This question was just as tricky as the old riddle of the chicken and the egg. There would be no chicken without the egg, and no egg without the chicken. Was it really just as complicated to figure out whether the chicken or the “idea” chicken came first? Sophie understood what Plato meant. He meant that the “idea” chicken had existed in the world of ideas long before chickens existed in the sensory world. According to Plato, the soul had “seen” the “idea” chicken before it took up residence in a body. But wasn’t this just where Sophie thought Plato must be mistaken? How could a person who had never seen a live chicken or a picture of a chicken ever have any “idea” of a chicken? Which brought her to the next question:
Are we born with innate “ideas”? Most unlikely, thought Sophie. She could hardly imagine a newborn baby being especially well equipped with ideas. One could obviously never be sure, because the fact that the baby had no language did not necessarily mean that it had no ideas in its head. But surely we have to see things in the world before we can know anything about them.
“What is the difference between a plant, an animal, and a human?” Sophie could immediately see very clear differences.
For instance, she did not think a plant had a very complicated emotional life. Who had ever heard of a bluebell with a broken heart? A plant grows, takes nourishment, and produces seeds so that it can reproduce itself. That’s about all one could say about plants. Sophie concluded that everything that applied to plants also applied to animals and humans. But animals had other attributes as well. They could move, for example. (When did a rose ever run a marathon?) It was a bit harder to point to any differences between animals and humans. Humans could think, but couldn’t animals do so as well? Sophie was convinced that her cat Sherekan could think. At least, it could be very calculating. But could it reflect on philosophical questions? Could a cat speculate about the difference between a plant, an animal, and a human? Hardly! A cat could probably be either contented or unhappy, but did it ever ask itself if there was a God or whether it had an immortal soul? Sophie thought that was extremely doubtful. But the same problem was raised here as with the baby and the innate ideas. It was just as difficult to talk to a cat about such questions as it would be to discuss them with a baby.
“Why does it rain?” Sophie shrugged her shoulders. It probably rains because seawater evaporates and the clouds condense into raindrops. Hadn’t she learnt that in the third grade? Of course, one could always say that it rains so that plants and animals can grow. But was that true? Had a shower any actual purpose?
The last question definitely had something to do with purpose: “What does it take to live a good life?”
The philosopher had written something about this quite early on in the course. Everybody needs food, warmth, love, and care. Such basics were the primary condition for a good life, at any rate. Then he had pointed out that people also needed to find answers to certain philosophical questions. It was probably also quite important to have a job you liked. If you hated traffic, for instance, you would not be very happy as a taxi driver. And if you hated doing homework it would probably be a bad idea to become a teacher. Sophie loved animals and wanted to be a vet. But in any case she didn’t think it was necessary to win a million in the lottery to live a good life.
Quite the opposite, more likely. There was a saying:
The devil finds work for idle hands.
Sophie stayed in her room until her mother called her down to a big midday meal. She had prepared sirloin steak and baked potatoes. There were cloudberries and cream for dessert.
They talked about all kinds of things. Sophie’s mother asked her how she wanted to celebrate her fifteenth birthday. It was only a few weeks away.
Sophie shrugged.
“Aren’t you going to invite anyone? I mean, don’t you want to have a party?”
“Maybe.”
“We could ask Martha and Anne Marie ... and Helen. And Joanna, of course. And Jeremy, perhaps. But that’s for you to decide. I remember my own fifteenth birthday so clearly, you know. It doesn’t seem all that long ago. I felt I was already quite grown up. Isn’t it odd, Sophie! I don’t feel I have changed at all since then.”
“You haven’t. Nothing changes. You have just developed, gotten older...”
“Mm ... that was a very grownup thing to say. I just think it’s all happened so very quickly.”
Aristotle
...a meticulous organizer who wanted to clarify our concepts …
While her mother was taking her afternoon nap, Sophie went down to the den. She had put a lump of sugar in the pink envelope and written “To Alberto” on the outside.
There was no new letter, but after a few minutes Sophie heard the dog approaching.
“Hermes!” she called, and the next moment he had pushed his way into the den with a big brown envelope in his mouth.
“Good boy!” Sophie put her arm around the dog, which was snorting and snuffling like a walrus. She took the pink envelope with the lump of sugar and put it in the dog’s mouth. He crawled through the hedge and made off into the woods again.
Sophie opened the big envelope apprehensively, wondering whether it would contain anything about the cabin and the boat.
It contained the usual typed pages held together with a paperclip. But there was also a loose page inside. On it was written:
Dear Miss Sleuth, or, to be more exact, Miss Burglar. The case has already been handed over to the police.
Not really. No, I’m not angry. If you are just as curious when it comes to discovering answers to the riddles of philosophy, I’d say your adventure was very promising. It’s just a little annoying that I’ll have to move now. Still, I have no one to blame but myself, I suppose. I might have known you were a person who would always want to get to the bottom of things.
Greetings, Alberto
Sophie was relieved. So he was not angry after all. But why would he have to move?
She took the papers and ran up to her room. It would be prudent to be in the house when her mother woke up. Lying comfortably on her bed, she began to read about Aristotle.
PHILOSOPHER AND SCIENTIST
Dear Sophie: You were probably astonished by Plato’s theory or ideas. You are not the only one! I do not know whether you swallowed the whole thing—hook, line, and sinker—or whether you had any critical comments. But if you did have, you can be sure that the self-same criticism was raised by Aristotle (384-322 B.C.), who was a pupil at Plato’s Academy for almost twenty years.
Aristotle was not a native of Athens. He was born in Macedonia and came to Plato’s Academy when Plato was 61. Aristotle’s father was a respected physician— and therefore a scientist. This background already tells us something about Aristotle’s philosophic project. What he was most interested in was nature study. He was not only the last of the great Greek philosophers, he was Europe’s first great biologist.
Taking it to extremes, we could say that Plato was so engrossed in his eternal forms, or “ideas,” that he took very little notice of the changes in nature. Aristotle, on the other hand, was preoccupied with just these changes— or with what we nowadays describe as natural processes.
To exaggerate even more, we could say that Plato turned his back on the sensory world and shut his eyes to everything we see around us. (He wanted to escape from the cave and look out over the eternal world of ideas!) Aristotle did the opposite: he got down on all fours and studied frogs and fish, anemones and poppies.
While Plato used his reason, Aristotle used his senses as well.
We find decisive differences between the two, not least in their writing. Plato was a poet and mythologist; Aristotle’s writings were as dry and precise as an encyclopedia. On the other hand, much of what he wrote was based on up-to-the-minute field studies.
Records from antiquity refer to 170 titles supposedly written by Aristotle. Of these, 47 are preserved. These are not complete books; they consist largely of lecture notes. In his time, philosophy was still mainly an oral activity.
The significance of Aristotle in European culture is due not least to the fact that he created the terminology that scientists use today. He was the great organizer who founded and classified the various sciences.
Since Aristotle wrote on all the sciences, I will limit myself to some of the most important areas. Now that I have told you such a lot about Plato, you must start by hearing how Aristotle refuted Plato’s theory of ideas. Later
