Like most Scotists, Peter defends the analogy of the concept of being and holds that the univocal concept of being is compatible with an analogical concept of the same.
First I give an argument that illustrates the systematic nature of the treatise. Peter stitches together various conclusions that he has proven in other questions, leaving univocity as the only surviving option.
Petrus Thomae, Quaestiones de ente q. 10 a. 1
Major premise: "Furthermore, if the concept of being is not univocal, this will be because  being does not have a proper concept, or  because its concept is denuded and despoiled from every ratio, or because with [univocity] posited, the  analogy of beings [analogia entium] and  simplicity of the first being cannot be preserved."
Minor premise: "But  does not impede from the fourth and fifth question, nor  from the ninth question, nor  from the seventh question, nor  from the sixth question and what follows (in the tenth question)."
Second, I give an argument from the same section, in which Peter is showing that the denial of univocity is impossible.
Fifth: if the concept of being is not univocal to God and a creature, therefore through the first principle nothing can be proved of God, which is unfitting. The consequence is proved thus: being [esse] is verified of every positive; but God is of this kind; therefore etc.
I ask in what way is 'being' [esse] taken in the major? For either it means the concept of created being, and then the minor is not taken under the major, or it means precisely the concept of uncreated being, and then the principle is begged [petitur principium], or it means in act the concept of created and uncreated being, and then there will be four terms in the syllogism. Therefore unless being means a proper univocal concept to created being and uncreated being, nothing will be able to be proven of God through some proposition in which being is predicated.
