Shakespeare at 400, Jack London at 100: Genius Lives, by Jonah Raskin

   In William Shakespeare’s comedy, “As You Like It, a traveler named Jaques waxes poetical in lines that have achieved literary immortality.

   “All the world’s a stage,” he says. “And all the men and women merely players;/ They have their exits and their entrances,/And one man in his time plays many parts.”

   Three hundred years later, Jack London, another melancholy traveler, might well have spoken nearly the same lines and meant them to be about himself.
