Substance (n.) changing under you no more makes two persons than wearing other clothes today makes two men.
Substance (n.) is something of which we have no idea what it is, only a confused, obscure idea of what it does.
Substance (n.) was the word invented to hold up accidents, once these were imagined as real beings needing something to inhere in.
Substance (n.) has no abstract names, and that silence is mankind's confession that it has no idea of the real essences of substances.
Substance (n.) and inherence, put into plain English, are "under-propping" and "sticking on" — and the translation shows how much they really explain.
Substance (n.) is a word for something-I-know-not-what: we cannot imagine qualities floating free, so we suppose a support beneath them we have no idea of.
Substance (n.) gives us ideas that are false in the greatest part, if not all, once we take them to show the real essence on which all properties depend.
Substance (n.) can belong to two persons in turn: what was part of me a moment ago may soon become a real part of someone else.

Substance (n.) of every kind has something in it that manifestly baffles our understanding — so incomprehensibility is no argument against existence.
Substance (n.) affords so few certain general propositions, and of so little moment, that our certain general knowledge of it may justly be looked on as almost none at all.

Substance (n.) in general propositions is for the most part trifling when those propositions are certain, and uncertain when they are instructive.
