President George W. Bush favors teaching both evolution and "intelligent design" in schools, "so people can know what the debate is about."
To proponents, intelligent design is the notion that the universe is too complex to have developed without a nudge from a higher power than evolution or natural selection.
To detractors, intelligent design is creationism -- the literal interpretation of the Book of Genesis -- in a thin guise, or simply vacuous, about as interesting as "I don't understand" as has always been true in the sciences before understanding is reached.
Accordingly, there cannot be a "debate."
The teaching of evolution has long been difficult in the United States. Now, a national movement has emerged to promote the teaching of intelligent design in schools.
The issue has famously surfaced in a courtroom in Dover, Pa., where a school board is requiring students to hear a statement about intelligent design in a biology class -- and parents mindful of the U.S. Constitution's church/state separation have sued the board.
