7. Existence / A. Nature of Existence / 3. Being / e. Being and nothing

21982	I only wish I had such eyes as to see Nobody! It's as much as I can do to see real people. [Carroll,L]
	Full Idea: "I see nobody on the road," said Alice. - "I only wish I had such eyes," the King remarked. ..."To be able to see Nobody! ...Why, it's as much as I can do to see real people."
	From: Lewis Carroll (C.Dodgson) (Through the Looking Glass [1886], p.189), quoted by A.W. Moore - The Evolution of Modern Metaphysics 07.7
	A reaction: [Moore quotes this, inevitably, in a chapter on Hegel] This may be a better candidate for the birth of philosophy of language than Frege's Groundwork.

7. Existence / E. Categories / 5. Category Anti-Realism

16608	Ockham was an anti-realist about the categories [William of Ockham, by Pasnau]
	Full Idea: Ockham is the scholastic paradigm of anti-realism with respect to the categories.
	From: report of William of Ockham (Summula philosophiae naturalis [1320]) by Robert Pasnau - Metaphysical Themes 1274-1671 05.3
	A reaction: These are the ten categories mentioned in Aristotle's book 'Categories'.

9. Objects / C. Structure of Objects / 4. Quantity of an Object

16599	Ockham says matter must be extended, so we don't need Quantity [William of Ockham, by Pasnau]
	Full Idea: Ockham regards Quantity as an entirely superfluous ontological category, …because matter is intrinsically extended.
	From: report of William of Ockham (Summula philosophiae naturalis [1320]) by Robert Pasnau - Metaphysical Themes 1274-1671 04.4

16681	Matter gets its quantity from condensation and rarefaction, which is just local motion [William of Ockham]
	Full Idea: Matter is made to have a greater or lesser quantity not through its receiving any absolute accident, but through condensation and rarefaction alone. Parts come more or less close together, which can happen with local motion.
	From: William of Ockham (Summula philosophiae naturalis [1320], I.13), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 15.1
	A reaction: This is Ockham at his most modern, rejecting the odd idea of Quantity in favour of a modern corpuscular view of the mere motions of matter.

28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof

2116	The concept of an existing thing must contain more than the concept of a non-existing thing [Leibniz]

	From: Gottfried Leibniz (On the Principles of Indiscernibles [1696], p.134)
