Attaching epistemic significance to metaphysical intuitions is anti-naturalist for two reasons. First, it requires ignoring the fact that science, especially physics, has shown us that the universe is very strange to out inherited conception of what it is like. Second, it requires ignoring central implications of evolutionary theory, and of the cognitive and behavioural sciences, concerning the nature of our minds.

Of all the main historical positions in philosophy, the logical positivists and logical empiricists came closest to the insights we have urged. Over-reactions to their errors have led metaphysicians over the past few decades into widespread unscientific and even anti-scientific intellectual waters. We urge them to come back and rejoin the great epistemic enterprise of modern civilization.
