Fine tuning claims the universe is amazingly finely tuned to be hospitable for life. “The improbability of the fortuitous origin of life” claims that the universe is very inhospitable for life.
Exactly!
Sorry, but “Exactly!” …what?
“Exactly!” you accept that the two are diametrically opposed, and you withdraw your claim that the one proves the other? Or “Exactly!” you have completely missed or ignored my point? The two are not quite irreconcilable, but to make both claims you have to meet not only the incredibly high burden of proof for each claim, but also show that the ‘inhospitable’ universe of the “improbability of the fortuitous origin of life” argument is as hospitable as any possible universe could be. Otherwise the universe is not finely tuned.
- This universe is extremely inhospitable - as we have seem from the virtual extinction of life on this planet on several occasions.
- Yet life has emerged because the physical constants of this universe correspond exactly to the requirements for life.
- So many other conditions have to be fulfilled that life is extremely rare even in this universe - let alone all possible universes.
- Yet against overwhelming odds life has survived and is flourishing on this planet .
The best available explanation is superior to no explanation whatsoever…
.
Code:
a) That is the fallacy of the argument from ignorance
b) I would of course argue that the best available explanation(s) is(/are) the scientific one(s) with (famously) no need for the God hypothesis.
a) and b) are contradictory unless you explain why the best available explanation(s) is(/are) the scientific one.
Code:
c) that is in any case a non sequitur. You have not met the burden of proof necessary to claim that
Code:
(1) life is too improbable to occur naturally in this universe
(2) this universe is 'finely tuned' to make life as probable as possible
or
(3) (in order to reconcile 1 and 2) that "too improbable to occur naturally" is as probable as life can be in any possible universe.
You have not even given a scientific explanation, let alone met the burden of proof!
How can one possibly discuss the three topics without reference to one another? They are inseparable in a discussion of biological Design.
You can reference them (although I don’t see that you cannot discuss one without needing to discuss another) but you don’t need to confuse them. e.g. by replying to a response about fine tuning as though it were a response about abiogenesis.
Fine tuning is directly based on the inadequacy of the abiogenesis hypothesis.
It isn’t a problem for me because the point of a philosophical discussion is not to pick a fight or convert anyone but to clarify each person’s views. It is certainly not a one-sided affair where one person has nothing to offer. As Lear said, nothing shall come of nothing…
So why demand (apparently) that I make a bold assertion for you to attack? I have made assertions, in this thread and others, but where they appear (to me) to require supporting evidence I have tried to provide it. e.g. giving a link to John Webb’s evidence that physical ‘constants’ may in fact vary over space in this universe.
Please produce the verifiable evidence that physical constants vary - and vary sufficiently - to refute the improbability of life in this universe.
Otherwise, it is true that where you are the only one making bold assertions, you are the only one who needs to provide evidence to support those assertions. If that seems unfair to you, the only thing I can suggest is limiting yourself to assertions you can support with evidence.
You seem to be unaware that “I would of course argue that the best available explanation(s) is(/are) the scientific one” is a very bold assertion - for which you certainly need to provide evidence…
If that seems unfair to you, the only thing I can suggest is limiting yourself to assertions you can support with evidence!
