9. Objects / A. Existence of Objects / 1. Physical Objects

6473	Physical things are series of appearances whose matter obeys physical laws [Russell]
	Full Idea: We may lay down the following definition: Physical things are those series of appearances whose matter obeys the laws of physics.
	From: Bertrand Russell (The Relation of Sense-Data to Physics [1914], §XI)
	A reaction: We will then have to define the laws of physic without making any reference to 'physical things'. There is an obvious suspicion of circularity somewhere here. I find it very odd to define objects just in terms of their appearances.
