Talking over political problems and theories is useful for a variety of reasons. By having to frame your ideas and beliefs in words, you are forced to crystallize, to clarify them for yourself. Through discussion you can get fresh light on situations and fresh facts about conditions. Above all, you can get the stimulation and challenge of disagreement and learn to test your beliefs and opinions, to re-examine them from a fresh viewpoint. Of course, if you merely defend your opinion without re-examination, any discussion is quite pointless.
