Thinking Like a Rat

Richard Feynman

All experiments in psychology are not of this [cargo cult] type, however. For example there have been many experiments running rats through all kinds of mazes, and so on—with little clear result. But in 1937 a man named Young did a very interesting one. He had a long corridor with doors all along one side where the rats came in, and doors along the other side where the food was. He wanted to see if he could train rats to go to the third door down from wherever he started them off. No. The rats went immediately to the door where the food had been the time before.

The question was, how did the rats know, because the corridor was so beautifully built and so uniform, that this was the same door as before? Obviously there was something about the door that was different from the other doors. So he painted the doors very carefully, arranging the textures on the faces of the doors exactly the same. Still the rats could tell. Then he thought maybe they were smelling the food, so he used chemicals to change the smell after each run. Still the rats could tell. Then he realized the rats might be able to tell by seeing the lights and the arrangement in the laboratory like any commonsense person. So he covered the corridor, and still the rats could tell.

He finally found that they could tell by the way the floor sounded when they ran over it. And he could only fix that by putting his corridor in sand. So he covered one after another of all possible clues and finally was able to fool the rats so that they had to learn to go to the third door. If he relaxed any of his conditions, the rats could tell.

Now, from a scientific standpoint, that is an A-number-one experiment. That is the experiment that makes rat-running experiments sensible, because it uncovers the clues that the rat is really using — not what you think it’s using. And that is the experiment that tells exactly what conditions you have to use in order to be careful and control everything in an experiment with rat-running.

I looked into the subsequent history of this research. The next experiment, and the one after that, never referred to Mr. Young. They never used any of his criteria of putting the corridor on sand, or of being very careful. They just went right on running rats in the same old way, and paid no attention to the great discoveries of Mr. Young, and his papers are not referred to, because he didn’t discover anything about rats. In fact, he discovered all the things you have to do to discover something about rats. But not paying attention to experiments like that is a characteristic of cargo cult science.—Richard Feynman, 1974 Commencement Address

 

Bougainville on the Indians of the East

Louis Antoine de Bougainville

I see no difference in the dress, ornaments, dances, and songs of the various western nations. They go naked, excepting a strip of cloth passed through a belt, and paint themselves black, red, blue, and other colors. Their heads are shaved and adorned with bunches of feathers, and they wear rings of brass wire in their ears. They wear beaver-skin blankets, and carry lances, bows and arrows, and quivers made of the skins of beasts. For the rest they are straight, well made, and generally very tall. Their religion is brute paganism. I will say it once for all, one must be the slave of these savages, listen to them day and night, in council and in private, whenever the fancy takes them, or whenever a dream, a fit of the vapors, or their perpetual craving for brandy, gets possession of them; besides which they are always wanting something for their equipment, arms or toilet, and the general of the army must give written orders for the smallest trifle,—an eternal, wearisome detail, of which one has no idea in Europe.—Louis Antoine de Bougainville as quoted in Francis Parkman’s Montcalm and Wolfe

 

A Yellow Rose

Borges

Neither that afternoon nor the next did the illustrious Giambattista Marino die, he whom the unanimous mouths of Fame—to use an image dear to him—proclaimed as the new Homer and the new Dante. But the still, noiseless fact that took place then was in reality the last event of his life. Laden with years and with glory, he lay dying on a huge Spanish bed with carved bedposts. It is not hard to imagine a serene balcony a few steps away, facing the west, and, below, marble and laurels and a garden whose various levels are duplicated in a rectangle of water. A woman has placed in a goblet a yellow rose. The man murmurs the inevitable lines that now, to tell the truth, bore even him a little:

Purple of the garden, pomp of the meadow,
Gem of spring, April’s eye …

Then the revelation occurred: Marino saw the rose as Adam might have seen it in Paradise, and he thought that the rose was to be found in its own eternity and not in his words; and that we may mention or allude to a thing, but not express it; and that the tall, proud volumes casting a golden shadow in a corner were not—as his vanity had dreamed—a mirror of the world, but rather one thing more added to the world.

Marino achieved this illumination on the eve of his death, and Homer and Dante may have achieved it as well.—Jorge Luis Borges, El Hacedor

Do Not Pity Me

You must not pity me because my sixtieth year finds me still astonished. To be astonished is one of the surest ways of not growing old too quickly.—Colette

It Will Never Be Easy

Sir Winston Churchill

Never, never, never believe any war will be smooth and easy or that anyone who embarks on that strange voyage can measure the tides and hurricanes he will encounter. The statesman who yields to war fever must realize that once the signal is given, he is no longer the master of policy but the slave of unforeseeable and uncontrollable events… incompetent or arrogant commanders, untrustworthy allies, hostile neutrals, malignant fortune, ugly surprise, awful miscalculations.—Sir Winston Churchill

TV An Ugly Business

The TV business is uglier than most things. It is normally perceived as some kind of cruel and shallow money trench through the heart of the journalism industry, a long plastic hallway where thieves and pimps run free and good men die like dogs, for no good reason.—Hunter S. Thompson

Simplicity, Patience, Compassion

Simplicity, patience, compassion.
These three are your greatest treasures.
Simple in actions and thoughts, you return to the source of being.
Patient with both friends and enemies,
you accord with the way things are.
Compassionate toward yourself,
you reconcile all beings in the world.—Lao Tzu

We Are Here To Unlearn …

Charles Bukowski

For those who believe in God, most of the big questions are answered. But for those of us who can’t readily accept the God formula, the big answers don’t remain stone-written. We adjust to new conditions and discoveries. We are pliable. Love need not be a command nor faith a dictum. I am my own god. We are here to unlearn the teachings of the church, state, and our educational system. We are here to drink beer. We are here to kill war. We are here to laugh at the odds and live our lives so well that Death will tremble to take us.—Charles Bukowski

“An Intellectual? Yes.”

An intellectual? Yes. And never deny it. An intellectual is someone whose mind watches itself. I like this, because I am happy to be both halves, the watcher and the watched. “Can they be brought together?” This is a practical question. We must get down to it. “I despise intelligence” really means: “I cannot bear my doubts.”—Albert Camus
