Single Idea 19347

[catalogued under 9. Objects / B. Unity of Objects / 2. Substance / d. Substance defined]

Full Idea

For individuation, substance needs three properties: independence, to separate it from other things; unity, to call it one thing, rather than an aggregate; and permanence or stability over time. Its other role is as subject for predicates.

Gist of Idea

Substance needs independence, unity, and stability (for individuation); also it is a subject, for predicates

A Reaction

Perkins is describing the Aristotelian view, which is taken up by Leibniz. 'Substance' is not a controversial idea, if we see that it only means that the world is full of 'things'. It is an unusual philosopher wholly totally denies that.
