  1. review some important examples of paradox How do we interpret “reality”. What models do we build to simplify, generalize, and organize the complex data of experience?

  2. Chinese tale from the fourth century B.C. Chuang-tzu was a man who dreamt he was a butterfly , and then awoke to wonder if he was a butterfly dreaming he was a man.

  3. Is this slide show “real” - or are you dreaming that you are sitting in paradox class watching a slide show?

  5. The hare and the turtle decide to run a race

  6. Because I run twice as fast as you do, I will give you a half mile head start Thanks!

  7. In the time that it takes the hare to run the ½ mile that separates him from the turtle, the turtle has progressed another ¼ mile.

  8. In the time that it takes the hare to run the ¼ mile that separates him from the turtle, the turtle has progressed another 1/8 mile.

  9. In the time that it takes the hare to run the 1/8 mile that separates him from the turtle, the turtle has progressed another 1/16 mile.

  10. No matter how quickly the hare runs, during the time it takes him to reach the turtles current position, the turtle will have moved ahead. Can the swift hare ever catch the plodding turtle?

  19. drug A drug B 1 out of 5 =20% of the men treated with drug A are cured. 2 out of 8 =25% of the men treated with drug B are cured.

  20. drug A drug B 1 out of 5 =20% of the men treated with drug A are cured. 2 out of 8 =25% of the men treated with drug B are cured. 4 out of 10 =40% of the women treated with drug A are cured.

  22. drug A drug B 1 out of 5 =20% of the men treated with drug A are cured. 2 out of 8 =25% of the men treated with drug B are cured. A higher percentage of men are cured with B 4 out of 10 =40% of the women treated with drug A are cured. 1 out of 2 =50% of the women treated with drug B are cured. A higher percentage of women are cured with B

  23. drug A drug B 1 out of 5 =20% of the men treated with drug A are cured. 2 out of 8 =25% of the men treated with drug B are cured. 4 out of 10 =40% of the women treated with drug A are cured. 1 out of 2 =50% of the women treated with drug B are cured.

  25. drug A drug B 5 out of 15 = 33 1/3 % of people treated with A are cured 3 out of 10 = 30 % of people treated with B are cured

  26. drug A drug B 5 out of 15 = 33 1/3 % of people treated with A are cured 3 out of 10 = 30 % of people treated with B are cured A higher percentage of people are cured with A

  32. some paradoxes in Aristotelian logic

  33. That duck is lying! What he says is true

  34. proof that Santa Claus exists

  35. T T F T T F F T “If John studies then he will get an A.” T F T F

  36. T T F T T F F T “If then .” T F T F the model

  37. T T F T T F F T “If this statement is true then Santa Claus exisits .” T F T F

  38. T T F T T F F T This statement “If this statement is true then Santa Claus exisits .” T F T F

  39. T T F T T F F T This statement “If this statement is true then Santa Claus exisits .” T The only conditions under which this statement is FALSE F T F

  40. T T F T T F F T This statement “If this statement is true then Santa Claus exisits .” T The only conditions under which this statement is FALSE F T F a contradiction

  41. T T T F T T F F must be TRUE This statement “If this statement is true then Santa Claus exisits .” T F T F So Santa Claus exists!

  42. Of course, the exact same reasoning can be used to prove that Santa Claus does NOT exist!
