The permanent temptation of life is to confuse dreams with reality. The permanent defeat of life is when dreams are surrendered to reality.

Gödel, Escher, Bach: An Eternal Golden Braid

I had read about this really wonderful book by Douglas R. Hofstadter 'Gödel, Escher, Bach: An Eternal Golden Braid' or GEB as it is better known and have been trying to get hold of a copy. I asked a couple of my friends in the US but it didnt work out and it was not available in any of those bookshops that I asked. The other day as I was browsing thru a bookshop - as I usually do - I saw this book sitting there waiting for me and I had no hesitation in purchasing it.

I wouldnt want to go into what this book is all about, but it is a work on physics, mathematics, philosophy, artificial intelligence, computing, genetics and more (I got this from the preface of the latest edition). I am sure this is not an easy book as it deals with a lot (abstract stuff and philosophies that I may not be able to comprehend at first reading)..but am sure it is definetly worthy of the time I am going to spent on it, I am sure.

Each chapter begins with a dialogue between imaginary characters. This I guess makes it easier for lay readers like myself to get acquainted with the book before delving deeper into finding the real meaning of what the author is trying to postulate.

Here below is an imaginary conversation between a tortoise and Achilles. [It will make more sense if you can imagine pointing a camera to a TV screen and the image is displayed on the screen as a never ending system of TV screens that fall into itself... :) hehe now you are more confused than where you were]

Crab Canon by Douglas Hofstadter

Achilles and the Tortoise happen upon each other in the park one day while strolling.

TORTOISE: Good day, Mr. A.
ACHILLES: Why, same to you.
TORTOISE: So nice to run into you.
ACHILLES: That echoes my thoughts.
TORTOISE: And it's a perfect day for a walk. I think I'll be walking home soon.
ACHILLES: Oh really? I guess there's nothing better for you than walking.
TORTOISE: Incidentally, you're looking in very fine fettle these days, I must say.
ACHILLES: Thank you very much.
TORTOISE: Not at all. Here, care for one of my cigars?
ACHILLES: Oh, you are such a philistine. In this area, the Dutch contributions are of markedly inferior taste, don't you think?
TORTOISE: I disagree, in this case. But speaking of taste, I finally saw that Crab Canon by your favorite artist, M. C. Escher, in a gallery the other day, and I fully appreciate the beauty and ingenuity with which he made one single theme mesh with itself going both backwards and forwards. But I am afraid that I will always feel Bach is superior to Escher.
ACHILLES: I don't know. But one thing for certain is that I don't worry about arguments of taste. De gustibus non est disputandum.
TORTOISE: Tell me, what's it like to be your age? Is it true that one has no worries at all?
ACHILLES: To be precise, one has no frets.
TORTOISE: Oh, well, it's all the same to me.
ACHILLES: Fiddle. It makes a big difference, you know.
TORTOISE: Say, don't you play the guitar?
ACHILLES: That's my friend. He often plays, the fool. But I myself wouldn't touch a guitar with a ten-foot pole!

(Suddenly, the Crab, appearing from out of nowhere, wanders up excitedly, pointing to a rather prominent black eye.)

CRAB: Hallo! Hulloo! What's up? What's new? You see this bump, this lump? Given to me by a grump. Ho! And on such a fine day. You see, I was just idly loafing about the park when up lumbers this giant fellow from Warsaw — a colossal bear of a man — playing a lute. He was three meters tall, if I'm a day. I mosey on up to the chap, reach skyward and manage to tap him on the knee, saying, "Pardon me, sir, but you are Pole-luting our park with your mazurkas." But WOW! he had no sense of humor — not a bit, not a wit — and POW! — he lets loose and belts me one, smack in the eye! Were it in my nature, I would crab up a storm, but in the time-honored tradition of my species, I backed off. After all, when we walk forwards, we move backwards. It's in our genes, you know, turning round and round. That reminds me — I've always wondered, "Which came first — the Crab, or the Gene?" That is to say, "Which came last — the Gene or the Crab?" I'm always turning things round and round, you know. It's in our genes, after all. When we walk backwards, we move forwards. Ah me, oh my! I must lope along on my merry way — so off I go on such a fine day. Sing "ho!" for the life of a Crab! TATA! ¡Olé!

(And he disappears as suddenly as he arrived.)

TORTOISE: That's my good friend. He often plays the fool. But I myself wouldn't touch a ten-foot Pole with a guitar!
ACHILLES: Say, don't you play the guitar?
TORTOISE: Fiddle. It makes a big difference, you know.
ACHILLES: Oh, well, it's all the same to me.
TORTOISE: To be precise, one has no frets.
ACHILLES: Tell me, what's it like to be your age? Is it true that one has no worries at all?
TORTOISE: I don't know, but one thing for certain is that I don't worry about arguments of taste. Disputandum non est de gustibus.
ACHILLES: I disagree, in this case. But speaking of taste, I finally heard that Crab Canon by your favorite composer, J.S. Bach, in a concert the other day, and I fully appreciate the beauty and ingenuity with which he made one single theme mesh with itself going both backwards and forwards. But I'm afraid I will always feel Escher is superior to Bach.
TORTOISE: Oh, you are such a philistine. In this area, the Dutch contributions are of markedly inferior taste, don't you think?
ACHILLES: Not at all. Here, care for one of my cigars?
TORTOISE: Thank you very much.
ACHILLES: Incidentally, you're looking in very fine fettle these days, I must say.
TORTOISE: Oh really? I guess there's nothing better for you than walking.
ACHILLES: And it's a perfect day for a walk. I think I'll be walking home soon.
TORTOISE: That echoes my thoughs.
ACHILLES: So nice to run into you.
TORTOISE: Why, same to you.
ACHILLES: Good day, Mr. T.
