Additional notes

The author explicitly describes this diagram using the terminology of the Aristotelian relations: "These two negations of each of the two contraries, constitute the subcontraries a version of the logician's square of contraries. [...] We have then the following configuration of these terms in which the negations or contradictories joined by the diagonals" (p. 370).
