"You keep using that word. I do not think it means what you think it means."
Seriously, I don't get your objection. For one thing, it's a statement of fact contingent on absolutely nothing but the world we know.
2) It is not logically impossible to create understanding without context. Not only this, it has never been seen as such. The christian God, for example, has always been omniscient. It didn't live through every possible situation to acquire it.
I disagree completely. Data may be possible, but with no context, understanding is not.
As to your example of God, the Christian God (Abrahamic, for that matter) is understood to be utterly unique and without peer, much less rival. Humans, not so much.
What is the relevance of moral awareness when there is nothing immoral to be seen/done?
There is none, of course. The question is whether such a state is preferable when human desires are set aside. I don't believe it is.
To cite an example: we could still have justice without injustice.
The exception that proves the rule. Even then, we would have no understanding of justice or its worth.
1) Unwanted pain stands in opposition to happiness. Unwanted pain decreases your well-being.
Is happiness the ultimate benefit? I think not.
Well being is increased by wisdom, which is often born in unwanted pain.
2) It is pure conjecture what you would want in a world like that.
Sauce for the goose is sauce for the gander - it's pure conjecture to say you wouldn't want to die.
But you mistook my phrasing. I DON'T want to be immortal. Not in this body, not in heaven.
3) You wouldn't need pain to learn anything ( useful ).
Contingent conjecture.
If you'll indulge me, my thoughts on sin and evil were beautifully articulated in an article elsewhere. Do you have the time and patience to read for a bit?
