A bold philosophical defense of existential nihilism based on modern science. * * * When we imagine a machine, the result is always something close to a mechanical system that works by itself. It doesn’t bother us to think that it’s nothing beyond that. But how do we feel when we imagine ourselves as a machine? Empty. We have the feeling that something is missing. And what is missing? What’s there in a human that is missing in a machine? Illusion. The emptiness of the machine is the consciousness that our subjective world is a fiction; the consciousness that our humanity is a delirium, and that there’s nothing behind what we are living. We are machines, and our consciousness is a dream of this machine. Nothing else. Absolutely nothing.
