If they are neutral, have I offered good reasons to persuade them? If they are sympathetic, have I done more than merely reaffirm their present beliefs? That is, have I perhaps enriched their views or encouraged them to act? If they are hostile, have I taken account of their positions, recognized their strengths but also called attention to their limitations, and offered a position that may persuade these hostile readers to modify their position?
