Unity Relations


In this seminar we will focus on unity relations. By ‘unity relations’, we mean all those relations that have the crucial role of (i) making from many things one, or (ii) making diverse things that are not strictly speaking identical count as the same in a context or under a given respect. The relation playing role (i) is involved in familiar cases such as a human body or an abbey, i.e. one thing that somehow emerges from many. The phenomenon described in (ii) might sound exotic instead (how can two or more things somehow be the same?), but it is a commitment of some well-established metaphysical views such as perdurantism and counterpart theory.
