 A fair portion of the constructive empiricist’s account of scientific explanation is thus devoted to an explication of the contextual dependence of explanation. Among other reasons given in favor of that contextual dependence, van Fraassen points out that explanations are typically causal in character—they attempt to situate the event-to-be-explained in the “causal net” postulated by the scientific theory. Which events in that net are picked out as “the” cause(s) of some event-to-be-explained depend upon the interests of the individuals asking the explanatory question (1980, 124–126).
