Incompatibility between our big aspirations and the reality of life is bound to disappoint unless we learn to be a bit more gloomy, says Alain de Botton.
Today I want to advance the unusual idea that we'd be a great deal more cheerful if we learnt to be a little more pessimistic.And, from a completely secular point of view, I'd like to suggest that in the passages before they go on to promise us salvation, religions are rather good at being pessimistic. For example, Christianity has spent much of its history emphasising the darker side of earthly existence.
Yet even within this sombre tradition, the French philosopher Blaise Pascal stands out for the exceptionally merciless nature of his pessimism. In his book the Pensees, Pascal misses no opportunities to confront his readers with evidence of mankind's resolutely deviant, pitiful and unworthy nature.

A pessimistic world view does not have to entail a life stripped of joy. Pessimists can have a far greater capacity for appreciation than their opposite numbers, for they never expect things to turn out well and so may be amazed by the modest successes which occasionally break out across their darkened horizons.
