3. Truth / H. Deflationary Truth / 1. Redundant Truth
3750 "It is true that x" means no more than x [Ramsey]
     Full Idea: It is evident that "It is true that Caesar was murdered" means no more than that Caesar was murdered.
     From: Frank P. Ramsey (Facts and Propositions [1927])
     A reaction: At the very least, saying it is true adds emphasis. One sentence is about Caesar, the other about a proposal concerning Caesar, so they can't quite be the same. Note Frege's priority in making this suggestion.
4. Formal Logic / D. Modal Logic ML / 4. Alethic Modal Logic
16456 For modality Lewis rejected boxes and diamonds, preferring worlds, and an index for the actual one [Lewis, by Stalnaker]
     Full Idea: Lewis was suspicious of boxes and diamonds as regimenting ordinary modal thought, …preferring a first-order extensional theory including possible worlds in its domain and an indexical singular term for the actual world.
     From: report of David Lewis (Anselm and Actuality [1970]) by Robert C. Stalnaker - Mere Possibilities 3.8
7. Existence / B. Change in Existence / 1. Nature of Change
15541 Maybe particles are unchanging, and intrinsic change in things is their rearrangement [Lowe, by Lewis]
     Full Idea: Lowe's solution the 'temporary intrinsics' problem is that particles have no temporary intrinsic properties; they may be safely supposed to endure, and large things consist of those enduring particles, undergoing rearrangement but no intrinsic change.
     From: report of E.J. Lowe (Lewis on Perdurance versus Endurance [1987]) by David Lewis - Rearrangement of Particles II
     A reaction: A mere rearrangement of particles doesn't sound the same as a change in properties, which must involve causal powers in some way.
19. Language / A. Nature of Meaning / 7. Meaning Holism / c. Meaning by Role
18818 Sentence meaning is given by the actions to which it would lead [Ramsey]
     Full Idea: The meaning of a sentence is to be defined by reference to the actions to which asserting it would lead.
     From: Frank P. Ramsey (Facts and Propositions [1927], p.51), quoted by Ian Rumfitt - The Boundary Stones of Thought
     A reaction: I find this idea quite bizarre. Most sentences have no connection to any action or behavior at all. Do we have to ingeniously contrive some possible action? That is the worst sort of behaviourism. See context - Ramsey wasn't stupid!
