Kevin,
Your post was petty, manipulative and dishonest. Furthermore you failed to acknowledge a single point that I made and attempted to find fault with every small thing that I said ... perhaps you feel backed into a corner?
Laird: Until now you have tacitly accepted that you are modelling
Kevin: Definitely not. "Modeling" is something done by scientists, but since we are philosophers we don't do modeling.
You use language to describe reality; you have some unique things to say about reality: most certainly you are modelling and you don't fool me for a second when you deny it.
Laird: You model reality as a Totality
Kevin: Completely wrong. You are talking about "a Totality" as though there is more than one Totality, or as though there can be something other than the Totality, but you are wrong on both counts - of logical necessity.
So if you like, substitute the word "the" for "a". Got any disagreement other than the petty? And does this petty disagreement truly make me "completely" wrong?
Laird: that contains all causes but that is itself uncaused.
Kevin: That too is a logical necessity, and not a model. A model is only an approximation but these logical statements are absolutely and necessarily perfect.
No, Kevin, it's a model. As I've been repeating to David: logic cannot confirm for you that your model accurately reflects reality; it can only confirm that to date no inconsistencies have been found. And as I've explained, this model is not even consistent: it contains the paradox of uncausedness.
Laird: You model reality as a Totality that stretches infinitely in both temporal directions and in all spatial directions.
Kevin: You have a very short memory. The Totality necessarily includes time and space, by definition, and therefore it doesn't exist in time, and doesn't stretch in any directions.
I don't understand what you're disagreeing with. Where did I say that the Totality does
not include time and space? More pettiness I suspect, simply so that you can say "you don't understand and you're wrong".
Laird: You model reality as entirely deterministic.
Kevin: That things are caused is a logical and necessary truth, and not a model.
How patently ridiculous. Quantum mechanics puts up a very different model which is more supportable than determinism because it
actually has been observed through experiment to concur with reality. Really what your argument amounts to is this: I observe that causes exist, therefore all things are caused. A spectacular non sequiter if ever there was one.

No, it's like you drawing a picture of the moon and me saying, "Hang on, how do you know that there are dragons on the moon?" and you replying "Because it's logically necessary".
Laird: 1. The contradiction of an infinite past.
Kevin: The Totality doesn't exist in time, as explained above and many times previously, but you can try and refute something else if you like.
Phrase it however you like, Kev, but ultimately you believe that the past is infinite. That's all that I'm picking a problem with.
Kevin Solway wrote:Laird wrote:This contradiction can be demonstrated through a syllogism:
a. The universe extends infinitely back in time.
b. The past is characterised by the fact that the "marker of time" (present moment) has moved over it at some previous point in time.
c. It is impossible to reach an infinity, only to approach it.
d. From (c): the marker of time has never been at the most infinite early point.
e. (b) and (d) are in contradiction.
You say, "it is possible to approach infinity".
But this is obviously false, since no matter how far you go you can never be any closer to infinity. I don't think you've thought at all about what infinity is.
You've clearly forgotten your calculus. You don't remember "in the limit as x approaches infinity", do you?
Laird: the marker of time has never been at the most infinite early point.
Kevin: There can be no "most infinite early point". That's what "infinite" means. So you are talking about nonsensical, nonexistent things.
I didn't phrase that as well as I could have but it's testament to your petty need to find fault with absolutely everything that I wrote in that post that you quibble. Let me rephrase it as "the marker of time has never been at the earliest infinity" then.
Kevin Solway wrote:In addition, the present has indeed been all points in the past, by definition.
Indeed, that was (b) in the syllogism. Unfortunately for you it is contradicted by (d) in the syllogism, but you're on a mission to ignore every point that I make and find fault with everything that I say so of course you're not going to acknowledge that.
Kevin Solway wrote:Laird wrote: . . . uncaused Totality:
And yet we can put a name to it, so clearly it has boundaries of some sort
It has no boundaries to itself, but
its parts have boundaries (by definition). For that reason we can contrast it to its parts. Hence in-finite, or "not finite".
In fact it has boundaries in that it is limited to three spatial dimensions and one temporal dimension.
Laird: 3. The article of faith: that determinism trumps quantum mechanics:
Kevin: Logic trumps anything.
Uh, no. Reality trumps everything.
Laird: The best evidence and theories of quantum mechanics point to the fact that some events simply cannot be predicted whatsoever
Kevin: Whether things can be predicted or not has got nothing at all to do with determinism.
It has absolutely everything to do with it. And there's your problem. If you can't see that, then you have no hope of understanding what's wrong with your position. Determinism is based on the predicate that any particular event is completely predictable (fully "caused" in your terminology) given sufficient information.
Kevin Solway wrote:Many things are caused but unpredictable, like the throw of a dice, the weather, etc. There is absolutely no way I can predict what the weather will be tomorrow, or what the result of a dice throw will be, as single events, no matter what information I have access to.
Since you believe in determinism, then theoretically with all of the information in the universe (and probably with a lot less) the weather and the result of the dice throw could be predicted. This is in stark contrast to a quantum event, which - no matter how much information you have access to - simply
cannot be predicted. Hence quantum mechanics overrules determinism.
Laird: Some such explanation might turn up at some point in the future, but at the present it seems very unlikely
Kevin: People have arrogantly been saying exactly what you have just said for thousands of years. Some people believed the world was flat, or that the sun revolved around the earth, while others believed they were personally created by God. And they all believed they had reached the end point of knowledge, just as you do now (or at least, you think it is "very likely").
"And they all believed they had reached the end point of knowledge". Sounds like a pretty good description of yourself. The only difference is that you do it
in the face of compelling evidence to the contrary.
