I’m also not clear on how broad “the terms you describe in Logical Pinpointing, Causal Reference, and Mixed Reference” are; he may think that he’s sketched meaningfulness criteria somewhere in those articles that are more inclusive than “The Great Reductionist Project” itself allows.
I think that was fairly clear. Each of those articles is explicitly about a form of reference sentences can have: logical, physical, or logicophysical, and his statement of the GRT was just that all meaningful (or in your reading, true) things can be expressed in these ways.
But it occurs to me that we can file something away, and tomorrow I’m going to read over your last three or four replies and think about the GRTt whether or not it’s EY’s view. That is, we can agree that the GRTm view is not a tenable thesis as we understand it.
One possible source of confusion: What is the meaning of the qualifier “physical”? “Physical,” “causal,” “verifiable,” and “taboo-able/analyzable” all have different senses, and it’s possible that for some of them Eliezer is more willing to allow meaningful falsehoods than for others.
Yeah. I’ll re-read his posts, too. In all likelihood I didn’t even think about the ambiguity of some of his statements, because I was interpreting everything in light of my pet theory that he subscribes to GRTt. I think he does subscribe to GRTt, but I may have missed some important positivistic views of his if I was only focusing on the project of his he likes. Some of the statements you cited where he discusses ‘meaning’ do create a tension with GRTt.
