6 ideas

27. Natural Reality / A. Classical Physics / 1. Mechanics / a. Explaining movement

399	If the more you raise some earth the faster it moves, why does the whole earth not move? [Aristotle]
	Full Idea: If you raise some earth and release it, it moves and won't stay put, and the more you raise it the faster it moves, so why does the whole earth not move?
	From: Aristotle (On the Heavens [c.336 BCE], 294a12)

27. Natural Reality / C. Space / 1. Void

20918	Void is a kind of place, so it can't explain place [Aristotle]
	Full Idea: It is absurd to explain place by the void, as though this latter were not itself some kind of place.
	From: Aristotle (On the Heavens [c.336 BCE], 309b24)
	A reaction: Presumably this is aimed at Democritus.

27. Natural Reality / E. Cosmology / 1. Cosmology

402	The Earth must be spherical, because it casts a convex shadow on the moon [Aristotle]
	Full Idea: A lunar eclipse always has a convex dividing line, so, if it is eclipsed by the interposition of the earth, the circumference of the earth, being spherical, is responsible for the shape.
	From: Aristotle (On the Heavens [c.336 BCE], 297b29)

403	The earth must be round and of limited size, because moving north or south makes different stars visible [Aristotle]
	Full Idea: Clearly the earth is round and not of great size, because when we move north or south we find that very different stars are visible.
	From: Aristotle (On the Heavens [c.336 BCE], 297b30)

27. Natural Reality / E. Cosmology / 3. The Beginning

1498	Everyone agrees that the world had a beginning, but thinkers disagree over whether it will end [Aristotle]
	Full Idea: All thinkers agree that the world had a beginning, but some claim that, having come into existence, it is everlasting.
	From: Aristotle (On the Heavens [c.336 BCE], 279b12)

27. Natural Reality / E. Cosmology / 10. Multiverse

395	It seems possible that there exists a limited number of other worlds apart from this one [Aristotle]
	Full Idea: One might indeed be puzzled whether, just as the world about us exists, nothing prevents there being others as well, certainly more than one, though not an unlimited number
	From: Aristotle (On the Heavens [c.336 BCE], 274a26)
