All I mean by that is the I think unreachable aspiration of some fully "correct" and consistent description of reality that is external to it. So say you had a theory of physics with internally consistent logic that was capable of providing a priori an empirically accurate model of our reality at every measurable scale, and could explain perhaps some of the odd details of the standard model of particle physics. That would represent some sort fully complete knowledge of all that could be, and the nature of chemistry, biology, human psychology, and all of reality could in theory if not in practice be calculated out mathematically, given a theory that describes a complete set of laws that do not need to be extended. The question of what is True and if it is reachable is whether such a theory actually exists, or if our reality is something that we in fact can be certain of little because of the necessary limitations of only knowing to ask questions that can be, these days entirely via technological perceptual extensions, which is what a telescope or a particle accelerator really are as far as human society is concerned, be inferred by our bodies of flesh and juices.

I would argue that this kind of approach to science philosophy is very common, usually unexamined and implicit, and a sort of identification of the ultimate goal of science as a whole to be the project of carving out Hegel's Absolute Idea from the bedrock of human sense experience. I think such a theory is impossible, and much of our rumblings about what we might be able to do with the majority of scientific research, particularly in physics, to find new contradictions to explore is guided by the same sort of impotent death drive as Silicon Valley startup cults or any other late capitalist social enclave. And I would argue this chiefly because we are not particularly rational about pointing science at the alleviation of human labor and suffering because unprofitable scientists are only good for being pointed at exciting and flashy PR and news to get people to focus on something else than the crushing weight of capitalist society even here in the imperial core. That isn't to say that the science these people do is wrong, it's that they could be helping people, and instead they're running exploitative little startups in the pursuit of knowledge that is not useful for people's lives. We don't even get to see how much human labor and suffering could be alleviated by increased development and production if we had a system of globalized central planning and an intensive project of feeding and housing people to build efficient and automated production pipelines for the majority of necessary commodities. We're basically there, technologically speaking, to completely revolutionize human society into communism. We have the brainpower. But right now, the brainpower available is doing the atheist scientist equivalent of seeking to meet God in person in this life.
