Parsimony Principle (IV): Skepticism


It goes without saying that the world needs more gullible.
radical philosophical skepticism is contradictory, because the statement "we must doubt everything" contradicts the truth claim that he proposes.

not easy to prove things. If we confine ourselves to operate with that which is highly evident, we would cease to have much of our therapeutic arsenal. The more information and knowledge you have, the easier it is to identify the grain in the straw.

Common sense, logic and the principle of parsimony should be used also in disbelief. If it looks like shit and smells like shit ... taste it is unnecessary to confirm.



I leave you with a story of German children's writer, Peter Bichsel.


just see what I

"I met a man who only believed in what he could see and experience personally. Learned in school that the Earth was round and everyone repeated. But he said: "I'll believe it only if I can make the experience: I leave my house by the front door, go straight on and once I get done all the way to the back door. Only then is found in fact that the Earth is round.

wanted to implement its purpose immediately. She bought clothes for different seasons, winter clothing, shoes and boots. He said: "I need a car to get it inside." Vio also across the street was a house. To pass over the house would need a ladder. He recalled that there was a river below. Need a boat to cross. To transport the boat needed another larger car. And someone to drive it. This person would also need clothes and other belongings.

later recalled that there was a lush mountain forest. How do the two cars up the ladder and the boat up the mountain? Need at least five men. For those men need at least two other cars, because everyone would have to carry their belongings. And to pass it all over the house would require a crane. And a truck to transport the crane. And a man who handled the lift. It would also have to carry things. And even greater need another ship to carry the crane. And more still ... trolley

Here she stopped. He took a sheet of paper and made the first calculations, needed supplies for eight people, including himself, four cars, a truck, two boats, a crane and a ladder. Should not forget the salary of those hired. It was agreed that later would face the ocean and should to have a ship to load everything and make the crossing. Did the math and saw that it would require a large fortune.

Upon realizing the mess he had gotten was very sad. More sorry was when he realized he was already 65. He had to hurry if he wanted to return before his death.
But not deterred. Do not buy anything from that long list. Only a big step. It threw her over his shoulder and slowly walked to the house opposite. Put a ladder and started climbing slowly.
People who knew what they wanted from the street shouted: 'Man, leave it. No need to prove that the Earth is round. Everyone knows'. But he was deaf. He climbed to the top of the roof and raising the ladder it disappeared on the other side.

never returned to see the man. Maybe he changed his mind, he may have died already, but occasionally I like to go to the window and look westward. How happy would be if I saw one day come to me saying, 'Now I know from experience: the Earth is round'. "
