As the Genesis story teaches, knowledge cannot save us from ourselves. If we know more than before, it means only that we have greater scope to enact… - John N. Gray

Religion is not a primitive type of scientific theorizing, any more than science is a superior kind of belief-system. Just as rationalists have misunderstood myths as proto-versions of scientific theories, they have made the mistake of believing that scientific theories can be literally true. Both are systems of symbols, metaphors for a reality that cannot be rendered in literal terms. Every spiritual quest concludes in silence, and science also comes to a stop, if by another route. As George Santayana has written, ‘a really naked spirit cannot assume that the world is thoroughly intelligible. There may be surds, there may be hard facts, there may be dark abysses before which intelligence must be silent for fear of going mad.’ Science is like religion, an effort at transcendence that ends by accepting a world that is beyond understanding. All our inquiries come to rest in groundless facts. Just like faith, reason must at last submit; the final end of science is a revelation of the absurd.

The core of the belief in progress is that human values and goals converge in parallel with our increasing knowledge. The twentieth century shows the contrary. Human beings use the power of scientific knowledge to assert and defend the values and goals they already have. New technologies can be used to alleviate suffering and enhance freedom. They can, and will, also be used to wage war and strengthen tyranny. Science made possible the technologies that powered the industrial revolution. In the twentieth century, these technologies were used to implement state terror and genocide on an unprecedented scale. Ethics and politics do not advance in line with the growth of knowledge — not even in the long run.

Like other human freedoms, the freedoms embodied in market institutions are justified inasmuch as they meet human needs. Insofar as they fail to do this they can reasonably be altered. This is true not only of the rights that are involved in market institutions. It is true of all human rights.
