I was inspired by some discussion in other threads (about metaphysics and its first principles of existence/being, etc.), and have flushed a few insight's. And while this statement may also have some disparaging implications, there seems to be an aversion to metaphysical phenomena (physical and meta-physical things existing) particularly as it relates to the A-theist belief system (the 'concept' that there is no God).
Consider the question: what does it mean for something to exist (what is physical reality)? Whether its the laws of the universe or consciousness itself (subjective and objective phenomena/physical and non-physical) we know that there are both concrete objects and non-concrete 'things' that exist
( i.e., gravity/QFT, the Will, etc.). And if one were to consider that the former laws of nature themselves are pure objective truths (a priori), meaning truths that no matter what any one person thinks or feels about them are universally true (mathematics) and unchanging, what then would be an analogous proposition to the logical possibility of a God's existence? Does that somehow imply 'the concept' that God is a mathematician?
With that said, let's also assume that most Atheists consider all of life as 'logical' and that there is no paradox, contradiction, indeterminacy, logically impossible existing things, (no finitude) and so on that 'logically' or 'objectively' exist in the universe. Of course, that on its face would be false (and a self-refuting paradox), but for the sake of argument, let's assume it's objectively true. Let's further assume (lots of assumption's here) that every thing in life is unchanging and mathematically true (logical). And considering that mathematical truths (objective truths) which exist and are also metaphysical in nature, translates to a 'language' of analytical propositions, does the ontological or cosmological God exist as some kind of 'pure truth'? If God exists analytically, what would that mean?
Here's the classic Ontological argument that proves God's existence using 'pure reason' or purely analytical propositions:
1.By definition, God is a being than which none greater can be imagined.
2.A being that necessarily exists in reality is greater than a being that does not necessarily exist.
3.Thus, by definition, if God exists as an idea in the mind but does not necessarily exist in reality, then we can imagine something that is greater than God.
4.But we cannot imagine something that is greater than God.
5.Thus, if God exists in the mind as an idea, then God necessarily exists in reality.
6.God exists in the mind as an idea.
7.Therefore, God necessarily exists in reality.
And another (Cosmological):
1.Every contingent fact has an explanation.
2.There is a contingent fact that includes all other contingent facts.
3.Therefore, there is an explanation of this fact.
4.This explanation must involve a necessary being.
5.This necessary being is God.[19]
And finally:
1.Something can be produced.
2.It is produced by itself, something or another.
3.Not by nothing, because nothing causes nothing.
4.Not by itself, because an effect never causes itself.
5.Therefore, by another A.
6.If A is first then we have reached the conclusion.
7.If A is not first, then we return to 2).
8.From 3) and 4), we produce another- B. The ascending series is either infinite or finite.
9.An infinite series is not possible.
10.Therefore, God exists.
1.Whatever begins to exist has a cause of its existence.
2.The universe began to exist.
3.Therefore, the universe has a cause of its existence.
Philosophical Question: is the foregoing another example(s) of logical necessity? And if so, is the notion of a necessary Being absurd? And, if it's absurd, why?
