| 8299 | Abstractions are non-spatial, or dependent, or derived from concepts [Lowe] |
| Full Idea: There are three conceptions of abstractness: 1) non-spatial entities, the opposite of 'concrete' (e.g. numbers and universals); 2) an entity logically incapable of a separate existence (e.g. an apple's colour); 3) Fregean abstractions from concepts. | |
| From: E.J. Lowe (The Possibility of Metaphysics [1998], 10.1) | |
| A reaction: [Lowe p.218 explains the third one] Lowe rejects the third one, and it is a moot point whether the second one could actually be classed as an entity (do they have identity-conditions?), so the big issue is the first one. |
| 4237 | Concrete and abstract objects are distinct because the former have causal powers and relations [Lowe] |
| Full Idea: Concrete objects possess causal powers and relations, but abstract objects are incapable of having causal powers or relations. | |
| From: E.J. Lowe (A Survey of Metaphysics [2002], p.368) | |
| A reaction: Is this an observation or a definition? One might claim that an abstraction (such as a political ideal) can acquire causal power through a conscious mnd. |
| 4238 | The centre of mass of the solar system is a non-causal abstract object, despite having a location [Lowe] |
| Full Idea: The centre of mass of the solar system seems to lack causal powers, and so is an abstract object, even though it has a location and movement. | |
| From: E.J. Lowe (A Survey of Metaphysics [2002], p.368) | |
| A reaction: Nice example, with rich ramifications. Abstraction is deeply tied into our understanding of the physical world, and our concept of identity. |
| 8306 | You can think of a direction without a line, but a direction existing with no lines is inconceivable [Lowe] |
| Full Idea: Although one can separate 'in thought' a direction from any line of which it is the direction, one cannot conceive of a direction existing in the absence of any line possessing that direction. | |
| From: E.J. Lowe (The Possibility of Metaphysics [1998], 10.3) | |
| A reaction: Intriguing. If I ask you to imagine a line going in a certain direction, don't you need the direction before you can think of the line? 'That line is going in the wrong direction'. Maybe abstract ideas only exist 'in thought'. Lowe is a realist here. |
