And yet the that part of the text remains inspired. It is his inspired opinion, unbeknownst to the hagiographer himself. Prophecy does not require that the prophet knows he is prophesying. See Caiaphas, for instance, saying Jesus would die for the people…
Except that the words of the Preacher are actually self-refuting.
If taken literally, and “all is vanity” that would mean his claim that all is vanity is also a vain claim. Ergo even his claim is devoid of meaning and significance and cannot be a substantive one.
The words of the Preacher, the son of David, king in Jerusalem.
Vanity of vanities, says the Preacher,
vanity of vanities! All is vanity.
So if his claim is an inspired one, then precisely what does it mean?
It must mean that his capacity to judge all (qualified as all merely human attempts to impose meaning upon reality) to be vanity, must itself have come from a non-vain and not merely human source.
In other words, he can only claim that all is vanity if he is coming from a perspective that can properly judge what is and what is not vanity. Otherwise, his claim is also merely a vain one.
Ergo, the “all” that he refers to is not all in an unqualified sense, but all in the sense of all merely human attempts to impose meaning and value upon reality.
The Preacher, then, is implicitly claiming to be seeing things from a non-vain (divine or inspired) perspective which can property judge the human perspective to be vain.
It is similar, I think, to Socrates’ claim to know nothing. How could he possibly know THAT without having a direct intuition of what it means to know anything (or everything) at all and seeing directly as a result that what he does know is nothing in comparison to what it means to actually know.
Paradoxically, I think this is something like the argument that Qoeleth proposed in the opening post. We can’t know things are meaningless without having some direct insight into what is truly meaningful.
As CS Lewis pointed out, fish don’t know they are swimming in water precisely because they are so totally immersed in it. They have no perspective from which to see themselves swimming in water. Unless we have a perspective that transcends the merely human we cannot know that the merely human that we are immersed in is pure vanity.
If that insight into the human condition is significantly true, then it cannot be merely a human derived insight, it would have to come from a transcendent source. Otherwise, we could not know for certain that it is true, just as fish could not know for certain that they are swimming in water without getting out of the water, transcending it, and looking at themselves swimming in it from an outside perspective.
