4 ideas

1. Philosophy / C. History of Philosophy / 2. Ancient Philosophy / b. Pre-Socratic philosophy

21355	The Pre-Socratics are not simple naturalists, because they do not always 'leave the gods out' [Leroi]
	Full Idea: The problem with making naturalism the hallmark of Pre-Socratic thought ...is that they do not always 'leave the gods out'; the Divine can usually be found lurking somewhere is their cosmologies.
	From: Armand Marie LeRoi (The Lagoon: how Aristotle invented science [2014], 007)
	A reaction: An important observation. I've been guilty of this simplistic view. We tend to ignore the religious fragments, or we possess so little that we have no idea where religion figured in their accounts.

7. Existence / A. Nature of Existence / 6. Criterion for Existence

3534	To be is to have causal powers [Alexander,S]
	Full Idea: To be is to have causal powers.
	From: Samuel Alexander (works [1927], §4), quoted by Jaegwon Kim - Nonreductivist troubles with ment.causation
	A reaction: This is sometimes called Alexander's Principle. It is first found in Plato, and is popular with physicalists, but there are problem cases... A thing needs to exist in order to have causal powers. To exist is more than to be perceived.

17. Mind and Body / A. Mind-Body Dualism / 6. Epiphenomenalism

3398	Epiphenomenalism makes the mind totally pointless [Alexander,S]
	Full Idea: Epiphenomenalism supposes something to exist in nature which has nothing to do and no purpose to serve.
	From: Samuel Alexander (works [1927]), quoted by Jaegwon Kim - Philosophy of Mind p.129
	A reaction: An objection, but not, I think, a strong one. The fact, for example, that sweat is shiny is the result of good evolutionary reasons, but I cannot think of any purpose which it serves. All events which are purposeful are likely to have side-effects.

27. Natural Reality / G. Biology / 3. Evolution

15961	I don't see how mere moving matter can lead to the bodies of men and animals, and especially their seeds [Boyle]
	Full Idea: I confess I cannot well conceive how from matter, barely put into motion and left to itself, there could emerge such curious fabricks as the bodies of men and perfect animals, and more admirably contrived parcels of matter, as seeds of living creatures.
	From: Robert Boyle (The Sceptical Chemist [1661], p.569), quoted by Peter Alexander - Ideas, Qualities and Corpuscles
	A reaction: This is here to show that one of the most brilliant intellects of the seventeenth century thought carefully about this question and couldn't answer it. Natural selection really was a rather clever idea.
