9. Objects / B. Unity of Objects / 2. Substance / a. Substance
Corpuscularianism promised a decent account of substance [Pasnau]
     Full Idea: One of the great attractions of corpuscularianism is that it promises to put our acquaintance with substances on a solid foundation.
     From: Robert Pasnau (Metaphysical Themes 1274-1671 [2011], 07.3)
     A reaction: This is why the seventeenth century did not abandon 'substance', even though they banished 'substantial form'.
Corpuscularian critics of scholasticism say only substances exist [Pasnau]
     Full Idea: Corpuscularian critics of scholasticism tend to think that only substances exist.
     From: Robert Pasnau (Metaphysical Themes 1274-1671 [2011], 06.2)
     A reaction: Pasnau treats this as an extreme 17th C reaction which was hopelessly inadequate as metaphysics. We have been struggling with the nature of 'properties' ever since, while losing our grip on the concept of a unified 'substance'.
Scholastics wanted to treat Aristotelianism as physics, rather than as metaphysics [Pasnau]
     Full Idea: There is a broad scholastic tendency to understand Aristotelianism not in abstract, metaphysical terms, but as a concrete, physical theory of the world.
     From: Robert Pasnau (Metaphysical Themes 1274-1671 [2011], 23.5)
     A reaction: This seems to give a good explanation of why Aristotelianism plummeted to oblivion in the 17th C. Pasnau obviously wants to revive it, by drawing a sharp line between metaphysics and science. I doubt the line.
If crowds are things at all, they seem to be Substances, since they bear properties [Pasnau]
     Full Idea: Crowds seem to be the bearers of properties, and if they are things at all, then there is no place for them other than in the category of Substance.
     From: Robert Pasnau (Metaphysical Themes 1274-1671 [2011], 26.1)
     A reaction: It is tempting to say, based on Aristotle, that a substance is whatever 1) bears properties, and 2) endures in spite of change, but a crowd is a nice problem case, because it looks too disunited to be a 'substance'.
9. Objects / B. Unity of Objects / 2. Substance / c. Types of substance
Scholastics use 'substantia' for thick concrete entities, and for thin metaphysical ones [Pasnau]
     Full Idea: Scholastic texts are rife with different senses of 'substantia', using the term to refer, among other things, both to thick concrete entities and to thin metaphysical ones.
     From: Robert Pasnau (Metaphysical Themes 1274-1671 [2011], 06.1)
     A reaction: Pasnau introduces 'thin' and 'thick' substance for this reason. I may adopt this. Without distinctions between thin and thick concepts of things we can get very muddled. I like the word to label something which is an 'entity'.
9. Objects / B. Unity of Objects / 2. Substance / e. Substance critique
For corpuscularians, a substance is just its integral parts [Pasnau]
     Full Idea: According to strict corpuscularianism the only real constituents of a substance are its integral parts.
     From: Robert Pasnau (Metaphysical Themes 1274-1671 [2011], 26.1)
     A reaction: An understandable reaction to the emptiness of Aristotelian substantial forms in science. It seems to leave out the structural principles that distinguish one arrangement of parts from another. See Koslicki on this.
9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
If clay survives destruction of the statue, the statue wasn't a substance, but a mere accident [Pasnau]
     Full Idea: The unitarian view of substance says it cannot be divided. If the clay can survive the destruction of the statue, then that shows that the statue was not a substance at all, and that its shape (or whatever made it a statue) was merely a passing accident.
     From: Robert Pasnau (Metaphysical Themes 1274-1671 [2011], 25.3)
     A reaction: This seems to give the orthodox Aristotelian/Thomist reading, assuming that a substance only has one form, which unifies it. Since clay must have shape, and statues must have matter, I have never understood how there were two objects here.
