Glass clarifies that idea:
…the intellectual and moral journey we want to make toward wisdom and virtue requires a similar recognition, and that is this: I do not have wisdom. I want to know, but I do not yet know. There is still something to be learned. That realization requires humility, which does not seem to come naturally to human beings … (pg 25-26, italics hers)
and, “If we are humble, we are teachable.” (pg 26).
Pride in our intellectual achievements, hubris, is a death knell to the kind of real education that produces virtue, and children are very susceptible to being drawn into this kind of pride, as are their parents. (pg 26).
Finally, the passage that really reminded me of Mr. Darcy:
If virtue is the true goal of classical education, pride in intellectual achievement is the perfect stumbling block to ensure that the goal is never reached. In other words, we must not only become humble, but remain humble if we want to continue our pursuit of wisdom and virtue. (pg 26, italics hers but would have been mine if not included)
