And yet, for a writer of fiction, part of the heart remains that of a stranger, for what we are trying to do is to understand those others who are our fictional characters, somehow to gain entrance to their minds and feelings, to respect them for themselves as human individuals, and to portray them as truly as we can. The whole process of fiction is a mysterious one, and a writer, however experienced, remains in some ways a perpetual amateur, or perhaps a perpetual traveller, an explorer of those inner territories, those strange lands of the heart and spirit.
