A Reaction

I take the 'every respect' to include the avoidance of ambiguity, and some sort of perspicacious reference for the terms. I wish philosophers would focus on the thoughts in their subject, and not nit-pick about the sentences. Does he mean 'utterances'?

A sentence is only a thought if it is complete, and has a time-specification [Frege]
A proposition is a unity, and analysis destroys it [Russell]
Russell said the proposition must explain its own unity - or else objective truth is impossible [Russell, by Davidson]
Hegelians say propositions defy analysis, but Moore says they can be broken down [Moore,GE, by Monk]
A proposition ingredient is 'essential' if changing it would change the truth-value [Fine,K]
Unity of the proposition questions: what unites them? can the same constituents make different ones? [Merricks]
We want to explain not just what unites the constituents, but what unites them into a proposition [Merricks]
