Full Idea

If all there are corpuscles of various shapes and sizes, variously arranged, it is not easy to see how we might draw the boundary lines, at any given moment, between one substance and another.

Gist of Idea

If there are just arrangements of corpuscles, where are the boundaries between substances?

A Reaction

We still have precisely that problem, and it leads to the nihilism about ordinary objects found in Unger, Van Inwagen and Merricks. I have so far found modern defences of ordinary objects unpersuasive.
