Over at Pharyngula, PZ summarizes a much longer piece with:
It's like asking someone if they understand science, and they can recite a string of facts at you … but they haven't absorbed the concept.
Anyone who's read physicist Richard Feynman's book "Surely You're Joking, Mr. Feynman" knows exactly what PZ is talking about, as Feynman's stint of teaching physics in Brazil is summarized here:
Richard Feynman, in “Surely You’re Joking, Mr. Feynman”, related a story from his experiences teaching science to university students in Brazil. Feynman found that the students in his class could, with great speed and accuracy, recite passages verbatim from their physics text, and give equation upon equation from that text. But when challenged to explain the theories behind what the text postulated, or when challenged to explain the meaning of the equations they were reciting, the students were speechless.
The students believed that they were doing well, because they were in fact getting high marks on their exams (which were really little more than recitation). But the truth was that they had no real understanding of even basic scientific principles. Perhaps even more troubling, they had little or no experience with these principles first-hand. They could certainly recite equations on optics, or gravity, or any other topic in physics, but had they experienced them first-hand? No.
Welcome to most Biblical or Christian "study," in which one is considered a legitimate "scholar" if one can mindlessly regurgitate chapter and verse, with no understanding of their underlying meaning whatsoever. Sadly, most Biblical scholarship doesn't rise much above the level of, oh, this.
