Arguments Against Thomistic philosophy

[vulcanlogician]

I don't think it can specifically establish Christianity over any of the other monotheistic religions. Just that it can establish theism and thus refute atheism.

For the actual argument, it is basically:

1. Change involves a potential being actualized
2. A potential must be actualized by something already actual
3. Some things do not exist necessarily and require their potential for existence to be actualized
4. If the thing doing this actualizing has potentials, it would also require another actual thing to actualize it
5. Therefore the chain of actualization must conclude in some purely actual thing
6. Since this thing would be  purely actual it would be unchanging and eternal
7. There could only be one such being as there would be no unactualized potentials to differentiate one such being from another
8. Since it caused all non purely actual things it would be omnipotent
9. (EDIT Forgot to include.) Since all non purely actual things, including intelligent beings, came from this Pure Actuality, it would neccessarily be both intelligent, since a cause cannot give something it does not at least possess virtually, and all knowing since the attributes of all things flow from it
10. And that is basically the monotheistic God

This is very bare bones. The article I linked presents an alternative argument that gets to the same conclusion. If you are worried about bugs just Google "Edward Feser Avicenna" and it should be the first to come up.

I'd also like to note that I would prefer direction to good atheist books, articles, or arguments. Debating this in a forum is not ideal but I am open to it if no one has read anything that would work.

I know little about Aquinas, but I'm not very impressed by the argument you've presented here. Polymath did a pretty good job of tearing it up.

It might benefit us for someone to come in and argue on Aquinas's behalf. Neo-Scholastic (as his username suggests) really gets off on Aquinas; he might be able to present the argument more charitably. Perhaps he'll drop into the thread and give his two cents.
