It’s not a matter of closing off inquiry. Rational argument (metaphysical analysis) is never certain. I wouldn’t say I’m more than 85% or 90% sure of the correctness of these conclusions. I don’t believe actual inifinities exist (sorry, you can’t do ontology if you taboo “exists”!)—but that doesn’t mean I would close off scientific inquiry into theories that assume they do exist. Deny that qualia exist doesn’t close off scientific inquiry, but what you’re suggesting is closing off rational thinking about what could be true.
