...what goes on inside believers is mysterious. So far as it can be guessed at - if for some reason you wanted to guess at it - it appears to be a kind of anxious pretending, a kind of continual, nervous resistance to reality. It looks as if, to a believer, things can never be allowed just to be what they are. They always have to be translated, moralised - given an unnecessary and rather sentimental extra meaning. A sunset can't just be part of the mixed magnificence and cruelty and indifference of the world; it has to be a blessing. A meal has to be a present you're grateful for, even if it came from Tesco and the ingredients cost you £7.38. Sex can't be the spectrum of experiences you get used to as an adult, from occasional earthquake through to mild companionable buzz; it has to be, oh dear oh dear, a special thing that happens when mummies and daddies love each other very much...

Our fingers must be in our ears all the time - lalala, I can't hear you - just to keep out the plain sound of the real world.

The funny thing is that to me it's exactly the other way around. In my experience, it's belief that involves the most uncompromising attention to the nature of things of which you are capable. It's belief which demands that you dispense with illusion after illusion, while contemporary common sense requires continual, fluffy pretending. Pretending that might as well be systematic, it's so thoroughly incentivised by our culture.
