?

?
Think about whether this reason is strong or weak
2.If necessity were solely grounded in what subjects are, mathematical truths about physical objects would require no empirical supplementation, which Aristotle denies in Physics II.
?
Think about whether this reason is strong or weak

Reason against 2 of 2

1.Aquinas and Scotus both argue that essential predication admits degrees of necessity, so 'on account of what they are' underdetermines which essentialist claims license demonstration.
?
Think about whether this reason is strong or weak
2.A subject's essence can ground conflicting demonstrative necessities when the same subject falls under multiple scientific domains, as in the case of harmonics and arithmetic.
?
Think about whether this reason is strong or weak

It is not, however, enough for a principle of demonstration to be true; it must also be necessary. A necessary conclusion follows from necessary premises (NLP I. 19, 110–113). The kind of universality required for demonstration is not the same as that of a universal acquired through abstraction, which is said of many (ut dicatur de multis)—the kind described in the Perihermeneias and in Porphyry’s Isasoge—but the universal that must be said of all and always (de quodlibet et semper et primo).[2
