The intelligent design vs. Darwinism debate presumes that one or the other theory provides the answer to life and all its mysteries. Playwright Seth Greenland explores the falsity of this dichotomy in "Jerusalem," his play opening Friday at the NoHo Arts Center. Greenland's five principal characters -- a Jewish psychiatrist, his Protestant wife and his in-laws -- have varying degrees of religious faith, as well as varying degrees of conviction about psychoanalysis. In the end, Greenland seems to say, the wise man understands the merits of both religion and science. Even the wise man, though, knows the limits of his knowledge.
