Franciscus de Mayronis and Petrus Thomae: The Principle of non-contradiction is univocally common to God and creatures

The claim that the principle of non contradiction (PNC) is univocally common to God and creatures is a common one in early Scotism. I give below the summary conclusions from the prologue of Mayronis' Conflatus redaction of his commentary on the Sentences. There is a link to Latin text on the sideboard of the blog.

Franciscus de Mayronis, Conflatus, prol. q. 1 a. 2.

Conclusio 1: "First is that that principle or its truth is found formally in creatures" [a proof follows; here I give only a little text in what follows]
Conclusio 2: "The second conclusion is that the truth of the principle is formally found and also holds in God, because where the conclusion, there the principle, just as before. In God is found the truth of that, namely that God is eternal or non eternal, which are conclusions of the first principle."
Conclusio 3: "The third conclusion is that it is found under the same ratio in God and in creatures" [several arguments follow]
Conclusion 4: "The fourth conclusion follows from the third, from which under the same formal ratio it is found in God and creatures it follows that one and the same is found in God and creatures."

perhaps if I have time, I will translate this whole section.


Here is the text from Petrus Thomae's Reportatio, d. 1 q. 1:

Tertiadecima ratio formatur ex tertiadecima maxima sic: omnis principii veritas se extendit ad univoca sui subiecti et nullo modo ad aequivoca; sed veritas huius principii ‘de quolibet affirmatio vel negatio’ vera se extendit ad ens creatum et increatum, finitum et infinitum etc. ergo creatum et increatum finitum et infinitum sunt univoca sui subiecti; sed subiectum eius est ens; ergo ens est univocum ad ens creatum et increatum, finitum et infinitum; ergo.

The thirteenth argument is formed from the thirteenth maxim thus: the truth of every principle extends itself to the univocals of its subject and in no way to equivocals; but the truth of this proposition 'affirmation or negation of whatever' truly extends itself to created and uncreated being, finite and infinite, etc.; therefore created and uncreated, finite and infinite are univocals of its subject; but the subject of it is being; therefore being is univocal to created being and uncreated being, finite and infinite; therefore,
