Things I found inside my mind.

My Brain Made Me Do It

Are we truly in control of our own actions, or are they are really determined by our genes and environment? Are our brains really just machines operating according to the laws of physics? Is our free will nothing more than an illusion? And if it is, how can we be morally responsible for anything?

These questions are just about the biggest and most difficult questions we can think about. I know what the answers are, but if you don’t, it would be worth your while to read the first half of “My Brain Made Me Do It” by Eliezer Sternberg. Sternberg raises the questions, discusses some of the evidence and research and identifies some current approaches. It’s a good exploration of the topic and it does get you thinking.

How to argue

When you’re arguing with other people, it’s all too easy to disagree with what you think they are saying. It’s better to base your argument on what they are actually saying. But best of all is to argue with what they think they are saying.

The Art of Always Being Right — Arthur Schopenhauer

This book is not really about being right. It’s about winning arguments, even when you’re wrong. The 38 tactics include such classics as “Use your opponent’s views”, “Beg the question” and the ultimate: “Become personal, insulting, rude”. You’ll recognise these from many annoying and unsatisfying arguments you’ve had. This book helps you avoid them, and if necessary, use them yourself. Very useful, and all based on “the natural baseness of human nature”. Perhaps it’s best not to dwell on that.

Thanks to Wikisource and the wonders of copyright law, you can read The Art of Always Being Right online for free.

God is Not Great — Christopher Hitchens

Organised religion is a pernicious anachronism that should be abolished, according to Christopher Hitchens. His book is subtitled “How religion poisons everything” in case there was any doubt about his position. Organised religions are pretty much indefensible anyway, but his arguments are still worth reading — I learned a few interesting bits of history. And it’s bracing to see so many dogmas held up in such a cold and unflattering light.

God is not Great takes iconoclasm to new heights. Hitchens heaps scorn on the usual zealots, from Osama bin Laden to various Popes (including the current one). But his targets cover the full spectrum of celebrity, from the sublime (Mother Theresa, M. K. Gandhi, the Dalai Lama) to the ridiculous (Mel Gibson is memorably described as an “Australian fascist and ham actor”). The only famous exception is Martin Luther King, Jr, who manages to come out looking like a decent (if flawed) human being.

I enjoyed reading God is not Great, but I think it does miss the point a bit. In the conflict between Reason and Faith, Reason wins easily; but that’s because Faith isn’t playing the game. Some say that if people believe religious dogmas even in the face of overwhelming evidence to the contrary, then this simply confirms how marvellously strong their faith is. You just can’t use logic against this kind of position, but that what Hitchens tries to do. This approach only seems to work here because he is preaching to the converted. Or perhaps I should say unconverted.

Lucky Numbers are Unlucky

If you ever buy a lotto ticket, or bet on horses or any other such game where the aim is to select winning numbers, don’t choose the numbers yourself. If you pick your own special “lucky numbers” once, you’re stuck with them for the rest of your life.

When choosing the numbers, you might think it’s fun to pick significant numbers such as your family’s birthdays, even if you don’t win. But you won’t find it so much fun if you don’t buy a ticket next week and the numbers come up then. Or if they come up the next month, or year, or ten years after that. And since you thoughtfully picked special numbers, you’ll never forget them — no matter when they come up, you’ll know you missed out, and you’ll spend the rest of your life lamenting. “If only I’d bought a ticket this week, I would have won and I’d be able to buy that yacht/university degree/TV station/kidney that I always wanted.”

The only safe procedure is to select your numbers randomly. As a bonus, if you don’t win (and let’s face it: you won’t), you can blame fate for your misfortune rather than having to blame yourself for picking the wrong numbers.

Child-safe swear words

When you have small children (I imagine), you have to be careful what you say around them. They are just learning to speak and may seize on any word and repeat it unpredictably. This happened to a friend of mine who somehow managed to say “scrotum” within earshot of his small son. The word subsequently turned up in various inappropriate situations, to general hilarity. I’m sure this happens thousands of times a day, all over the world.

I’m not sure of the context for my friend’s “scrotum” — when you’re annoyed, all kinds of expletives can just pop out. Of course, this won’t be a problem for me, because I don’t know any rude words (except “scrotum”, and I will be careful to avoid using it gratuitously). But for the rest of you, I am compiling a list of swear words that you can safely say in front of even the most parrot-like three-year-old.

My Giddy Aunt! This sounds like something out of Gilbert & Sullivan, or possibly P. G. Wodehouse. Probably not so good if you actually do have an aunt who is giddy.

The road less travelled

Suppose there are two roads between two points. One road is free to use, the other has a toll. The one with the toll will, of course, be less crowded. So road users can travel for free, or they can pay extra to get there quicker.

The interesting thing is that this works regardless of the other differences between the roads. The toll road might actually be wider or narrower, longer or shorter than the free one. But as long as the roads are sufficiently busy, the journey will always be quicker on the toll road.

I was thinking about applying this idea to supermarket queues. Supermarkets could set aside one or two checkout lanes that have a charge of $1 to use. If you’re in a hurry, you can pay the extra money; the queue will always be shorter.
