Single Idea 15560

[filed under theme 10. Modality / B. Possibility / 7. Chance ]

Full Idea

I think we are right to explain chance events, yet we are right also to deny that we can ever explain why a chance process yields one outcome rather than another. We cannot explain why one event happened rather than the other.

Gist of Idea

We can explain a chance event, but can never show why some other outcome did not occur

Source

David Lewis (Causal Explanation [1986], VI)

Book Ref

Lewis,David: 'Philosophical Papers Vol.2' [OUP 1986], p.230


A Reaction

This misses out an investigation which slowly reveals that a 'chance' event wasn't so chancey after all. Failure to explain confirms chance, so the judgement of chance shouldn't block attempts to explain.


The 12 ideas from 'Causal Explanation'

Lewis endorses the thesis that all explanation of singular events is causal explanation [Lewis, by Psillos]
Ways of carving causes may be natural, but never 'right' [Lewis]
We only pick 'the' cause for the purposes of some particular enquiry. [Lewis]
Causal dependence is counterfactual dependence between events [Lewis]
To explain an event is to provide some information about its causal history [Lewis]
A disposition needs a causal basis, a property in a certain causal role. Could the disposition be the property? [Lewis]
Explaining match lighting in general is like explaining one lighting of a match [Lewis]
Science may well pursue generalised explanation, rather than laws [Lewis]
A good explanation is supposed to show that the event had to happen [Lewis]
Does a good explanation produce understanding? That claim is just empty [Lewis]
Verisimilitude has proved hard to analyse, and seems to have several components [Lewis]
We can explain a chance event, but can never show why some other outcome did not occur [Lewis]
