Internal relations combine some tropes into a nucleus, which bears the non-essential tropes [Simons, by Edwards]
|
|
Full Idea:
Simons's 'nuclear' option blends features of the substratum and bundle theories. First we have tropes collected by virtue of their internal relations, forming the essential kernel or nucleus. This nucleus then bears the non-essential tropes.

From:
report of Peter Simons (Particulars in Particular Clothing [1994], p.567) by Douglas Edwards - Properties 3.5
|
|
A reaction:
[compression of Edwards's summary] This strikes me as being a remarkably good theory. I am not sure of the ontological status of properties, such that they can (unaided) combine to make part of an object. What binds the non-essentials?

Bodies, properties, relations, events, numbers, sets and propositions are 'things' if they exist [Lowe]
|
|
Full Idea:
Not only material bodies but also properties, relations, events, numbers, sets, and propositions are—if they are acknowledged as existing—to be accounted ‘things’.
|
|
From:
E.J. Lowe (Things [1995])
|
|
A reaction:
There might be lots of borderline cases here. Is the sky a thing? Is air a thing? How is transparency a thing? Is minus-one a thing? Is an incomplete proposition a thing? Etc.

Descartes says there are two substance, Spinoza one, and Leibniz infinitely many [Cottingham]
|
|
Full Idea:
Descartes was a dualist about substance, Spinoza was a monist, and Leibniz was a pluralist (an infinity of substances).
|
|
From:
John Cottingham (The Rationalists [1988], p.76)
|
|
A reaction:
Spinoza is appealing. We posit a substance, as the necessary basis for existence, but it is unclear how more than one substance can be differentiated. If mind is a separate substance, why isn't iron? Why aren't numbers?
