Single Idea 15876

[filed under theme 26. Natural Theory / D. Laws of Nature / 5. Laws from Universals ]

Full Idea

The idea of the Dretske-Armstrong-Tooley view is very simple: the laws of nature relate properties to properties.

Gist of Idea

Maybe laws of nature are just relations between properties?

A Reaction

Presumably the relations are necessary ones. I don't see why we need to mention these wretched 'universals' in order to expound this theory. It sounds much more plausible if you just say a property is defined by the way it relates to other properties.


The 13 ideas with the same theme [laws seen as necessary relations between universals]:

In causal laws, 'events' must recur, so they have to be universals, not particulars [Russell]
Rather than take necessitation between universals as primitive, just make laws primitive [Maudlin on Armstrong]
Armstrong has an unclear notion of contingent necessitation, which can't necessitate anything [Bird on Armstrong]
The laws of nature link properties with properties [Armstrong]
Maybe laws of nature are just relations between properties? [Harré]
We might say laws are necessary by combining causal properties with Armstrong-Dretske-Tooley laws [Shoemaker]
Originally Humeans based lawlike statements on pure qualities, without particulars [Harré/Madden]
Individuals enter into laws only through their general qualities and relations [McMichael]
Laws of nature are necessary relations between universal properties, rather than about particulars [Mumford]
If laws can be uninstantiated, this favours the view of them as connecting universals [Mumford]
Laws cannot offer unified explanations if they don't involve universals [Bird]
If the universals for laws must be instantiated, a vanishing particular could destroy a law [Bird]
The view that laws are grounded in substance plus external necessity doesn't suit dispositionalism [Vetter]
