    Logical fallacies and online mediation/conflict resolution don't really seem to go hand in hand. In order to find out the truth, behind something, one must present all variables. How can this be done when online? I think it's to complex to do so. Is this your point? If it is then I get that.

      Take for instance the post made at 8:19am. brainstorm.tribe.net/thread/...93d2fdc8 - This person is very sure of him/herself and his/her world view on the behaviour of others. How is that someone can assert such knowledge when in reality them asserting such is, in theory, trollish behaviour. Take for instance bravity. Is one not brave if they do not stand up to their abusers (percieved or otherwise) or are they infact brave because they don't succumb to their weaknesses that being retaliation through upset and anger. What if retaliating is the easiest way to deal with issues of abuse but the payoff in the long run hurts one more? I'm simply using this particular post as an example and not really trying to pin one over the other/ I just feel that it is an honest example of logical fallacy as it is said with such accuracy rather than explorative measures.

        Two rednecks agreed that they weren't going anywhere in life and decided they should go to college to get ahead. The first redneck then went and saw an undergraduate advisor, who told him to take math, history, and logic.

        "What's 'logic'?" the first redneck asked.

        The professor answered by saying, "Let me give you an example. Do you own a weed-eater?"

        "I sure do."

        "Then I can assume, using logic, that you have a yard," replied the professor.

        "That's real good!" said the redneck.

        The professor continued, "Logic will also tell me that since you have a yard, you also own a house."

        Impressed, the redneck said, "Amazin!"

        "And since you own a house, logic dictates that you have a wife."

        "That's Betty Mae! This is incredible!" The redneck was obviously catching on.

        "Finally, since you have a wife, logically I can assume that you are heterosexual," said the professor.

        "You're absolutely right! Why that's the most fascinatin' thing I ever heard! I cain't wait to take that logic class!"

        The redneck, proud of the new world opening up to him, walked back into the hallway, where his friend was waiting.

        "So what classes are ya takin'?" asked the friend.

        "Math, history, and logic!" replied the first redneck.

        "What in tarnation is 'logic?'" asked his friend.

        "Let me give you an example. Do ya own a weed-eater?" asked the first redneck.

        "No," his friend replied.

        "You is queer, ain't ya?"

            www.youtube.com/watch

            When I was young, it seemed that life was so wonderful,
            a miracle, oh it was beautiful, magical.
            And all the birds in the trees, well they'd be singing so happily,
            joyfully, playfully watching me.
            But then they send me away to teach me how to be sensible,
            logical, responsible, practical.
            And they showed me a world where I could be so dependable,
            clinical, intellectual, cynical.
            There are times when all the world's asleep,
            the questions run too deep
            for such a simple man.
            Won't you please, please tell me what we've learned
            I know it sounds absurd
            but please tell me who I am.
            Now watch what you say or they'll be calling you a radical,
            liberal, fanatical, criminal.
            Won't you sign up your name, we'd like to feel you're
            acceptable, respectable, presentable, a vegetable!
            At night, when all the world's asleep,
            the questions run so deep
            for such a simple man.
            Won't you please, please tell me what we've learned
            I know it sounds absurd
            but please tell me who I am.

            good joke, but none of that was logic.
            guesses aren't logic.

                i believe the point in the joke is the variables taken to draw the conclusion as well as the variables NOT taken to draw the conclusion.

                  sometimes called a slippery slope.

                  The first questioner used a combination of logic and reasonable conjecture, and slowly made their way up the slope. The second sequence, the redneck jumps off a slippery slope;
                  and to an apparent wrong conclusion.

      I think that theres a lot of variables, but i think that verbal forms of information have a better chance of covering all of them than person to person.

      I'd like to cover all of the variables, and, i think that we can do so over time.

        "I'd like to cover all of the variables, and, i think that we can do so over time."

        Prom, that's a good way to go. It's also a good thing to remember that the time taken to cover all the variables can change/alter, multiple the variables at hand!!! I have in the past learned that lesson the hard way. I'm so damned analytical it's pathetic!!!

          its true that its a complicated set of issues; and that is why i am not diving straight into an attempt to just download, but taking this as it comes one step at a time.

          In some senses thats all we can do; cross bridges as we come to them.

          I'd prefer to do that together and supporting each other than to have everybody setting out
          to face the world alone.

              Principles of Rhetoric


              Rhetorical Context

              Subject — Identifies the topic about which you are writing.

              Audience — Indicates the person or persons to whom you are writing.

              Purpose — Signals your expectations for the outcome of your writing.

              Occasion — Marks the event or impulse which has prompted you to write.

              For example, you may decide to write a letter to the editor of your city's paper protesting the rezoning of your neighborhood from a "housing" zone to a "commercial" zone. In this case, your rhetorical context is as follows:

              Subject — rezoning of my neighborhood from "housing" to "commercial"
              Audience — members of my immediate community; opponents of rezoning; newspaper readers in my area
              Purpose — to persuade lawmakers to halt rezoning efforts; to encourage resistance to (and possible protest of) rezoning
              Occasion — local lawmakers' decision to rezone my community

              Or, in a business setting, you may be called on to write a grant for new computers for your office, in which case, your rhetorical context may read as follows:

              Subject — necessity of acquiring new computers for the office
              Audience — administrators of grant monies
              Purpose — to persuade administrators to give you grant money
              Occasion — office computers are inadequate for current office needs

              Logical Fallacies

              Logical fallacies are just what their name would suggest-breaks in logic. When you work to create an argument, you need to make sure that you use logic correctly. Doing so will improve your credibility as a writer and will give your readers a compelling reason to support your argument. While you will encounter countless logical fallacies in your daily life and through various media, be sure to confront them for what they are: weak rhetoric. As arguments, these reasons may seem compelling at first, but they break down over time because of their inherent faultiness. So, when you are writing, be sure to avoid the following fallacies in your own logic:

              Ad Hominem - Disparaging the character of a person rather than attacking his argument

              Bandwagon appeals - Suggesting that everyone is doing it, so why shouldn't you

              Begging the question - Restating the claim and passing it off as evidence

              Either-or - Suggesting that only two choices exist in a complex situation

              False analogies - Assuming without sufficient proof that if objects or processes are similar in some ways, then they are similar in other ways as well

              Hasty generalization - Making a broad claim made on the basis of a few occurrences

              Name calling - Linking a person, or idea, to a negative symbol

              Non sequitur (it does not follow) - Tying together two unrelated ideas-using irrelevant proof to buttress a claim

              Oversimplification - Reducing multiple causes to just one or a few

              Polarization - Exaggerating positions and groups by representing them as extreme and divisive

              Post hoc fallacy - Assuming that things that follow in time have a causal relationship

              Rationalization - Coming up with excuses or weak explanations for behavior that avoids actual causes

              Slippery slope - Assuming that if the first step is taken, other steps necessarily follow
