 3      I,  14|          and knowledge of a thing’s essence must be affirmative; while
 4      I,  14|            cannot be universal, and essence must have a universal character:
 5     II,  4 |           of it as belonging to its essence. But in that case (1) the
 6     II,  4 |              2) if A inheres in the essence of all B and B is predicated
 7     II,  4 |           all C as belonging to C’s essence, A also must be predicated
 8     II,  4 |            of C as belonging to its essence.~If one does not take this

12     II,  4 |            premisses will predicate essence, and consequently B also
13     II,  4 |           be predicated of C as its essence. Since, therefore, both
14     II,  4 |            premisses as predicating essence, one cannot infer that A
15     II,  4 |           is the definable form and essence of C: but if one does so
