| 17678 | Universals are just the repeatable features of a world [Armstrong] |
| Full Idea: Universals can be brought into the spatio-temporal world, becoming simply the repeatable features of that world. | |
| From: David M. Armstrong (What is a Law of Nature? [1983], 06.2) | |
| A reaction: I wish Armstrong wouldn't use the word 'universal', which has so much historical baggage. The world obviously has repeatable features, but does that mean that our ontology must include things called 'features'? Hm. |
| 17669 | Realist regularity theories of laws need universals, to pick out the same phenomena [Armstrong] |
| Full Idea: A Realistic version of a Regularity theory of laws will have to postulate universals. How else will it be possible to say that the different instances of a certain uniformity are all instances of objectively the same phenomenon? | |
| From: David M. Armstrong (What is a Law of Nature? [1983], 02.4) | |
| A reaction: I disagree. We may (or may not) need properties, but they can be have a range. We just need stable language. We use one word 'red', even when the shade of redness varies. Non-realists presumably refer to sense-data. |
| 17677 | Past, present and future must be equally real if universals are instantiated [Armstrong] |
| Full Idea: Past, present and future I take to be all and equally real. A universal need not be instantiated now. | |
| From: David M. Armstrong (What is a Law of Nature? [1983], 06.2) | |
| A reaction: This is the price you must pay for saying that you only believe in universals which are instantiated. |
| 15442 | Universals are abstractions from their particular instances [Armstrong, by Lewis] |
| Full Idea: Armstrong takes universals generally, and structural universals along with the rest, to be abstractions from their particular instances. | |
| From: report of David M. Armstrong (What is a Law of Nature? [1983], p.83-4) by David Lewis - Against Structural Universals 'The pictorial' | |
| A reaction: To me, 'abstracted' implies a process of human psychology, a way of thinking about the instances. I don't see how there can be an 'abstracted' relation which is a part of the external world. That makes his laws of nature human creations. |
| 17686 | Universals are abstractions from states of affairs [Armstrong] |
| Full Idea: Universals are abstractions from states of affairs. | |
| From: David M. Armstrong (What is a Law of Nature? [1983], 7) | |
| A reaction: I'm getting confused about Armstrong's commitments. He bases his whole theory on the existence of universals (repeatable features), but now says those are 'abstracted' from something else. Abstracted by us? |
