Uniqueness is not the unique criterion! Other causes are not eternal or spiritual…
Do you believe spirituality and eternity are uncaused aspects of reality? If not what causes them?
I have pointed out that the First Cause is transcendent. Neither truth nor goodness nor justice nor freedom nor beauty nor love have a beginning or end. Unlike physical objects they are eternal, indestructible and they all converge in the First Cause.
This is just reification of adjectives. I do not accept such reification.
Are goodness, justice, freedom, beauty and love adjectives?
I would also like to see a proof that the First Cause is transcendent. It seems to me that its transcendancy is just assumed.
Do you believe anything is transcendent?
I say that the First Cause is dependent, therefore it cannot be transcendant.
Why is the First Cause dependent?
Persons have ontological priority over things because they are the causes of their actions whereas things are not.
You said “The time factor is irrelevant to ontological priority.” I do not see how the time factor is irrelevant to the priority of people over things. There was a time when there were no people, so in that time there was no ‘ontological priority’. You have not shown me that the time factor is irrelevant here.
How do you know there was a time when there were no persons?
You don’t believe persons are the causes of their actions?
Your question was about what is beyond space and time. I said there was much.
What evidence is there for your belief?
