Well, OK, but that is completely at odds with everything the M&S says about reification. A reified statement is supposed to be a reification *of a statement*, ie of a triple, right? In your account here, the reification of the triple <mary> <hit> <ball> . has exactly the same content and meaning as the original triple. If this is the case, what is the point of using reification at all? All one has done is to provide another way to write the same thing. [Later. Oh, I see what the answer might be: same proposition, but not same assertion. Reification here isn't thought of as a metalevel assertion, but rather as a way of sidestepping assertion. The point being that the unreified triple is asserted in any graph in which it occurs, but the reification is not asserted. Is that the idea?] Tell you what, rather than get into an immediate debate about this, I will try to write a short summary of various views on what reification means, which that will give us something to refer to. (I now have four of them. ) I was planning to do this last week but got zapped.
