 Identity and Unity

Show Summary Details


The relationship between the notion of an object and the notion of unity is discussed. It is argued that we should acknowledge the possible existence of entities belonging to certain ontological categories whose members lack either the determinate identity or the determinate unity—and hence countability—that are characteristic of objects properly so‐called. Such categories, it is suggested, are needed, amongst other things, to make sense of some of the theoretical entities postulated by modern quantum physics. In this connection, a famous argument by Gareth Evans against ‘vague’ identity is countered.

Keywords: countability; determinacy; Gareth Evans; identity; objects; ontological categories; quantum physics; unity; vague identity; vagueness
