Free Won’t

Zeno once caught a slave stealing and began to beat him.

Knowing the philosopher’s penchant for paradoxes, the slave cried, “But it was fated that I should steal!”

Zeno said, “And that I should beat you.”

Kaprekar’s Constant

Choose four distinct digits and arrange them into the largest and smallest numbers possible (e.g., 9751 and 1579). Subtract the smaller from the larger to produce a new number (9751 – 1579 = 8172) and repeat the operation.

Within seven iterations you’ll always arrive at 6174.

With three-digit numbers you’ll aways arrive at 495.

Naturally

Someone once asked Jean Cocteau, “Suppose your house were on fire and you could remove only one thing. What would you take?”

Cocteau considered, then said, “I would take the fire.”

Gifted

‘Did you hear the story of the extraordinary precocity of Mrs. Perkins’s baby that died last week?’ asked Mrs. Allgood. ‘It was only three months old, and lying at the point of death, when the grief-stricken mother asked the doctor if nothing could save it. “Absolutely nothing!” said the doctor. Then the infant looked up pitifully into its mother’s face and said—absolutely nothing!’

‘Impossible!’ insisted Mildred. ‘And only three months old!’

Jefferson’s Commandments

A “decalogue of canons for observation in practical life,” sent by Thomas Jefferson to the new father of a baby boy:

  1. Never put off till tomorrow what you can do to-day.
  2. Never trouble another for what you can do yourself.
  3. Never spend your money before you have it.
  4. Never buy what you do not want, because it is cheap; it will be dear to you.
  5. Pride costs us more than hunger, thirst and cold.
  6. We never repent of having eaten too little.
  7. Nothing is troublesome that we do willingly.
  8. How much pain have cost us the evils which have never happened.
  9. Take things always by their smooth handle.
  10. When angry, count ten, before you speak; if very angry, an hundred.

It’s not clear what a smooth handle is. Possibly it refers to a saying by Epictetus: “Everything has two handles, one by which it can be borne, another by which it cannot.” Or possibly Jefferson was referring to the need for civil discourse.
