Solitude

This is an SAT practice essay I wrote a few weeks ago.

***********

In Daniel Defoe’s novel Robinson Crusoe, the island where the title character is trapped is, for the first part of the story, uninhabited. Crusoe is alone with himself and his thoughts. Having no one to talk to, he begins to talk to himself, asking and trying to answer questions like “Why?” This introspection gradually helps him understand his past, a possible purpose for his shipwreck, and even a little more about how God is working in his life.

In this ultimate solitude Crusoe is better able to develop an objective worldview. There is nobody to interrupt or argue with him. Emily Dickenson, a Romantic-era poet, stayed concealed in her home with little outside contact, and her poems are deeply thoughtful and even, at times, theological. Like Crusoe, she found her worldview by herself.

There is a downside to a sealed environment, though. Mark Twain wrote a short story called “The Man Who Corrupted Hadleyburg,” in which the inhabitants of Hadleyburg protect themselves so carefully from any dishonesty that when one man is able to sneak a temptation into the city, every person in the town falls to it in a matter of weeks. Untested faith is often blind and useless.

Perhaps introspection and solitude are necessary to develop ideas and achieve goals, but then everything must be tested in the ordinary world. An experiment that works in a closed system may quite possibly crash and burn outside. Nothing will past the test of time if it cannot first pass the tests of experience, thought and argument. And worthwhile argument is seldom put forward when a person is talking to himself.

Friendship: Definition Paragraph

"Friendship is one of the most satisfying things in the world," says Wilbur, a pig from the book Charlotte's Web. But just what is friendship? Some synonyms are love, affinity, or unity. Friendship is the opposite of hatred or enmity. A similar term is loyalty. When combined, friendship and loyalty can do amazing things. In Lord of the Rings, the Fellowship was chosen more for loyalty and friendship than power or strength. The reason for this was that good was fighting against evil, love against hate, and unity against enmity. Friendship is not only one of the most satisfying things in the world, but also one of the most amazing.

"Ours is Not to Reason Why - Just Invert and Multiply!"

Today's math lesson, courtesy of the VideoText program, cleared up what has always been one of math's mysterious mysteries - that mystifying "invert-and-multiply" rule.

If you want to divide 4/5 by 7/8, then you would think that "all you do is multipy 4/5 by 8/7". But how in the world did we get 8/7 out of 7/8?

4/5 divided by 7/8 means 4/5 / 7/8. We have to get a one at the bottom, to simplify this strange and complex fraction. So we multiply 7/8 by its reciprocal - 8/7 - to get a one.

Does anyone understand why
We must invert and multiply?

It's a simplification of a simple process. Anyone who's worked with fractions knows that when you multiply the bottom of a fraction by any number, you have to do the top, too! So we multiply 4/5 by 8/7 too - tada! The answer is 32/35.

This was such an exciting discovery I just had to share it with someone. So if you're out there in the cyberworld and you've always wondered why we "never reason why - just invert and multiply"...

are you excited too?
