I was commenting on your claim that science and philosophy look at reality at different levels. Methinks not really. Science was once called natural philosophy, it’s just reasoning based on evidenced inquiry. Although I guess some philosophers go further than the evidence permits by interpreting the science, for instance a lot of them interpreted Newton’s laws of motion to mean we’re in a clockwork, fatalistic universe until Einstein and others used further evidence to prove them wrong.
The First Way is basically a scientific argument in that it appeals to evidence, Thomas says things like “It is certain, and evident to our senses”. He follows that with a prediction of sorts: “that in the world some things are in motion”. But of course that’s wrong, he didn’t realize that
everything is in motion, that had to wait for Teresa de Ávila.
He makes another prediction, that “what is actually hot cannot simultaneously be potentially hot”, and uses that to support the assertion that there is “potentiality” and “actuality”. But that also turns out to be wrong from what we now know.
His piece of wood contains trillions of molecules, each “jiggling” with kinetic energy. The average rate of jiggling is called the temperature. End of story. No potentia required. Indeed within his piece of wood, whatever its temperature, some molecules jiggle a lot faster than others, so his assertion is incorrect as the wood simultaneously contains “hot” and “potentially hot” molecules.
You could try to avoid this problem by doing some violence to his argument, and saying it only applies to one molecule rather than trillions - one molecule can’t jiggle at two speeds simultaneously, right? But curtains, that runs you into the troublesome beast known as Schrödinger’s cat.
I’ll stop enumerating the problems with the First Way now until someone has a go at those already raised.
