 This temporal understanding of the simple vs. as-of-now distinction is the one adopted by most authors, both before and after Burley (however, see Pseudo-Scotus’ formulation, discussed in the next section), and is repeated verbatim in the longer version of On the Purity… (p. 146). Another interesting feature of the shorter version is the fact that it treats syllogisms under the concept of consequence, thus illustrating the absorption of syllogistic by theories of consequences in the 14th century. Burley’s mature theory of consequence, as presented in the longer version of De Puritate, is best discussed against the background of the theory of consequence presented in Ockham’s Summa Logicae, so let us now turn to Ockham first.
