Life of Pi

suffering left me sad and gloomy.
     
    Academic study and the steady, mindful practice of religion slowly wrought me back to life. I have kept up with what some people would consider my strange religious practices. After one year of high school, I attended the University of Toronto and took a double-major Bachelor's degree. My majors were religious studies and zoology. My fourth-year thesis for religious studies concerned certain aspects of the cosmogony theory of Isaac Luria, the great sixteenth-century Kabbalist from Safed. My zoology thesis was a functional analysis of the thyroid gland of the three-toed sloth. I chose the sloth because its demeanour—calm, quiet and introspective—did something to soothe my shattered self.
     
    There are two-toed sloths and there are three-toed sloths, the case being determined by the forepaws of the animals, since all sloths have three claws on their hind paws. I had the great luck one summer of studying the three-toed sloth in situ in the equatorial jungles of Brazil. It is a highly intriguing creature. Its only real habit is indolence. It sleeps or rests on average twenty hours a day. Our team tested the sleep habits of five wild three-toed sloths by placing on their heads, in the early evening after they had fallen asleep, bright red plastic dishes filled with water. We found them still in place late the next morning, the water of the dishes swarming with insects. The sloth is at its busiest at sunset, using the word busy here in the most relaxed sense. It moves along the bough of a tree in its characteristic upside-down position at the speed of roughly 400 metres an hour. On the ground, it crawls to its next tree at the rate of 250 metres an hour, when motivated, which is 440 times slower than a motivated cheetah. Unmotivated, it covers four to five metres in an hour.
     
    The three-toed sloth is not well informed about the outside world. On a scale of 2 to 10, where 2 represents unusual dullness and 10 extreme acuity, Beebe (1926) gave the sloths senses of taste, touch, sight and hearing a rating of 2, and its sense of smell a rating of 3. If you come upon a sleeping three-toed sloth in the wild, two or three nudges should suffice to awaken it; it will then look sleepily in every direction but yours. Why it should look about is uncertain since the sloth sees everything in a Magoo-like blur. As for hearing, the sloth is not so much deaf as uninterested in sound. Beebe reported that firing guns next to sleeping or feeding sloths elicited little reaction. And the sloth's slightly better sense of smell should not be overestimated. They are said to be able to sniff and avoid decayed branches, but Bullock (1968) reported that sloths fall to the ground clinging to decayed branches "often".
     
    How does it survive, you might ask.
     
    Precisely by being so slow. Sleepiness and slothfulness keep it out of harm's way, away from the notice of jaguars, ocelots, harpy eagles and anacondas. A sloth's hairs shelter an algae that is brown during the dry season and green during the wet season, so the animal blends in with the surrounding moss and foliage and looks like a nest of white ants or of squirrels, or like nothing at all but part of a tree.
     
    The three-toed sloth lives a peaceful, vegetarian life in perfect harmony with its environment. "A good-natured smile is forever on its lips," reported Tirler (1966). I have seen that smile with my own eyes. I am not one given to projecting human traits and emotions onto animals, but many a time during that month in Brazil, looking up at sloths in repose, I felt I was in the presence of upside-down yogis deep in meditation or hermits deep in prayer, wise beings whose intense imaginative lives were beyond the reach of my scientific probing.
     
    Sometimes I got my majors mixed up. A number of my fellow religious-studies students—muddled agnostics who didn't know which way was up, who were in the thrall of reason, that fool's gold for the bright—reminded me of the three-toed sloth; and the three-toed sloth, such a beautiful example of the miracle of life, reminded me of God.
     
    I never had problems with my fellow scientists. Scientists are a friendly, atheistic, hard-working, beer-drinking lot whose minds are preoccupied with sex, chess and baseball when they are not preoccupied with science.
     
    I was a very good student, if I may say so myself. I was tops at St. Michael's College four years in a row. I got every possible student
