“A god abides with us still. And if we wish to see its face we need merely reach into our own pockets.”

Sequel to “Marx on Capital as a Real God” that expands on Marx’s comparison of money with Christ. I discuss Christ’s real presence, demon summoning, our collective dark enchantment, and how capitalism reproduces a great sacrificial exchange between a people and its god.

“The essence of money is … the mediating activity or movement, the human, social act by which man’s products mutually complement one another, is estranged from man and becomes the attribute of money, a material thing outside man. Since man alienates this mediating activity itself, he is active here only as a man who has lost himself and is dehumanized; the relation itself between things, man’s operation with them, becomes the operation of an entity outside man and above man. Owing to this alien mediator – instead of man himself being the mediator for man – man regards his will, his activity and his relation to other men as a power independent of him and them. His slavery, therefore, reaches its peak. It is clear that this mediator now becomes a real God, for the mediator is the real power over what it mediates to me. Its cult becomes an end in itself.”

K. Marx, Comments on James Mill, 1844.

The question I address is whether Marx’s “real God” is metaphor or science.

Talk presented at the Communist University 2020, organised by the CPGB (UK).

This talk examines the significance of the theory of computation for the perennial philosophical problem of the identity of thought and being. I give an accessible overview of the history and main results of computability theory, and then discuss the Church-Turing thesis and its generalizations. I then consider our epistemic states in possible worlds where we are, or are not, computationally equivalent to nature, and therefore under what circumstances we might break through the Turing barrier. The main argument is that deciding our computational equivalence to nature is transcendentally undecidable, and therefore will we never halt on this decision problem. In consequence, the identity of thought and being is a purely “scholastic matter” (Marx’s 2nd thesis on Feuerbach) and we have no rational reason to suppose that any persistent unintelligibility in nature cannot, one day, yield its secrets.

We cannot know we know; and we cannot know we cannot know.
