“Darwin's theory of evolution by natural selection is the only workable explanation that has ever been proposed for the remarkable fact of our own existence, indeed the existence of all life wherever it may turn up in the universe.”

De Abaitua interview (1998)
Context: Mind has come up with this brilliant way of looking at the world — science — but it can’t look at itself. Science has no place for the mind. The whole of our science is based upon empirical, repeatable experiments. Whereas thought is not in that category, you can’t take thought into a laboratory. The essential fact of our existence, perhaps the only fact of our existence – our own thought and perception is ruled off-side by the science it has invented. Science looks at the universe, doesn’t see itself there, doesn’t see mind there, so you have a world in which mind has no place. We are still no nearer to coming to terms with the actual dynamics of what consciousness is.
