Vlad,
The evidence is observed contingency.
First, you’re still stuck in the unqualified assumption that that which operates
within “the universe” must also apply
to the universe itself. You keep ignoring this, but that doesn't make it go away.
Second, it’s by no means certain that the universe functions entirely on a “contingent” (ie deterministic) basis in any case – “true” randomness for example is a real possibility at the quantum field level.
Third, your argument is structured the same way that black swans were said not to exist because none had been observed…until some were. You cannot just jump from the current state of knowledge (even leaving aside the quantum field evidence) to a categoric statement of the non-existence of something. An orbiting teapot hasn't been observed either - does that fact justify the claim that there categorically isn't one?
As so often before, you're all over the place here.
You make evidence the most important demand of your credo and then just flippantly own up to not having any?
Yet again: if you don’t like evidence as the means to justify beliefs, what method would you propose instead?
Do you intend to run away from this problem forever too, or what?
My evidence is observed contingency…
Which fails as “evidence” – se above…
…and following that through logically.
Which fails as “logic” – see above.
I have told you I don't propose that God just is.
Yes you do. Why god rather than not god is your problem here.
I propose he has sufficient reason within himself…
Sorry, if you want to deny that the universe could be “sufficient reason within itself” for its existence then you can’t just special plead the identical argument to be legitimate for the “explanation” you want to fill the gap.
…and that a just is statement i.e. Russell, Is just an attempt to stifle the very notion of sufficient reason.
Still you don’t understand the difference between necessary and sufficient. Not sure why given how often it’s been explained to you, but you can’t move forward on this until it finally sinks in.
And here's the thing. Russells action in that respect was deliberate to prevent everyone seeing that his wagon had no wheels, that the emperor had now clothes and that the type of atheism that descends from him looks like just one massive courtiers reply.
If by “Russell’s action” you actually meant his comment that the universe is a “brute fact” then it’s none of these things. Rather it’s the statement that we have no choice but to accept the universe as a fact even if we cannot (yet at least) answer the deepest questions about it. By contrast, there’s no such basis to accept the various claims and assertions of supernatural answers some would attempt to answer those questions that actually have no explanatory value at all.
Apart from all that though…
