Conrad on The Writer's Approach to Art

"I would require from [the writer] many acts of faith of which the first would be the cherishing of an undying hope; and hope, it will not be contested, implies all the piety of effort and renunciation. It is the God-sent form of trust in the magic force and inspiration belonging to the life of this earth. We are inclined to forget that the way of excellence is in the intellectual, as distinguished from emotional, humility. What one feels so hopelessly barren in declared pessimism is just its arrogance. It seems as if the discovery made by many men at various times that there is much evil in the world were a source of proud and unholy joy unto some of the modern writers. That frame of mind is not the proper one in which to approach seriously the art of fiction. It gives an author—goodness only knows why—an elated sense of his own superiority. And there is nothing more dangerous than such an elation to that absolute loyalty towards his feelings and sensations an author should keep hold of in his most exalted moments of creation."

Perhaps as a cautionary note: despite the allusions to religiosity, Conrad's view need not necessarily have to be read in a non-secular way for it to be meaningful as a suggestion for a way of life.
