The destiny of our age is rationalisation, intellectualisation and, above all, a disenchantment with the world. The success of science as a technique of forecasting has broken a spell; there is no longer a complete image of the world that can be revealed by rational knowledge. Scientific activity is no royal road to the gods, nor to the essence of the world, nor to the truth of nature lying hidden behind its outward appearances; the spell of mysterious powers to be discovered or invoked has died away with the multiplication and the success of objective, neutral, purely technical instruments for the mastery of natural phenomena. If science robs the world of enchantment, it is because it offers only instrumental answers to the questions we ask of it.
