Place, U. T. (1997e). On the nature of conditionals and their truthmakers. Acta Analytica, 12(18), 73-88.
[Abstract]Standard propositional and predicate logic fails both as a model for natural language and, since it cannot handle causation, as a language for science. The failure to handle causation stems from a misconstrual of the causal conditional as a relation between the truth of two propositions (If p, then q). What the causal conditional in fact specifies is a 'relation' between the possible existence or non-existence of two situations made true by the existence of the dispositional properties of the concrete particulars involved.

[Abstract]A distinction is drawn between de dicto modality which is a matter of which propositions can, cannot and must be true, given the laws of logic, and de re modality which is a matter of which situations (events or states of affairs) can, cannot and must exist, given the laws of nature. It is argued that Kripke's de re modality, defined in terms of what is true in some possible world, no possible world and all possible worlds, is an unsatisfactory amalgam of the two.
