9. Objects / F. Identity among Objects / 7. Indiscernible Objects

5055	No two things are totally identical [Leibniz]
	Full Idea: By virtue of insensible variations, two individual things can never be perfectly alike.
	From: Gottfried Leibniz (New Essays on Human Understanding [1704], Pref)
	A reaction: This sounds a bit like the 'discernibility of non-identicals', except that he says that the differences may not be 'sensible'. He has to be talking of physical things, since I presume that, say, the symmetry of two circles is perfectly identical.
