"Jane Cleaver is the same. She has an eighth-grade education."[emphasis added]
I assume she's one of the defendants; i.e., a member of the Dover School Board.
Who in their right mind would rely on a person with an eigth grade education to determine what is and is not a valid scientific theory, or worse still, what the definition of science ought to be? Her scientific knowledge clearly isn't the basis for her decision regarding the ID statement, so what then is it that informs her that she and her fellow Dover School board members should go tampering with the definition of science so as to include supernatural causation? Perhaps her own beliefs in the "supernatural"?
While not commenting on this particular person, one should not confuse the level of formal education with real learning and understanding. After all, Bill Gates is a college drop out. He didn't make it past his first year of college.
Sure, he is an extreme example; but it does make a valid point. Lincoln was not a formally trained lawyer, but was nevertheless and very successful one.
