9. Objects / D. Essence of Objects / 14. Knowledge of Essences

11966	If there are essential properties, how do you find out what they are? [Chisholm]
	Full Idea: It seems to me that if Adam does have essential properties, there is no procedure at all for finding out what they are.
	From: Roderick Chisholm (Identity through Possible Worlds [1967], p.85)
	A reaction: My tentative suggestion is that the essential properties are those which explain the nature, power, function and role of Adam in the 'actual' world. Whatever possibilities he acquires, he had better retain the capacity to be the First Man.

10. Modality / E. Possible worlds / 3. Transworld Objects / a. Transworld identity

11965	Could possible Adam gradually transform into Noah, and vice versa? [Chisholm]
	Full Idea: If Adam lived for 931 years in a possible world, instead of his actual 930 years, ..then Adam and Noah could gradually exchange their ages and other properties...and we could trace Adam in a world back to the actual Noah, and vice versa.
	From: Roderick Chisholm (Identity through Possible Worlds [1967], p.81-2)
	A reaction: [very compressed] Chisholm was one of the first to raise this problem for possible worlds, though it had been Quine's objection to modal logic all along. Only Adam having essential properties seems to stop this slippery slope, says Chisholm.

16. Persons / C. Self-Awareness / 3. Limits of Introspection

3102	Why don't we experience or remember going to sleep at night? [Magee]
	Full Idea: As a child it was incomprehensible to me that I did not experience going to sleep, and never remembered it. When my sister said 'Nobody remembers that', I just thought 'How does she know?'
	From: Bryan Magee (Confessions of a Philosopher [1997], Ch.I)
	A reaction: This is actually evidence for something - that we do not have some sort of personal identity which is separate from consciousness, so that "I am conscious" would literally mean that an item has a property, which it can lose.

26. Natural Theory / C. Causation / 4. Naturalised causation

8326	Science has shown that causal relations are just transfers of energy or momentum [Fair, by Sosa/Tooley]
	Full Idea: Basic causal relations can, as a consequence of our scientific knowledge, be identified with certain physicalistic [sic] relations between objects that can be characterized in terms of transference of either energy or momentum between objects.
	From: report of David Fair (Causation and the Flow of Energy [1979]) by E Sosa / M Tooley - Introduction to 'Causation' §1
	A reaction: Presumably a transfer of momentum is a transfer of energy. If only anyone had the foggiest idea what energy actually is, we'd be doing well. What is energy made of? 'No identity without substance', I say. I like Fair's idea.

10379	Fair shifted his view to talk of counterfactuals about energy flow [Fair, by Schaffer,J]
	Full Idea: Fair, who originated the energy flow view of causation, moved to a view that understands connection in terms of counterfactuals about energy flow.
	From: report of David Fair (Causation and the Flow of Energy [1979]) by Jonathan Schaffer - The Metaphysics of Causation 2.1.2
	A reaction: David Fair was a pupil of David Lewis, the king of the counterfactual view. To me that sounds like a disappointing move, but it is hard to think that a mere flow of energy through space would amount to causation. Cause must work back from an effect.
