5 ideas

14. Science / C. Induction / 1. Induction

22200	If you eliminate the impossible, the truth will remain, even if it is weird [Conan Doyle]
	Full Idea: When you have eliminated the impossible, whatever remains, however improbable, must be the truth.
	From: Arthur Conan Doyle (The Sign of Four [1890], Ch. 6)
	A reaction: A beautiful statement, by Sherlock Holmes, of Eliminative Induction. It is obviously not true, of course. Many options may still face you after you have eliminated what is actually impossible.

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.

23. Ethics / D. Deontological Ethics / 3. Universalisability

21051	Check your rationality by thinking of your opinion pronounced by the supreme court [Rawls]
	Full Idea: To check whether we are following public reason we might ask: how would our argument strike us presented in the form of a supreme court opinion?
	From: John Rawls (Political Liberalism [1993], p.254), quoted by Michael J. Sandel - Justice: What's the right thing to do? 10
	A reaction: A very nice practical implementation of Kantian universalisability. How would your opinion sound if it were written into a constitution?

24. Political Theory / B. Nature of a State / 2. State Legitimacy / c. Social contract

21119	Power is only legitimate if it is reasonable for free equal citizens to endorse the constitution [Rawls]
	Full Idea: Exercise of political power is fully proper only when it is exercised in accordance with a constitution the essentials of which all citizens as free and equal may reasonably be expected to endorse in light of principles and ideals acceptable to reason.
	From: John Rawls (Political Liberalism [1993], p.217), quoted by Andrew Shorten - Contemporary Political Theory 02
	A reaction: This is not the actual endorsement of Rousseau, or the tacit endorsement of Locke (by living there), but adds a Kantian appeal to a rational consensus, on which rational people should converge. Very Enlightenment. 'Hypothetical consent'.
