Biology-Watcher or Participant?

To the Editor: In his most recent article (N Engl J Med 290:388, 1974) Dr. Thomas suggests that the present intensification of communication, transportation and multi-media may constitute the elements of a new primal ooze, which may produce an exciting evolutionary novelty. What we are now, according to Dr. Thomas, is the result of some impersonal event (or events) plus time and chance, and what the human race becomes will be the result of more of the same. But in describing so well some of the logical conclusions of Naturalism, he is naïvely insensitive to some of the tensions inherent. . .
