From Plato and Platypus Walk into a Bar...

Here’s another example of a philogag, this one a riff on the Argument from Analogy, which says that if two outcomes are similar, they must have a similar cause: A ninety-year-old man went to the doctor and said, “Doctor, my eighteen-year-old wife is expecting a baby.” The doctor said, “Let me tell you a story. A man went hunting, but instead of a gun, he picked up an umbrella by mistake. When a bear suddenly charged at the man, he picked up the umbrella, shot the bear, and killed it.” The man said, “Impossible. Someone else must have shot that bear.” The doctor said, “My point exactly!"

You couldn’t ask for a better illustration of the Argument from Analogy, a philosophical ploy currently (and erroneously) being used in the argument for Intelligent Design (i.e., if there ’s an eyeball, there must be an Eyeball-Designer-in-the-Sky.)
