"The sort of learning which is not in the last resort edifying is precisely for that reason unchristian. Everything that is Christian must bear some resemblance to the address which a physician makes beside the sick-bed: although it can be fully understood only by one who is versed in medicine, yet it must never be forgotten that it is pronounced beside the sick-bed. This relation of the Christian teaching to life (in contrast with a scientific aloofness from life), or this ethical side of Christianity, is essentially the edifying, and the form in which it is presented, however strict it may be, is altogether different, qualitatively different, from that sort of learning which is 'indifferent,' the lofty heroism of which is from a Christian point of view so far from being heroism that from a Christian point of view it is an inhuman sort of curiosity."
