Single Idea 14376

[filed under theme 10. Modality / B. Possibility / 1. Possibility ]

Full Idea

A non-actual state of affairs in possible if there actually was a substance capable of initiating a causal chain, perhaps non-deterministic, that could lead to the state of affairs that we claim is possible.

Gist of Idea

States of affairs are only possible if some substance could initiate a causal chain to get there

A Reaction

[He is quoting A.R. Pruss 2002] That seems exactly right. Of course the initial substance(s) might create a further substance, such as a transuranic element, which then produces the state of affairs. I favour this strongly actualist view.


The 13 ideas from 'A Powers Theory of Modality'

Unlike correspondence, truthmaking can be one truth to many truthmakers, or vice versa [Jacobs]
We can base counterfactuals on powers, not possible worlds, and hence define necessity [Jacobs]
Concrete worlds, unlike fictions, at least offer evidence of how the actual world could be [Jacobs]
If some book described a possibe life for you, that isn't what makes such a life possible [Jacobs]
Possible worlds are just not suitable truthmakers for modality [Jacobs]
All modality is in the properties and relations of the actual world [Jacobs]
If structures result from intrinsic natures of properties, the 'relations' between them can drop out [Jacobs]
Powers come from concrete particulars, not from the laws of nature [Jacobs]
States of affairs are only possible if some substance could initiate a causal chain to get there [Jacobs]
Possibilities are manifestations of some power, and impossibilies rest on no powers [Jacobs]
Science aims at identifying the structure and nature of the powers that exist [Jacobs]
Possible worlds semantics gives little insight into modality [Jacobs]
Counterfactuals invite us to consider the powers picked out by the antecedent [Jacobs]
