"[W]hen people thought the earth was flat, they were wrong. When people 
thought the earth was spherical, they were wrong. But if you think that 
thinking the earth is spherical is just as wrong as thinking the earth 
is flat, then your view is wronger than both of them put together."

14(1), 35-44. Fall 1989.
