assistant: Hello Todd.
Please don't interpret the following criticism as a personal attack.
...
This statement seems vaguely worded.
I dispute this claim.
You seem to define a "moment" as an interval of time. Others may define a
"moment" as a single point on a continuous space such as the "real number
line". I have not yet seen any argument from you which shows that time is
not a continuum.  I'll keep reading.
I see no reason to conclude either of these:
(infinite time continuum) => (no "passage" of time)
(finite time continuum) => (some moments "have not happened")
I don't see how accusations of cowardice contribute to your argument.
If "we" means you and I, then no.  I do not agree with this implication.
I'm not sure how the intended recipient of your message thinks.
Disagreed.
You seem to be assuming that everything that exists has an external cause.
I dispute this assumption.
I regard this as still unestablished.
This reads like unsupported speculation.
Many do not regard the "progression" of time as a "sequence",
which is a discrete sort of thing, but as a linearly ordered
continuum with an uncountably infinite number of points.
Such a model renders all "chicken and egg" analogies faulty.
Again I dispute this implication.
This seems to hinge on the implication you have stated several times,
but which I dispute.  I have some other problems with this paragraph,
but until the discrete-vs-continuous issue is clarified, it is perhaps
best that I do not elaborate on them.
While I may not have seen this "everything I've told you so far",
it would appear that the contents of the message I am replying to
do not establish the finiteness of time, at least in many senses
of the word "finite".  I think what's needed most is a clarification
of terminology.
This conclusion seems to depend at least partly on an assumption that
everything that exists has an external cause, which I again dispute.
Mr. Rigor
