“The death of a newborn child before that of its parents may seem an unnatural, but it is strictly a probable, event,” observed Edward Gibbon in his Memoirs. He was his parents’ first child; the next six all died in infancy. Some twenty years earlier, Jean-Jacques Rousseau wrote, “One half of the children who are born die before their eighth year…This is nature’s law; why contradict it?”

After watching a performance of his play Peter Pan with his five-year-old godson, J. M. Barrie asked the boy what he had liked best. “What I think I liked best,” the boy replied, “was tearing up the program and dropping the bits on people’s heads.”

Thomas Edison received three months of formal education at the age of eight before his mother homeschooled him. Benjamin Franklin quit school at age ten, Charles Dickens at twelve.

“I went sailing up to Great Point, which is fourteen miles. It was fine and rough so we went out in the open ocean and shipped water grandly.

The poet did not start using Rainer instead of René until he was in his twenties.
