11. Knowledge Aims / B. Certain Knowledge / 2. Common Sense Certainty

6349	I can prove a hand exists, by holding one up, pointing to it, and saying 'here is one hand' [Moore,GE]
	Full Idea: I can prove now that two human hands exist. How? By holding up my two hands, and saying, as I make a certain gesture with the right hand, 'Here is one hand', and adding, as I gesture with the left, 'and here is another'.
	From: G.E. Moore (Proof of an External World [1939], p.1)
	A reaction: The words need to be spoken, presumably, so that what he is doing fits into the linguistic conventions of what will normally be accepted as a proof. In fact, just holding the hand up seems enough. The proof begs the question of virtual reality.

13. Knowledge Criteria / C. External Justification / 6. Contextual Justification / a. Contextualism

19508	Contextualism needs a semantics for knowledge sentences that are partly indexical [Schiffer,S]
	Full Idea: Contextualist semantics must capture the 'indexical' nature of knowledge claims, the fact that different utterances of a knowledge sentence with no apparent indexical terms can express different propositions.
	From: Stephen Schiffer (Contextualist Solutions to Scepticism [1996], p.325), quoted by Keith DeRose - The Case for Contextualism 1.5
	A reaction: Schiffer tries to show that this is too difficult, and DeRose defends contextualism against the charge.

19509	The indexical aspect of contextual knowledge might be hidden, or it might be in what 'know' means [Schiffer,S]
	Full Idea: One might have a 'hidden-indexical' theory of knowledge sentences: they contain constituents that are not the semantic values of any terms; ...or 'to know' itself might be indexical, as in 'I know[easy] I have hands' or 'I know[tough] I have hands'.
	From: Stephen Schiffer (Contextualist Solutions to Scepticism [1996], p.326-7), quoted by Keith DeRose - The Case for Contextualism 1.5
	A reaction: [very compressed] Given the choice, I would have thought it was in 'know', since to say 'either you know p or you don't' sounds silly to me.

24. Political Theory / D. Ideologies / 10. Theocracy

7825	The politics of Leibniz was the reunification of Christianity [Stewart,M]
	Full Idea: The politics of Leibniz may be summed up in one word: theocracy. The specific agenda motivating much of his work was to reunite the Protestant and Catholic churches
	From: Matthew Stewart (The Courtier and the Heretic [2007], Ch. 5)
	A reaction: This would be a typical project for a rationalist philosopher, who thinks that good reasoning will gradually converge on the one truth.
