Perhaps the primary distinction of the artist is that he must actively cultivate that state which most men, necessarily, must avoid: the state of being alone.  That all men are, when the chips are down, alone, is a banality — a banality because it is very frequently stated, but very rarely, on the evidence, believed.  Most of us are not compelled to linger with the knowledge of our aloneness, for it is a knowledge that can paralyze all action in this world.  There are, forever, swamps to be drained, cities to be created, mines to be exploited, children to be fed.  None of these things can be done alone.  But the conquest of the physical world is not man’s only duty.  He is also enjoined to conquer the great wilderness of himself.  The precise role of the artist, then, is to illuminate that darkness, blaze roads through that vast forest, so that we will not, in all our doing, lose sight of its purpose, which is, after all, to make the world a more human dwelling place.

— James Baldwin, The Creative Process, 1962
