“And I am infinitely saddened to find myself suddenly surrounded in the west by a sense of terrible loss of nerve, a retreat from knowledge into—into what?

“Science is not a special sense. It is as wide as the literal meaning of its name: knowledge. The notion of the specialized mind is... as modern as the specialized man, 'the scientist', a word which is only a hundred years old.”
