Instead of enabling humans to improve their lot, science degrades the natural environment in which humans must live. Instead of enabling death to be overcome, it produces ever more powerful technologies of mass destruction. None of this is the fault of science; what it shows is that science is not sorcery. The growth of knowledge enlarges what humans can do. It cannot reprieve them from being what they are.

Cheating ageing by a low-calorie diet, uploading one’s mind into a super-computer, migrating into outer space … Longing for everlasting life, humans show that they remain the death-defined animal.

Before Christianity suicide was not in any way troubling. Our lives were our own, and when we tired of them we were at liberty to end them. One might think that as Christianity has declined, this freedom would be reclaimed. Instead secular creeds have sprung up, in which each person’s life belongs to everyone else. To hand back the gift of life because it does not please is still condemned as a kind of blasphemy, though the offended deity is now humanity instead of God.

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.

Evangelical atheists preach the need for a scientific view of things, but a settled view does not go with scientific method. If we know anything it is that most of the theories that prevail at any one time are false. Scientific theories are not components of a world-view but tools we use to tinker with the world.

Though it is often assumed that naturalism must be hostile to religion, the opposite is true. Enemies of religion think of it as an intellectual error, which humanity will eventually grow out of. It is hard to square this view with Darwinian science – why should religion be practically universal, if it has no evolutionary value?

For a consistent naturalist science can only be a refinement of animal exploration, a practice humans have devised for finding their way in the bit of the universe in which they have so far survived. Instead of thinking of science as a law-seeking activity, we can think of it as a tool humans use to cope with a world they will never understand.

If our universe is one of many, unlike others in containing observers like ourselves, there is no need to posit a designer. Most universes will be too chaotic to allow the emergence of life or mind. In that case, the fact that humans exist in this universe needs no special explanation

The irony of scientific progress is that in solving human problems it creates problems that are not humanly soluble. Science has given humans a kind of power over the natural world achieved by no other animal. It has not given humans the ability to remodel the planet according to their wishes. The Earth is not a clock that can be wound up and stopped at will. A living system, the planet will surely rebalance itself. It will do so, however, without any regard for humans.

The basis of science is the empirical method, which uses the senses to build up a picture of the world; but science tells us that our senses have evolved to help us get by, not to show us the world as it is. Science is only a systematic examination of our impressions, and in the end all each of us has left are our own sensations ... The end-result of the empirical method, then, is that each individual is left alone with their own experiences. We can escape this solitude, Balfour suggested, only if we accept that there is a divine mind.
