Single Idea 16776

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

Full Idea

Substance an ens per se. No part of a substance is an ens per se when it is part of a substance, because then it would be a particular thing, and one substance would be a particular thing from many things, which does not seem to be true.


'ens per se' (Lat) is an 'entity in itself'

Gist of Idea

Substance is an intrinsic thing, so parts of substances can't also be intrinsic things


John Duns Scotus (In Praed. [1300], 15.1), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 26.1

A Reaction

The tricky bit is 'when it is a part of a substance', meaning a substance must cease to be a substance when it is subsumed into some greater substance. Maybe. Drops of water? Molecules? Bricks? Cells?
