4 ideas

19. Language / A. Nature of Meaning / 1. Meaning

19087	The meaning or purport of a symbol is all the rational conduct it would lead to [Peirce]
	Full Idea: The entire intellectual purport of any symbol consists in the total of all modes of rational conduct which, conditionally upon all the possible different circumstances and desires, would ensue upon the acceptance of the symbol.
	From: Charles Sanders Peirce (Issues of Pragmaticism [1905], EP ii.246), quoted by Danielle Macbeth - Pragmatism and Objective Truth p.169 n1
	A reaction: Macbeth says pragmatism is founded on this theory of meaning, rather than on a theory of truth. I don't see why the causes of a symbol shouldn't be as much a part of its meaning as the consequences are.

23. Ethics / B. Contract Ethics / 8. Contract Strategies

22725	When players don't meet again, defection is the best strategy [Axelrod]
	Full Idea: When players will never meet again, the strategy of defection is the only stable strategy.
	From: Robert Axelrod (The Evolution of Co-Operation [1984], 5)
	A reaction: This gives good grounds for any community's mistrust of transient strangers, such as tourists. And yet any sensible tourist will want communities to trust tourists, and will therefore behave in a reliable way.

22724	Good strategies avoid conflict, respond to hostility, forgive, and are clear [Axelrod]
	Full Idea: Successful game strategies avoid unnecessary conflict, are provoked by an uncalled for defection, forgive after a provocation, and behave clearly so the other player can adapt.
	From: Robert Axelrod (The Evolution of Co-Operation [1984], 1)
	A reaction: [compressed] Exactly what you would expect from a nice but successful school teacher. The strategies for success in these games is the same as the rules for educating a person into cooperative behaviour. TIT FOR TAT does all these.

27. Natural Reality / D. Time / 1. Nature of Time / e. Eventless time

16697	Time is independent of motion, because God could stop everything for a short or long time [Crathorn, by Pasnau]
	Full Idea: Suppose God annihilates everything, and then creates something new. The vacant interval could last a shorter or longer time, so there are facts about time independent of facts about motion.
	From: report of William Crathorn (Sentences [1335], I.16, concl.2) by Robert Pasnau - Metaphysical Themes 1274-1671 18.2
	A reaction: Not very persuasive if God is in some way 'timeless'. Crathorn would have loved Shoemaker's argument, where motionless time is the best explanation, rather than a possible explanation.
