Single Idea 14732

[filed under theme 9. Objects / A. Existence of Objects / 1. Physical Objects ]

Full Idea

The physical object, as inferred from perception, is a group of events arranged about a centre.

Gist of Idea

A perceived physical object is events grouped around a centre

Source

Bertrand Russell (The Analysis of Matter [1927], 23)

Book Ref

Russell,Bertrand: 'The Analysis of Matter' [Routledge 1992], p.244


A Reaction

At least I like the active aspect of this definition. You then have to explain what an event is, without mentioning objects. You'd better no mention properties either, since they will probably depend on the dreaded objects.
