March 28:  Thought Experiment Day

Today is the birthday of Daniel C. Dennett, American philosopher, writer, and cognitive scientist, who was born in Boston, Massachusetts in 1942.

One specific category of thinking tools used frequently by philosophers is thought experiments.  Dennett calls them intuition pumps (a term he coined in 1980), the philosophical equivalent of Aesop’s fables.  These thought experiments present vivid vignettes, hypothetical situations that allow thinkers to explore and examine ideas.  Like parables, thought experiments are micro-narratives, making ideas more practical and easy to remember (1).

One ancient thought experiment comes from Plato’s The Republic:  

The Allegory of the Cave

Imagine three prisoners who have been chained in a cave their entire lives.  They are chained in such a way that all they can see is the wall of the cave in front of them.  Behind them, there is a fire and a raised walkway. As people walk along the walkway carrying things like books, animals, and plants, the prisoner sees nothing but the shadows of the people and the items they carry cast on the wall in front of them.  Because the prisoners see only the shadows, these shadows become their reality. When they see a shadow of a book, for example, they take the shadow as the real object, since it is all they know.

Imagine that one of the prisoners escapes his chains and leaves the cave.  Leaving the darkness of the cave, he is first blinded by the light. As his eyes slowly adjust and as he becomes more used to his new surroundings, he begins to realize that his former understanding of the world was wrong.  Returning to the cave, the enlightened prisoner tells the other prisoners what he has learned of the real world. The others, noticing that the returning prisoner is groping around in the darkness as his eyes readjust to the darkness, think he is insane. They can’t imagine any other reality but the shadows they see before them, and they threaten to murder anyone who would drag them out of the cave or annoy them with supposed insight into what a “real” book or a “real” tree actually looks like (2).

Plato’s Cave allows us to address and discuss the abstract ideas of knowledge versus ignorance and perception versus reality.  It doesn’t just tell us that philosophy will improve our lives; instead, it shows us: most of us live our life watching the shadows in the cave; philosophy and education, however, offer us a way out of the darkness and into the light of reason.

Today’s Challenge:  Pump Up Your Tired Thinking

What are some examples of philosophical questions that might be debated about universal topics, such as the nature of reality, of knowledge, of morality, of consciousness, of free will, or of government?  Research a specific thought experiment (see the list below).  Summarize the key elements of the thought experiment in your own words; then, discuss what specific philosophical ideas the thought experiment addresses.

The Whimsical Jailer, The Nefarious Neurosurgeon, Infinite Monkey Theorem, Buridan’s Ass, The Brain in a Vat, The Trolley Problem, Schrodinger’s Cat, Ship of Theseus, The Chinese Room, The Lady or the Tiger

March 27:  Similes for Life Day

On this day in 1995, the film Forrest Gump won best picture at the 99th Academy Awards.  The movie was based on the 1986 novel of the same name, written by Winston Groom.

A man wearing a white suit is sitting on the right side of the bench and is looking to his left while resting his hands on both sides of him on the bench. A suitcase is sitting on the ground, and the man is wearing tennis shoes. At the top left of the image is the film's tagline and title and at the bottom is the release date and production credits.Groom grew up in Alabama, and many of his books, including Forrest Gump, draw on his experiences in Vietnam, where he served in the U.S. Army from 1966-1967.  Before Winston’s novel was adapted for the big screen, it was not a big seller; however, after the film came out in 1994, the book became a bestseller.  Winston’s 1988 novel Gone The Sun won the Pulitzer Prize (1).

Winston’s best-known character is the slow-witted southerner Forrest Gump, who faces his life with childlike innocence and optimism.  Almost as memorable as the character himself is his iconic simile — a quotation that became one of the most famous lines in movie history:  “Life is like a box of chocolates; you never know what you’re going to get.”

Today’s Challenge:  Life is Like a Writing Assignment . . . .

What concrete noun presents the best figurative comparison for life?  Notice how each of the similes for life below follow the same basic formula.  Like Forrest Gump’s simile, they begin with a simple comparison, using “like” and a concrete noun.  Each writer then follows the comparison with elaboration, explaining how or why life is like the concrete noun.

Life is like a ten-speed bicycle.  Most of us have gears we never use. -Charles M. Schulz

Life is like a play; it’s not the length, but the excellence of the acting that matters. -Seneca the Younger

Life is like a dog-sled team.  If you ain’t the lead dog, the scenery never changes. -Lewis Grizzard

Write your own simile for life by brainstorming some possible concrete nouns. Use the list below to get you started.

a sandwich, a sandbox, a symphony, a slug, a salad, a game of checkers, a battle, a bruised banana, a lunchbox, a race, a book, a fire, an alphabet, a cat, a hammer

Feel free to modify your nouns with other words that make them more specific; for example, life might be a “relay race,” “a sprinting race,” or “long-distance race.”

Use the following template to help you construct your simile:

Life is like [concrete noun] _______; [Explain how, why, or under what circumstances life is like this] ______________.

Quotation of the Day:  Life is like riding a bicycle.  To keep your balance you must keep moving. -Albert Einstein
