Regarding his take on the hard scientists being positivist, I think that's more him trolling fuckwit theorists and philosophers whose heads went up their own socially constructive strong textualist arses.*
*that is if we accept the commonly used and socially contingent notion of head within a given symbolic matrix including the correct co-ordinates for the anatomy of an imagined singular body and it's rear and which is laden with a deep rooted contempt for bodily functions and organs that stand in opposition to those privileged with being the seats of cognition and the self.
Why does he talk about quantum mechanics? He does it an awful lot. I keep stumbling across it. I think there is a clear acosmic agenda going on.
Here look:
http://www.lacan.com/zizisolation.htmlOne should thus get rid of the fear that, once we ascertain that reality is the infinitely divisible, substanceless void within a void, "matter will disappear." What the digital informational revolution, the biogenetic revolution, and the quantum revolution in physics all share is that they mark the reemergence of what, for want of a better term, one is tempted to call a post-metaphysical idealism. It is as if Chesterton's insight into how the materialist struggle for the full assertion of reality, against its subordination to any "higher" metaphysical order, culminates in the loss of reality itself: what began as the assertion of material reality ended up as the realm of pure formulas of quantum physics. Is, however, this really a form of idealism? Since the radical materialist stance asserts that there is no World, that the World in its Whole is Nothing, materialism has nothing to do with the presence of damp, dense matter - its proper figures are, rather, constellations in which matter seems to "disappear," like the pure oscillations of the superstrings or quantum- vibrations. On the contrary, if we see in raw, inert matter more than an imaginary screen, we always secretly endorse some kind of spiritualism, as in Tarkovsky's Solaris, in which the dense plastic matter of the planet directly embodies Mind. This "spectral materialism" has three different forms: in the informational revolution, matter is reduced to the medium of purely digitalized information; in biogenetics, the biological body is reduced to the medium of the reproduction of the genetic code; in quantum physics, reality itself, the density of matter, is reduced to the collapse of the virtuality of wave oscillations (or, in the general theory of relativity, matter is reduced to an effect of space's curvature). Here we encounter ANOTHER crucial aspect of the opposition idealism/materialism: materialism is not the assertion of inert material density in its humid heaviness - SUCH a "materialism" can always serve as a support for gnostic spiritualist obscurantism. In contrast to it, a true materialism joyously assummes the "disappearance of matter," the fact that there is only void.
Is that just trolling? Or has he lost the plot? It's hard to tell. This is perhaps why I prefer watching him to reading him, the non-verbal communication adds something.
