Which reminded me of a joke I read recently. I think I have finally got a sort of understanding of formal logic, after reading a short, funny book called You've Got to Be Kidding; How Jokes Can Help You Think. I'd really recommend this book as an enjoyable introduction to critical thinking. I laughed all the way through and drove my family mad constantly telling them jokes and explaining the logic point behind them.
the joke was about a bar, but it could apply to public transport.
A guy goes into a bar with a German shepherd dog and sits down at the counter. The bartender says, "You can't bring that German shepherd in here! Dogs ain't allowed!" The guy replies, "But this is a Seeing Eye dog." The bartender says, "Well, in that case, I guess it can stay." After awhile the guy and the German shepherd get up to leave. As they are heading out the door, another guy with a Chihuahua is coming in, and the first guy says, "The bartender won't like you bringing a dog in here, but if you tell him it's a Seeing Eye dog, maybe he'll let you stay." The second guy looks dubiously at his tiny Chihuahua, thinks a few seconds, thanks the guy, and goes in. The bartender says, "Hey! You can't bring that chihuahua in here!" The man stares straight ahead and exclaims, "What! They sold me a Chihuahua?!"And you may be wondering what you could learn about critical thinking from this joke...Well, you'll have to buy the book.
