Petrus Thomae's De ente: Prologue

Here is a translation of the prologue from the Quaestiones de ente, the critical edition of which was recently published here.

[Quaestiones de ente]

[Prologue]

Just as the Philosopher says in I Physics chapter 7, “first according to nature we say common things and thence speculate about proper things.” For with common things unknown, so also are proper things unknown, according to him elsewhere, and therefore “it is necessary to proceed from universals into singulars,” from I Physics chapter 1. Since therefore the transcendentals are the most common, it is opportune to treat something of them for the acquisition of scientific knowledge; among the transcendentals being itself holds the first and chief place, as will be seen below. And therefore, in order to acquire knowledge of the transcendentals, we will procede in this order: first we will inquire about the concept of being, second about what follows [consequentibus] it, third about the first parts of being.

Concerning the first [part] we proceed thus:

First we ask whether the concept of being is known per se or is knowable from others

Second whether the concept of being is quidditative

Third whether the concept of being is maximally first

Fourth whether being has a proper concept distinct from the concept of every special being

Fifth whether the argument from a certain and doubtful concept concludes necessarily

Sixth whether among quidditative concepts only the concept of being is irreducibly simple

Seventh whether true analogy and true univocity are compatible in the same concept

Eighth whether the concept of being is one only by a unity of equivocation

Ninth whether the concept of being is one only by a unity of confusion

Tenth wehther the concept of being is one by a unity of univocity

Eleventh whether the univocity of the concept of being is real

Twelfth whether being is predicated ‘in quid’ of its proper attributes

Thirteenth whether being is predicated ‘in quid’ of ultimate differences

Fourteenth whether the concept of being is immediately contractible by some differences

Fifteenth whether there can be something univocal to real being and being of reason.
