I don’t reject the intelligibility of reality. In fact, the intelligibility of reality is just as self-evident as I am.
By intelligibility I refer to our ability to discern truth and such, which is directly contradicted by solipsism.
Plus, the fact that I question the objectivity of reality doesn’t mean that I summarily reject any arguments that are based upon such an objective reality.
This is well, often I will start a debate by the outline “If you accept the PSR, and our ability to discern the external world, etc. then…”
Whether this leads inevitably to the existence of God and an objective morality is another matter however.
I’m sure based on your other claims, you’ve heard Aquinas’ ways. I would still like to give them a go with you though. I will quote Edward Feser’s first 14 points of Aristotle’s argument
- Change is a real feature of the world.
- But change is the actualization of a potential.
- So, the actualization of a potential is a real feature of the world.
- No potential can be actualized unless something already actual actualizes it (the principle of causality).
- So, any change is caused by something already actual.
- The occurrence of any change C presupposes some thing or substance S which changes.
- The existence of S at any given moment itself presupposes the concurrent actualization of S’s potential for existence.
- So, any substance S has at any moment some actualizer A of it’s existence.
- A’s own existence at the moment it actualizes S itself presupposes either (a) the concurrent actualization of its own potential for existence or (b) A’s being purely actual.
- If A’s existence at the moment it actualizes S presupposes the concurrent actualization of its own potential for existence, then either there exist a regress of concurrent actualizers that is either infinite or terminates in a purely actual actualizer.
- But such a regress of concurrent actualizers would constitute a hierarchical causal series, and such a series cannot regress infinitely.
- So, either A itself is a purely actual actualizer or there is a purely actual actualizer which terminates the regress that begins with the actualization of A.
- So, the occurrence of C and thus the existence of S at any given moment presupposes the existence of a purely actual actualizer.
- So, there is a purely actual actualizer.
If any of the terms are unfamiliar, or you disagree with a premise, just let me know.
