9. Objects / B. Unity of Objects / 2. Substance / d. Substance defined

22628	Substance has to exist, with no intrinsic qualities or relations [McTaggart]
	Full Idea: Something must exist, then, and have qualities, without being itself either a quality or a relation. And this is Substance.
	From: J.M.E. McTaggart (The Nature of Existence vol.1 [1921], §67), quoted by R.D. Ingthorsson - A Powerful Particulars View of Causation 7.2
	A reaction: Ingthorsson quotes this as 'the most extreme analytic view', which is a long way from the Aristotelian view. This is the implausible bare substrate.

9. Objects / B. Unity of Objects / 3. Unity Problems / e. Vague objects

9602	Common sense and classical logic are often simultaneously abandoned in debates on vagueness [Williamson]
	Full Idea: The constraints of common sense and classical logic are often simultaneously abandoned in debates on vagueness.
	From: Timothy Williamson (The Philosophy of Philosophy [2007], After)
	A reaction: Wiliamson has described himself (in my hearing) as a 'rottweiller realist', but presumably the problem of vagueness interests a lot of people precisely because it pushes us away from common sense and classical logic.
