation, for its absence spells not propositional rigor but cultural disaster.
