Van InWagen

Mereological essentialism: no object can lose or gain parts. In other words,

ME For any t, t


, if x is part of y at t, and y exists at t


, then x is part of y at t



4. Van Inwagen's answer to the Special Composition Question

The xs compose something iff the activity of the xs constitutes a life, or

there is only one of the xs.

What is a life? A certain kind of self-maintaining event, that is `reasonably well-

individuated' and `jealous' (it never happens that the activity of some things

constitutes two different lives).

A consequence of this view: there are no tables or computers or statues or lumps

of clay or ships or grains of sand.... For surely if there was such a things as a

table, etc., it would have to be composed by some things whose activity did not

constitute a life (and which were more than one in number).
