Socrates told us, "the unexamined life is not worth living." I think he's calling for curiosity, more than knowledge. In every human society at all times and at all levels, the curious are at the leading edge.

Why is it that English, drama and music teachers are most often recalled as our mentors and inspirations? Maybe because artists are rarely members of the popular crowd.

What we have here is a rousing boy's adventure story, adapted from stories that Edgar Rice Burroughs cranked out for early pulp magazines.

Dr. Leonard Shlain, chairman of laparoscopic surgery at California Pacific Medical Center, said they took some four and five year-olds and gave them video games and asked them to figure out how to play them without instructions. Then they watched their brain activity with real-time monitors. At first, when they were figuring out the games, he said, the whole brain lit up. But by the time they knew how to play the games, the brain went dark, except for one little point.
