A strict “it's all just matter and energy arranged in various ways” kind of materialist, not the vulgar reductionist kind that skips the “various ways” part of the equation, but completely unwilling to countenance the existence of a separate transcendent plane of being that influences, interacts with, directs, or gives meaning to our being on the plane of immanence of our very material reality. A kind of Spinozistic monism shot through with modern physics, Nietzschean will to power, and Heidggerian “being-there.”
Yes, demons, gods, fates, furies, muses, Bodhisattvas, and chimeras do exist, but their existences are determined by the flows of matter and energy between already constituted individuals, which despite being “things” are nevertheless ephemeral, temporary, and always in flux. You can never step in the same river twice; that's true, but you can also only fuck the same lover once, embrace the same mother once, give alms to the same beggar once, and write a single word only once. All of these prosaic things and their seemingly mystical, mythical counterparts like Dionysus, the Great Pan, Yahweh, Ba'al, Kali, Quetzalcoatl, Minerva, and Loki are just ever-changing material flows that have a capacity to affect other flows and be affected by still other flows in turn. Flows of shit, flows of oil, flows of wine, sperm, sea water, menstrual blood and the blood from wounds, flows of mud, quicksand, chicken stock, fish guts, and clear plum brandy. Flows of gravity, flows of dark matter, flows of ionizing particles released by the sun, their speeds exceeding the solar escape velocity. Flows of language, pheromones, hormones, stomach acid, bile, intestinal bacteria, and neurotransmitters. Flows even of photons reflected off the surface of bodies and emanating from the destruction of matter rejecting the dualism of particle and wave.
