Glimpse Of Heaven

Without questioning the merits or consequences of using one's own children as subjects of scientific experiments, one line in this article made me pause :

Clarence Leuba, a psychologist, wondering if laughter in response to tickling was learned or innate, forbade tickling of his infant son and daughter, except when he tickled them, wearing a mask to hide his expression. (It is innate, he found.)

Even at a few months old, children will respond to funny faces and tickling with gales of uncontrollable laughter. There is possibly nothing nearly as rewarding to an adult as being able to make a baby laugh like that.

It seems that the psychologist and his family made quite a personal sacrifice at the altar of science. Infancy is so incredibly precious because it is so short lived. It would never be possible for them get back to the time when tickling the soles of their infant's feet could instantly reward them with a huge toothless smile - a glimpse of heaven.
