i think that the relation goes “if x has an earliest moment in time then x began to exist”.
I understand; you’re establishing an analytical synonym. We must be cautious, however. We’re conducting philosophy in natural language. Words in natural language have not only denotations (their explicit meanings) but also
connotations; their implicit meanings. As long as we’re careful not to import the connotations of any terms into the argument without explicit justification, we’re all right. But even professional philosophers import connotations (it’s hard to tell whether by accident or design) so we must always remain vigilant.
A) why should we believe that the universe is a “composite entity”?
Because it is defined to be a composite of all simple material things.
B) acceptance of the principle of causality is no more an example of hasty generalization than is acceptance of principles like non-contradiction, identity, or excluded middle; it is a principle, and is not accepted based (solely) on sample sets.
Quite the contrary. “Causality” is not analytically or logically justified. It’s certainly
empirically justified, but only with regard to individual, simple entitites.
Non-contradiction asserts the
meaning of logic. The excluded middle asserts the completeness of (at least first-order) logic. Identity is (at best) just a restatement of noncontradiction. Causality, OTOH, can be affirmed or denied without violating either non-contradiction or the excluded middle. It is not a logical necessity.
C) it (the KCA) is not subject to the fallacy of composition for the reasons i have already noted.
I don’t think you’ve established that.
D) of course it can simply be denied - anything can simply be denied.
Indeed. And thus we require
arguments for the acceptance or rejection of a premise. Does the assertion or denial entail a contradiction with other premises? If so, we have to reconcile them (if we are to remain rational). Does the assertion or denial entail a contradiction to observed fact? If so, we are rationally compelled to go one way or another to preserve observed fact.
But if neither of these cases obtain, then the fact that we can deny a premise without irrationality means that the argument fails to rationally compel acceptance of the premise and the conclusions which entail from it. Which is the point of this thread: Because the First Cause arguments attribute a property to the Material Universe without sound justification (their “justification” rests on the unsound premise of Composition), the premise and the conclusion can be rejected without loss of rationality.
Of course, the premise and conclusion can be
accepted without loss of rationality; it is certainly not irrational to believe the Material Universe was, in fact, created. But the
argument does not compel
acceptance of the conclusion, and does not establish a reason to doubt Scientific Materialism.
look, there are just no knock-down, drag-out arguments to be had about the (non-)existence of god; it comes down to plausibility and one’s ability to be compelling. i can assure you that after about 20 years of my having learned, written about, and rehearsed these and numerous other philosophical issues, you will not be able to convince me of your reasoning, even if it was immune to any obvious problems…
Well, rebutting the First Cause argument should not compel belief that the Material Universe is uncaused; the rebuttal doesn’t argue that. The rebuttal should, however, convince you that First Cause arguments are
not successful rational arguments.
and i’m almost positive that i am not going to be able to say anything to you to be able to make you change your mind.
Empirically, you’re probably correct. In principle, though, I could change my mind.
so. in my experience, when it gets to the point of “well, i just don’t believe in (universality of) the principle of causality”, the discussion has run its course; at that point, there is simply nowhere left to go, since i can’t provide a demonstration of the principle by recourse to other prior and more obvious truths, and any attempt at dialectical proof runs into the same “i just don’t think that’s necessarily true” rejection.
Hence acceptance of universal causality is, at best, optional; it cannot be the foundation of a rational
argument. It is, I suppose, a matter of unprovable faith.
thanks, though. it’s fun occasionally to engage in discussions like this.
It is indeed!
