You've amended your definition of "complete" to now include completability -- being subject to "definite completion", i.e. some process of accretion that has an end. So you're again begging the question by defining "actual" as "complete" and "complete" as finished/ finalized/finite. (Or, you've begged it by assuming that a completion process cannot be infinitely parallel, as Paul described.) > > all events are equally "existent", and that past/present/ > > future have meaning only with respect to particular events. > > When the event itself has ceased to exist, ie has > become past, what remains is a historic fact [..] > which has "shifted" from present to past tense "Becomes past" by what clock? Consider a (boring) movie of some clocks keeping time. What frame in the movie is "the present" in the movie? We can watch the movie, and use our own distinct time dimension (which has its own clocks independent of the movie's clocks) to say that the frame we're watching in our "now" is the distinguished "present frame" for the movie. But that requires two kinds of clocks -- the ones in the movie, and the ones on the wall of the people watching the movie. By contrast, the universe has only one kind of clock -- those in the universe's time dimension. There is no reason to speak of a clock outside the universe that tells which frame or instant or time-slice of the universe is a distinghished "now". Every instant is a "now" to the events that are temporally close enough to it. > > The notion of a "universal now" effectively (and unparsimoniously) > > assumes some second and separate dimension of time. > > You´re generally right.

Yes, "co-existing" avoids the mistake of assuming that there is a privileged point in spacetime. Note that neither criterion helps establish that an infinitude cannot co-exist (or be "here and now"). > > Since by "incompletable" you obviously mean "not having a last > > member", you are (once again) simply defining that you are > > right instead of demonstrating it. > > I mean that "being incompletable" is equivalent to "not being capable > of forming a definite whole". Right, and "definite" either includes "finite" in its definition, or doesn't. If it does then you've again begged the question, and if it doesn't then your argument hasn't made any progress. -- brian@holtz.org http://humanknowledge.net
