There is... in our day, a powerful antidote to nonsense, which hardly existed in earlier times - I mean science. Science cannot be ignored or rejected, because it is bound up with modern technique; it is essential alike to prosperity in peace and to victory in war. That is, perhaps from an intellectual point of view, the most hopeful feature of our age, and the one which makes it most likely that we shall escape complete submersion in some new or old superstition.
