So why is it non-fiction rather than fact? I wouldn’t call myself a non-man?
I suppose calling your book a fact book might not be accurate. Your view on the healing power of apple peal and comfrey in an alternative health book, might not be viewed by everybody as fact.
Or a GCSC science book discussing evolution, may not be considered fact by the folk that believe our planet was creatively designed.
I wonder what might be a better word?
