Extract

At the outset of his instructive and thought-provoking paper, ‘The Nature of Possibility,’ Professor David Armstrong gives a succinct description, in itself almost complete, of his ‘combinatorial theory’ of possibility. He says: ‘Such a view traces the very idea of possibility to the idea of the combinations - allthe combinations which respect certain simple form- of given, actual elements’ (575). We can perhaps start a bit further back than this. In explaining the idea of a ‘possible world,’ some philosophers begin with the idea of ‘things being a certain way’ or ‘the way things are.’ From this idea a leap is made to ‘things might have been a certain other way’ or ‘ways things could have been.’ And here we already have possible worlds, or so some philosophers assure us: David Lewis, for example, says his talk of possible worlds is nothing but a ‘permissible paraphrase’ of this familiar and innocent-sounding locution, ‘ways things could have been.'

6 This makes one wonder what ‘existence’ exactly could mean for universals.

7 Notice an interesting asymmetry: If a does not have F, there is no world here. For a's not having F (or a's having not-f) is not a molecular state of affairs. This would mean, I assume, the following must hold: every simple individual must have at least one simple property.

13 I am not even sure this is true. I am not sure that within Armstrong's actualist scheme there can be a true reading of statements of the form ‘There is a fictional world w such that …’.

14 One possible conclusion to draw, therefore, is that we should give up talk of possible worlds to explain modalities.
