14. Science / D. Explanation / 2. Types of Explanation / g. Causal explanations

14367	An explanation is a causal graph [Woodward,J, by Strevens]
	Full Idea: On Woodward's manipulationist view, an explanation would take the form of a causal graph.
	From: report of James Woodward (Making Things Happen [2003]) by Michael Strevens - No Understanding without Explanation 1
	A reaction: The idea is that causation is all to do with how nature responds when you try to manipulate it. I'm certainly in favour of tying explanation closely to causation.

19. Language / C. Assigning Meanings / 10. Two-Dimensional Semantics

14894	Indexicals have a 'character' (the standing meaning), and a 'content' (truth-conditions for one context) [Kaplan, by Macià/Garcia-Carpentiro]
	Full Idea: Kaplan distinguished two different semantic features of indexical expressions: a 'character' that captures the standing meaning of the expression, and a 'content' that consists of their truth-conditional contribution in particular contexts.
	From: report of David Kaplan (Demonstratives [1989]) by Macià/Garcia-Carpentiro - Introduction to 'Two-Dimensional Semantics' 1
	A reaction: This seems so clearly right that there isn't much to dispute. You can't understand the word 'I' or 'now' if you don't understand both its general purpose, and what it is doing in a particular utterance. But will this generalise to other semantics?

14700	'Content' gives the standard modal profile, and 'character' gives rules for a context [Kaplan, by Schroeter]
	Full Idea: Kaplan sees two aspects of meaning, the 'content', reflecting a thing's modal profile, which is modelled by standard possible worlds semantics, and 'character', giving rules for different contexts. Proper names have constant character; indexicals vary.
	From: report of David Kaplan (Demonstratives [1989]) by Laura Schroeter - Two-Dimensional Semantics 1.1.1
	A reaction: This gives rise to 2-D matrices for representing meaning, and the possible worlds are used twice, for evaluating meaning and then for evaluating context of use. I've always been struck by the two-dimensional semantics of passwords.

20. Action / C. Motives for Action / 3. Acting on Reason / c. Reasons as causes

9284	Reasons are 'internal' if they give a person a motive to act, but 'external' otherwise [Williams,B]
	Full Idea: Someone has 'internal reasons' to act when the person has some motive which will be served or furthered by the action; if this turns out not to be so, the reason is false. Reasons are 'external' when there is no such condition.
	From: Bernard Williams (Internal and External Reasons [1980], p.101)
	A reaction: [compressed] An external example given is a family tradition of joining the army, if the person doesn't want to. Williams says (p.111) external reason statements are actually false, and a misapplication of the concept of a 'reason to act'. See Idea 8815.
