  33. Danger lies before you, while safety lies behind, Two of us will help you, whichever you would find, One among us seven will let you move ahead, Another will transport the drinker back instead, Two among our number hold only nettle wine, Three of us are killers, waiting hidden in line. Choose, unless you wish to stay here forevermore, To help you in your choice, we give you these clues four: First, however slyly the poison tries to hide You will always find some on nettle wine's left side; Second, different are those who stand at either end, But if you would move onward, neither is your friend; Third, as you see clearly, all are different size, Neither dwarf nor giant holds death in their insides; Fourth, the second left and the second on the right Are twins once you taste them, though different at first sight.

  34. Fallacies • incorrect reasoning in argumentation resulting in a misconception.

  35. Ambiguity • A term that has more than one meaning • Billy is a good tennis player. • Therefore, Billy is 'good', that is to say a 'morally' good person.

  36. Hasty Generalization • Trying to prove too much from your evidence (It argues from a special case to a general rule) • Argument: Every person I've met speaks English, so it must be true that all people speak English. • Problem: Those one has met are a subset of the entire set.

  37. Ad Hominem (to the man) • Arguing against the person • "You can't believe Jack when he says the proposed policy would help the economy. He doesn't even have a job."

  38. Begging the Question • Demonstrates a conclusion by means of premises that assume that conclusion • Argument: Billy always tells the truth, I know this because he told me so. • Problem: Billy may be lying.

  39. post hoc ergo propter hoc • “After this, therefore because of this" • Since that event followed this one, that event must have been caused by this one • Argument: After Mike was vaccinated he developed autism, therefore the vaccine caused his autism. • Problem: This does not provide any evidence that the vaccine was the cause. The characteristics of autism may generally become noticeable at the age just following the typical age children receive vaccinations.

  40. Questionable Cause • Drawing an unwarranted conclusion about the cause of something • Argument: More cows die in India in the summer months. More ice cream is consumed in summer months. Therefore, the consumption of ice cream in the summer months is killing Indian cows. • Problem: It is hotter in the summer, resulting in both the death of cows and the consumption of ice cream.Also called causation versus correlation.

  41. Denying the Antecedent • If the antecedent is not true, then neither is the consequent • Argument: If it is raining outside, it must be cloudy. It is not raining outside. Therefore, it is not cloudy. • Problem: There does not have to be rain in order for there to be clouds.

  42. Appeal to the Authority • Relying on the authority of its source • Argument: The president believes that war is justifiable, therefore it must be justifiable. • Problem: The president can be wrong. 

  43. False Dilemma • Claiming there are fewer options than is actually the case • Argument: The country of the United States: Love it or leave it. • Problem: Nobody is obligated to love the country in order to be there. Nobody is obligated to leave a country based on love for such country.

  44. Appeal to emotion • It manipulates people’s emotions to get them to accept a claim as being true. Very common in politics and marketing. • Argument: I know I didn’t do the assignment and turn it in on time, but my grandmother is visiting from out of the country, and I am her only grandchild! • Problem: This claim appeals or preys upon the emotions of the listener to obtain something from him/her.

  45. Emotional language • It manipulates people’s emotions to get them to accept a claim as being true. Very common in politics and marketing. • Argument: The new PowerMangocomputer gives you the super wonderful and amazing power you need and want. If you buy one, people will desire and envy your fantastic and fabulous power. They will look up to you and wish they were as just as fantastic like you. You will know the true and unmatchable joy and glory of power. PowerMango! • Problem: This claim uses words such as wonderful, amazing, power, envy, joy, glory (and more) in order to get someone’s attention, but it doesn’t provide evidence of their claim.

  46. Accent, Unknowable fact • Accent refers to the stress placed upon a word in a sentence or a syllable in a word. Depending on it the meaning can change. Many times there is an ambiguous meaning. • Argument: Dan told me “I've never seen you looking better!” so he really liked me. • Problem: Dan could have been sarcastic or could have also mean that the other person has improved his or her image regardless whether Dan likes the other person or not.

  47. Slippery Slope • Asserting that some event must inevitably follow from another without any argument for the inevitability of the event in question. • Argument: We have to stop the tuition increase! The next thing you know, they'll be charging $40,000 a semester! • Problem: There is no evidence that the semester will increase to $40,000 based on the fact that the tuition will increase. Many more factors come to play (data, patterns, current increase, etc).

  48. Appeal to Ignorance • A fallacy based on the assumption that a statement must be true if it cannot be proved false. • Argument: There is intelligent life in outer space, for no one has been able to prove that there isn't. • Problem: Nobody knows all the confines of the outer space to conclude that there is in fact no life.

  49. Straw Man • A straw man is a component of an argument and is an informal fallacy based on misrepresentation of an opponent's position.To "attack a straw man" is to create the illusion of having refuted a proposition by substituting it with a superficially similar yet unequivalent proposition (the "straw man"), and refuting it, without ever having actually refuted the original position.. • Argument:  • Person A: Our society should spend more money helping the poor.Person • B: Studies show that handouts don't work; they just create more poverty and humiliate the recipients. That money could be better spent. • Problem: Person A never said handing out money to the poor.
