Existence in itself may not have any "inherent value", Nor does it have any inherent purpose, but why does it matter? Is it really that horrible that existence within it's own percived value, is satisfactory enough, to continue it for it's own sake?
Why must there be some kind of outside variable (usally a deity of some kind), to justify life as significant. Further, wouldn't an unchangeable variable, actually limit purpose, as it will be affected consciously or not, by this outside variable?
Further, even for the sake of argument, that there is a deity, and it grants eternal life. How then nihilism invaildated? What is this deity accomplishing by it's own existence, and that of it's creations? If this deity is the inherent virtue of virtue, then wouldn't the existence of this deity be justified only by it's own virtue?
