Substances 'substand' (beneath accidents), or 'subsist' (independently) [Eustachius]
|
|
Full Idea:
It is proper to substance both to stretch out or exist beneath accidents, which is to substand, and to exist per se and not in another, which is to subsist.
|
|
From:
Eustachius a Sancto Paulo (Summa [1609], I.1.3b.1.2), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 06.2
|
|
A reaction:
This reflects Aristotle wavering between 'ousia' being the whole of a thing, or the substrate of a thing. In current discussion, 'substance' still wavers between a thing which 'is' a substance, and substance being the essence.

Prime matter is free of all forms, but has the potential for all forms [Eustachius]
|
|
Full Idea:
Everyone says that prime matter, considered in itself, is free of all forms and at the same time is open to all forms - or, that matter is in potentiality to all forms.
|
|
From:
Eustachius a Sancto Paulo (Summa [1609], III.1.1.2.3), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 03.1
|
|
A reaction:
This is the notorious doctrine developed to support the hylomorphic picture derived from Aristotle. No one could quite figure out what prime matter was, so it faded away.

'Haecceitism' says that sameness or difference of individuals is independent of appearances [Kaplan]
|
|
Full Idea:
The doctrine that we can ask whether this is the same individual in another possible world, and that a common 'thisness' may underlie extreme dissimilarity, or distinct thisnesses may underlie great resemblance, I call 'Haecceitism'.
|
|
From:
David Kaplan (How to Russell a Frege-Church [1975], IV)
|
|
A reaction:
Penelope Mackie emphasises that this doctrine, that each thing is somehow individuated, is not the same as believing in actual haecceities, specific properties which achieve the individuating.

If quantification into modal contexts is legitimate, that seems to imply some form of haecceitism [Kaplan]
|
|
Full Idea:
If one regards the usual form of quantification into modal and other intensional contexts - modality de re - as legitimate (without special explanations), then one seems committed to some form of haecceitism.
|
|
From:
David Kaplan (How to Russell a Frege-Church [1975], IV)
|
|
A reaction:
That is, modal reference requires fixed identities, irrespective of possible changes in properties. Why could one not refer to objects just as bundles of properties, with some sort of rules about when it ceased to be that particular bundle (keep 60%?)?
