Throughout the 20th century, quantum mechanics was celebrated as the ultimate proof that modern science is leaving behind deterministic mechanical materialism and admitted that it is dealing with non-material entities; moreover, the notion that our reality takes place through being observed opens up to a subjectivist denial of objective reality. Some quantum scientists themselves claimed that the only way to account for our entire universe is to presuppose a global external observer (i.e., God).
The text rejects not only this direct theological solution but also the traditional “realist” stance which secretly relies on a divine dimension (the divine status of natural laws). It proposes a reading of the ontological implications of quantum physics which opens up the way for a consequent materialism, even if, from a traditional reading, this may appear to be an odd materialism without matter.
Extract: "The passage from universal doubt through certitude to cogito ergo sum (as a res cogitans) is not as smooth as Descartes’ deduction implies. Anxiety arises when my trust in everyday reality breaks down, when I see that I cannot rely on any figure of the big Other, that the big Other is not just deceiving but deceived itself, inconsistent.
The paranoiac vision of a genie malin, a deceiving god which is a fantasy reaction to the true anxiety: it reestablishes the big Other who controls things, although in the evil form – the big shift happens here, my belief in a big Other who controls things is restored. Then comes the third moment, the proof that god cannot be a cheating deceiver but must be truthful. So the first form of certitude is not simply the certitude that I exist even if all objects of my thoughts are hallucinations; it is the negative certitude that I cannot rely on anything or anybody. This certitude “is the opposite of the certitude of being, it could rather be formulated in this way: I know (that the Other is inconsistent, that it can cheat me, and that, for this reason, my knowledge provides no solid ground), therefore I am not. We are dealing with the certitude of non-being.
Even before God enters, there is a subtle shift from “I doubt about everything” to “when I doubt, I think, know this, so I am”: at the high point of anxiety, when I am certain of my non-being, I am a pure void of a subject, because I am (as a subject) only insofar as the Other is inconsistent. “I am not” means that I am barred from being a subject – the moment I say “(I know that) I am,” I am no longer a subject, I transpose myself into the domain of objective reality where I am one among the existing things which are the object of science."
