Excellent post on truth in writing, be it fiction or non:
A more useful criteria would begin with the understanding that all good writing seeks the truth, whether that’s a metaphorical or an objective truth, and it should be judged accordingly. Deciding if a book is “true” or not should never stop at the title page; a good reader should never suspend his or her critical faculties. This is precisely why reading is such a mentally interactive experience, why writing is — in my opinion — an essentially higher art than other, more passive media. While reading a book, one must constantly be engaged in trying to hear dialogue, visualize surroundings, judge character and background. A good book, in turn, challenges a reader; makes him or her rethink what they are sure they know and believe.
