 By the constructive empiricist’s lights, distant macroscopic objects are observable, since if we were nearby we could see them. Paul Churchland (1985, 39–40) takes issue with the importance the constructive empiricist attaches to size, as opposed to spatiotemporal proximity. Churchland points out that it is just a contingent fact that humans have control over their spatiotemporal location, but not over their size. Churchland concludes that the distinction between things that are unobserved but observable, and things that are unobservable, “is only very feebly principled and is wholly inadequate to bear the great weight that van Fraassen puts on it” (Churchland 1985, 40).
