If it is true that you need real numbers to simulate a brain then since real numbers are not computable the brain is not computable, and hence consciousness is not necessarily computable (although it may still be contingently computable). But what evidence is there that real numbers are needed to simulate the brain? -- Stathis Papaioannou -- You received this message because you are subscribed to the Google Groups "Everything List" group.
