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

16597	Quantity is the capacity to be divided
	Full Idea: Quantity …is divisibility, or a capacity to be divided into parts.
	From: Kenelm Digby (Two treatises [1644], I.2.8), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 04.1
	A reaction: 'Quantity' is scholastic philosophy is a concept we no longer possess. Without quantity, a thing might potentially exist at a spaceless point. Quantity is what spreads things out. See Pasnau Ch. 4.

26. Natural Theory / A. Speculations on Nature / 7. Later Matter Theories / b. Corpuscles

16731	Colours arise from the rarity, density and mixture of matter
	Full Idea: The origin of all colours in bodies is plainly deduced out of the various degrees of rarity and density, variously mixed and compounded.
	From: Kenelm Digby (Two treatises [1644], I.29.4), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 22.5
	A reaction: We are still struggling with this question, though I think the picture is gradually become clear, once you get the hang of the brain. Easy! See Idea 17396.
