I think metaphysics is the road to truth.
Truth is a very "final" assessment about a human inquiry.
Can you name an example of some final "truth" we now hold by virtue of a metaphysical process? I can't think of such a final truth at all (whether from metaphysics or not).
So is this truth at the end of your road something achievable, or is it an aspiration?
I think that the metaphysical process
is what matters to humanity, not the actual solution to any metaphysical problem.
There is no truth at the end of a metaphysical road -- none; but going down that road gives people hope
of truth. Why hope? Because using reason as our tool gives us ownership, i.e. it empowers. Using our senses gives the universe ownership.
And that's fine -- but we should remember that metaphysics is a human art and it lives and dies with the strengths, weaknesses, and expectations of the humans who engage in it. Whereas science may be bent and twisted, but in the end the raw data are still there whether a human mind is involved or not. There's more security in what we see and hear -- and thus a step closer to truth.
