 Thus what is most distinctive in Bradwardine’s theory is his “multiple-meanings” theory of signification.

There is considerable controversy over its correct interpretation (for a careful discussion, see Dutilh Novaes 2009: §1). (P2) is interpreted by Spade (1981:120) as what he calls “Bradwardine’s Principle” (BP):
