7938 | Relational properties are clearly not essential to substances [Macdonald,C] |
Full Idea: In statements attributing relational properties ('Felix is my favourite cat'), it seems clear that the property truly attributed to the substance is not essential to it. | |
From: Cynthia Macdonald (Varieties of Things [2005], Ch.3) | |
A reaction: A fairly obvious point, but an important one when mapping out (cautiously) what we actually mean by 'property'. However, maybe the relational property is essential: the ceiling is ('is' of predication!) above the room. |
7967 | Being taller is an external relation, but properties and substances have internal relations [Macdonald,C] |
Full Idea: The relation of being taller than is an external relation, since it relates two independent material substances, but the relation of instantiation or exemplification is internal, in that it relates a substance with a property. | |
From: Cynthia Macdonald (Varieties of Things [2005], Ch.6) | |
A reaction: An interesting revival of internal relations. To be plausible it would need clear notions of 'property' and 'substance'. We are getting a long way from physics, and I sense Ockham stropping his Razor. How do you individuate a 'relation'? |
