Text: "The fourth law of logic." Advances a fourth law of logic to be added to the three axioms of classical Aristotelian logic. The fourth law addresses the presently excluded middle and directly contradicts it by assuming that two opposites are identical on their common boundary. The law has two methods of application: (a) A thing is that which it does, and does that which it is, and (b) collecting the totality of a thing turns it into its own opposite.
