Bolzanos Konzeption bloß möglicher Gegenstände

Abstract

Abstract In Section 1, the author argues that Bolzano does not have a Meinongian view of merely possible objects, not even in the context of his theory of intentionality. In section 2, it is argued that Williamson’s necessitist conception, according to which there is a merely possible golden mountain, was not anticipated by Bolzano. An eternalist reconstruction is rejected as well. The argument takes recourse to Bolzano’s semantics of temporal statements, which also underlies his argument for the eternity of substances and makes it plausible to assume that Bolzano had a perdurantist view, according to which there are merely possible objects just in case there are actual objects whose generation is to be metaphysically explained, in terms of grounding, by recourse to a merely possible object’s being replaced by an actual object. Furthermore, it is argued that merely possible objects à la Bolzano are not substances, in his narrow sense of the term, and that his case for such objects in connection with his view of generation is less than convincing. However, section 3 argues that Bolzano’s conception combines with his view of substance to yield an interesting perdurantist conception of personal identity.
