Nothing can take the place of the individual, especially if the individual embodies in himself not the mechanical element but the element of cultural creativeness. No pupil can take the place of the master in completing a great picture which he has left unfinished; and just in the same way no substitute can take the place of the great poet or thinker, or the great statesman or military general. For the source of their power is in the realm of artistic creativeness. It can never be mechanically acquired, because it is an innate product of divine grace.
