The whole world is in some ways better than it's ever been in the past. And, indeed, I think for many people the meaning of their lives really depend… - John N. Gray

Hayek may still have lessons to teach us. The policies he recommended during the Great Depression may have been badly flawed but his insight that prosperity cannot be restored by unending expansion of debt may have some value at a time when the limits of “Keynesian” quantitative easing are becoming clear. It is in any case far from obvious that Keynes would have supported a continuation of QE once a disastrous collapse had been averted. “Keynesianism” is a confection of Keynes’s more mechanical disciples, not an indication of how this mercurially brilliant mind would have responded to our present dilemmas. Again, Hayek’s claim that nothing can be done to mitigate the impact of free markets on social cohesion was dangerously misguided. But he was right to point out that capitalism cannot be remodelled to fit some conception of an ideally fair distribution of resources. Whether any kind of social democracy can be reconciled with the anarchic energies of global markets is an open question.

The basis of the [scientific] method is a belief in natural uniformity – if two events are regularly connected in our observations we can conclude that they obey a universal law. But this is not a conclusion we reach by observation. No amount of evidence can demonstrate the existence of laws of nature, since new experience can always overturn them. Science rests on the belief that the future will be like the past; but that belief is rationally groundless. This is not a new line of thinking. David Hume argued that the expectation that the future will be like the past, which is the basis of induction, is a matter of habit. Hume wanted to show that since miracles transgress known laws of nature it was unreasonable to accept reports of them, in the Bible or anywhere else. But his arguments against induction showed that the laws of nature could not in fact be known, so events that seemed impossible could happen at any time. The upshot was that faith in miracles returned by the back door of sceptical doubt.

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.
