Hello, this is my first post on this site, so I apologize if I make any mistakes.
Anyway, here's the main point of my post: should we accept Thomas Aquinas's Cosmological Argument as truth? For those unfamiliar, this is the argument in full form.
1) All beings (including the universe) are either contingent or necessary.
2) Not all beings can be contingent (because of cause and effect, a physical law found in the physical universe).
3) Thus, there must be some necessary being or thing that all of its contingencies depend upon.
4) This necessary being or thing is what is known as God.
So, what do you guys think? Does the law of cause and effect in the physical universe necessitate a root cause (God) that is free of the physical universe? Or could something exist as a necessary being without it existing a contingency in the physical universe as well?
Is he right?
