Abstract

The paper is a detailed reconstruction of Bernard Bolzano’s account of merely possible objects. According to Bolzano, there are some objects which are merely possible. They are neither denizens of space and time nor members of the causal order, but they could have been so. Examples are merely possible persons, mountains etc., objects which are neither actual nor persons or mountains, but which could have been both. Bolzano’s views are contrasted with the theory of Alexius Meinong, and it is shown that they have a modern counterpart in the accounts of merely possible objects that were developed by Bernard Linsky & Ed Zalta, and by Timothy Williamson
