What observations undermine any of his premises? Even on the quantum level, being does not arise from non-being.
Sure that is what the quantum fluctuation is, a process of pair production and annihilation, where particles arise out of the zero point energy and then disappear back into it.
punkforchrist:
You are making two points, then. 1) Aquinas’ proofs rely on empirical observation, but observation may be doubted.
Yes, to the first part, because Aquinas’ five points are based on the similarity between characteristics of nature (the need for a mover or a generator) and these can only be recognized or determined based on observation of creation. But the second issue is unimportant and not needed to show Aquinas’ observations in error.
punkforchrist:
Therefore, 2) the observations that Aquinas makes may be mistaken.
And indeed we know that they are as the events surrounding quantum mechanical and other high energy physics events do not behave in the same way as the macroscopic Newtonian events Aquinas was familiar with.

I agree with this in the sense that we cannot have absolute certainty of observation. However, if we are willing to doubt even the most indubitable conclusions of our senses, then anything goes. It is true that I do not have absolute certainty that I am typing this post on my computer, but to be honest I do not see the significance of admitting that I do not have absolute certainty. Even those who try to reject their observations cannot live without them.
I am not trying to doubt all observation, only the extension of a set of observations to a general principle as Aquinas does. The error comes in that a general principle can be dis-proven by the introduction of another observation, unknown to the first observer, that does not fit the extension.
Aquinas observed the world, or more likely he relied on others to do so and thus create a language to describe it. He then used several key characteristic all of creation seemed to exhibit as an axiom and used that axiom as his premise. Those premises were :
1 Anything moved is moved by another
2 Anything caused is caused by another
3 If everything were contingent, then at some time there would have been nothing – and so there would be nothing now – which is clearly false. So not everything is contingent. So there is a necessary being. This is God.
4 Whatever is great to any degree gets its greatness from that which is the greatest.
5 Whatever acts for an end must be directed by an intelligent being.
But we see in science things that:
1 Move without the effect of others by coming out of the zero point energy - as in the motion of the particles during pair production and annihilation.
2 Come into existence without being caused by another - as in the generation of entire universes in the big bang from deSitter space.
3 Are not contingent on other things (like both quantum fluctuation and deSitter space itself) and we also see the second aspect of his point regard the need to nothing to lead to only nothing has already been refuted in the rebuttals to both points 1 and 2.
4 Show greatness is not a concrete quality but an abstract, arbitrary and relative one which is not transfered from one that is greater to one that is lesser.
5 Appear to act intelligently that have other mechanisms than an intelligent being behind them. This is once again because intelligence is an abstract, arbitrary and relative term which can be applied to any number of things by one individual and not applied to those same events by another.

In what sense do we know that nature is not as we observe it?
We don’t, but we can say it is not as Aquinas observed it, because the predictions of the science of that world view are less successful than the predictive power of the science behind the modern view which includes these new observations, one Aquinas was never even aware could occur.
punkforchrist:
As stated above, quantum theory does not negate the law of causation, so I do not see any evidence that falsifies Aquinas’ argument.
Where above did anyone prove that quantum theory does not negate the law of causation? I think you are assuming something that has not been shown.
