Re: predication and genus

If there is a genus F, then is it the case that for all x, if x is F, x must be in the genus F? If you say that there is a genus F, then you are saying that there are species which are defined with F as their genus. Of such species which belong in genus F, F is predicated of them. Every genus is pr...

Re: Is the Unmoved Mover in a genus?

Thank you, -1-. I had been thinking something similar but not identical, i.e. that the First Mover is the sole member of a species within the genus of movers. And of course, from the POV of Aristotle's categories, the genus in play here is not in the category of substance but relation or maybe possi...

Is the Unmoved Mover in a genus?

I posted this in the Logic and Philosophy of Math subforum but was advised to post here. My question was, from an A-T point of view, if something has a predicate F, is it in a genus or species F? I am thinking of genus as in Aristotle's Categories and throughout his works. In Ari, a genus is a "kind...

Re: predication and genus

Thank you. I've only posted 6 times on here, or thereabouts. But I'll try moving this to the religion subforum. I posted here because I thought the question of predication and genus had to do with logic.

Re: predication and genus

Many thanks for answering. I am thinking of genus as in Aristotle's Categories and throughout his works. In Ari, a genus is a "kind," which is divided into species by various differentiae. I.e. "There are kinds in the sense in which plane is the kind of plane figures and solid of solids; for each of...

predication and genus

If there is a genus F, then is it the case that for all x, if x is F, x must be in the genus F? (In asking this question I leave out the problem of analogical predication of names of God.)

Thank you, f

Re: Problem with Aquinas' Third Way?

Actually, Thomas himself notes that in natural corruption, the matter persists while the form is replaced by another form: “in generatione naturali quando corruptio unius est generatio alterius per hoc quod forma una inducitur et alia expellitur, remotio formae praeexistentis se tenet ex parte causa...

Re: Problem with Aquinas' Third Way?

Thank you for the answers, everyone. I may be unfamiliar with a discussion somewhere within Aquinas' vast corpus. As far as I'm aware, he does not demonstrate that when something passes away, it passes away into pure nothingness. As I said in my OP, it seems to me that he trades on this possibility ...

Problem with Aquinas' Third Way?

Here is another "issue" of mine with Thomism. In his Third Way of proving God’s existence (ST 1a Q. 2 Art. 3), Aquinas appeals to our experience that some things can exist or not exist, since things are found to be generated and pass away. But when a thing passes away, on Aristotelian assumptions, i...

Thomist analogical predication - problems

I have various "issues" with Thomism and am not sure whether I'm right when I suspect errors in that system. I post one "issue" here, in case anyone would like to discuss, and I'll make a separate thread for another one. Aquinas’ doctrine of analogical predication does not seem to escape the difficu...
