'One' can mean undivided and not a multitude, or it can add measurement, giving number [Aquinas]
|
|
Full Idea:
There are two sorts of one. There is the one which is convertible with being, which adds nothing to being except being undivided; and this deprives of multitude. Then there is the principle of number, which to the notion of being adds measurement.

A reaction:
[From a lecture handout] I'm not sure I understand this. We might say, I suppose, that insofar as water is water, it is all one, but you can't count it. Perhaps being 'unified' and being a 'unity' are different?

Serious essentialism says everything has essences, they're not things, and they ground necessities [Shalkowski]
|
|
Full Idea:
Serious essentialism is the position that a) everything has an essence, b) essences are not themselves things, and c) essences are the ground for metaphysical necessity and possibility.

A reaction:
If a house is being built, it might acquire an identity first, and only get an essence later. Essences can be physical, but if you extract them you destroy thing thing of which they were the essence. Does all of this apply to abstract 'things'.

Essences are what it is to be that (kind of) thing - in fact, they are the thing's identity [Shalkowski]
|
|
Full Idea:
The route into essentialism is, first, a recognition that the essence of a thing is "what it is to be" that (kind of) thing; the essence of a thing is just its identity.

A reaction:
The first half sounds right, and very Aristotelian. The second half is dramatically different, controversial, and far less plausible. Slipping in 'kind of' is also highly dubious. This remark shows, I think, some confusion about essences.
