Franz' book is Crisis of Conscience, if I recall correctly. One of the people mentioned in the book (actually the recipient of a letter that is reproduced in it) is a fellow I have known for almost all of my life. I got a chuckle out of seeing it, but was not surprised.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
