About this Book

Print Excerpt


In the years that followed, I became increasingly less impressed with my own intelligence. My perceived place on the bell curve drifted farther and farther to the left. I went from being, in my mind, much smarter than my dad to a little smarter, to just as smart, and then, finally -- if I had to guess when, it'd be somewhere in my freshman or sophomore year at college -- less smart than my dad, the author of those imposing twenty-four books.

In retrospect, the revelation about my intelligence -- the one inspired by the studious Hasidic boys -- wasn't exactly the product of flawless logic. There's not a perfect correlation between hours of reading and intelligence. Perhaps there's very little correlation at all. Of course, I do realize I'm committing the same fallacy right now, twenty-three years later. Deep down, I know that reading the encyclopedia and jamming my brain full of facts won't necessarily allow me to reclaim my title as the smartest person alive. I know my quest is a bit of a lark. I know it's got a whiff -- or maybe more than a whiff -- of the absurd.

And just in case I didn't know, I'm constantly being told this by friends and family. My aunt Marti, who lives in Berkeley and is always ready to voice her skepticism, whether it's about our phallocentric government or our reliance on oppressive Western medicine, confronted me in a phone call the other day.

"Now, why are you reading the encyclopedia again?"

"I'm trying to become the smartest man in the world."

"And how are you defining intelligence? Just the amount of information you have?"

"Yup."

"Well, that's not very intelligent."

"Well, I haven't gotten to the letter I."

It's an easy response, but there's something to it. I'm not so deluded that I think I'll gain one IQ point for every thousand pages. I don't honestly think that the folks from the MacArthur genius grant will be kicking down my door. But I also believe that there is some link between knowledge and intelligence. Maybe knowledge is the fuel and intelligence is the car? Maybe facts are the flying buttresses and intelligence is the cathedral? I don't know the exact relation. But I'm sure the Britannica, somewhere in those 44 million words, will help me figure it out.

 

augury

You can predict the future based on dice (cleromancy), dots on paper (geomancy), fire and smoke (pyromancy), entrails of sacrificed animals (haruspicy), animal livers (hepatoscopy), or shoulder blades of animals (scapulimancy). They had me up until the crazy shoulder blades part.

 

Aztec

The A's have been lousy with Aztecs. They popped up under all sorts of headings, including American Peoples, Arts of Native and Alcohol and Drug Consumption (they called magic mushrooms "God's flesh"). And here they are again, under plain old Aztec. Thanks to the Britannica, I now know the Aztecs prophesied the destruction of the earth followed by an age when humans become monkeys. Hey, that's the plot of Planet of the Apes! Damn you, Hollywood! You stole the idea from the Aztecs. Damn you to hell!

I polish off the monkey-fixated Aztecs, and just like that, I'm done with the A's. It's been two weeks, and I am now one twenty-sixth of my way to the summit. I have absorbed 3.8 percent of all the knowledge in the world. I slam my Britannica shut and do a little touchdown dance. Yes! I am the alpha male.

And yet, do I feel smarter? Have I proved my skeptical aunt Marti wrong yet? Well, I do know a lot more information, but in a way, I'm feeling more insecure than ever. I'm worried I'm not intelligent enough to process all my data into some coherent conclusion or worldview. I'm worried I'm not focusing on the right things. Take Aristotle. Here's one of the great philosophers of all time. I should be drinking in his theories on morality and epistemology. Instead, I'm fascinated by Aristotle's obscure maxim about marriage: that men should be thirty-seven and women should be eighteen when they take their vows. Aristotle came up with that theory because -- now here's an odd coincidence -- when he was thirty-seven he married an eighteen-year-old woman. I like that he rationalized his dirty-old-man behavior with a grand philosophical statement. There are a lot of Aristotelians in Hollywood, I chuckle to myself. So that's the profound conclusion I draw from the essay on Aristotle. That he likes young ladies.
