A passenger in a taxi leaned o...

A passenger in a taxi leaned over to ask the driver a question and tapped him on the shoulder. The driver screamed, lost control of the cab, nearly hit a bus, drove up over the curb, and stopped just inches from a large plate glass window.

For a few moments everything was silent in the cab, and then the still shaking driver said, "I'm sorry but you scared the daylights out of me."

The frightened passenger apologized to the driver and said he didn't realize a mere tap on the shoulder could frighten him so much.

The driver replied, "No, no, I'm sorry, it's entirely my fault. Today is my first day driving a cab. I've been driving a hearse for the last 25 years."

Jean Piaget

Born 9 Aug 1896; died 17 Sep 1980 at age 84. Swiss psychologist and zoologist. By age 15 he was contributing articles on molluscs to journals of zoology, and his doctoral degree (1918) thesis was on the distribution of molluscs in the Valaisian Alps. Thereafter, he turned to researching how mental growth develops in several successive stages from infancy to adulthood - “the embryology of intelligence” - for which he became distinguished. In the journal Science (27 Jun 1958), he summarized that at the age of eleven or twelve “a child becomes capable of certain formal or abstract operations of thought which before were possible only as concrete operations on properties of the immediately present object world. This provides the last of three mental revolutions during development.”«
