If God is pure consciousness, it appears we cannot "know" whether higher consciousness may be superior to matter. The "evidence" squints ambiguously between the quantitative and the qualitative. We can believe or not believe, on evidence, that some aspect of consciousness that connects us persists through countless metamorphoses of beliefs that are signified in forms. For all we know, even God may reason likewise: "I may have only this one unfolding of universal consciousness. After that, nothing. I may as well make the best of it while I can."
If one assumes materialism proves only materialism, one will be biased against all evidence that is not quantifiable in materialism. If one assumes immeasurable aspects of consciousness abide, on par with, or possibly superior to, materialism, then one finds "evidence" in qualities of inner experience. However, these are not facts; they are only truisms. They are given their force of "truth" by assumptions, based on first assumptions ... by consciousness. The lights for "convincing" will not come from exterior facts, but from interior intuitions.
To my lights, it would be hard to believe in higher values without believing in a reconciling, higher purpose. Even were civilizaton to acquire capacity to nurture artificial intelligence for being expressed through machines, such expressions of self awareness may well intuit their own connections with higher values and purposefulness. Regardless, as to persons such as Horowitz and others, I am more concerned with how their beliefs may be consistently illustrated in their actions than I am with whether their attempts to achieve philosophical consistency may encounter glitches.
The only reconciling value or higher purpose I have intuited is this: Consciousness, having no choice but to abide, seeks to comfort and entertain itself by availing communications of understandings and empathetic appreciations of sacrifice. In that respect, there abides continuous striving towards decent civilization, i.e., a City of God. As that vision becomes imprinted and associated with genes, genomes thus expressed may become children of a City of God, such that no power on earth will subjugate the essential quality of that genotype.
If the whole of our universe were nothing more than a flux of mathematics and equations, predestined and predefined from its origination, then, limited to that relation, our unfolding would be of little more meaning or import than a mindless Truism (like Rand’s “1 is 1"). We would not experience “Facts” made separate in any quality for themselves, but only truisms, all derivative of, and merely variations of, one original, encompassing, unifying, synchronizing, limiting fact. However, each of us has inside information to the contrary. That is, we "know" we are not mindless, nor without capacity for guiding and attaching meaning to our several experiences of unfolding facts. We know we have Will to apprehend, summon, define, and commission such facts as suit the unfolding parameters that are availed us for expressing our freedom. Thus, there are substantive and Quantitative “facts,” but they are of a Quality that is not independent of a Field of consciousness, which Field makes potent enough Perspectives of consciousness to accompany and attach to every expression of substance. There are no substantive facts that are more than truisms, unless they are tied to facts inter-functioning with consciousness at some level.
