Reminds me of a lecture given on Beginner's Mind that emphasizes the pitfalls of intellectualism:
'Can we look at our lives in such a way? Can we look at all of the aspects of our lives with this mind, just open to see what there is to see? I don't know about you, but I have a hard time doing that. I have a lot of habits of mind—I think most of us do. Children begin to lose that innocent quality after a while, and soon they want to be "the one who knows." We all want to be the one who knows. But if we decide we "know" something, we are not open to other possibilities anymore. And that's a shame. We lose something very vital in our life when it's more important to us to be "one who knows" than it is to be awake to what's happening. We get disappointed because we expect one thing, and it doesn't happen quite like that. Or we think something ought to be like this, and it turns out different. Instead of saying, "Oh, isn't that interesting," we say, "Yuck, not what I thought it would be." Pity. The very nature of beginner's mind is not knowing in a certain way, not being an expert. As Suzuki Roshi said in the prologue to Zen Mind Beginner's Mind, "In the beginner's mind there are many possibilities, in the expert's there are few." As an expert, you've already got it figured out, so you don't need to pay attention to what's happening. Pity.'
"Not necessarily a pity. You have to be an expert at some things in order to become a beginner at others."
True, but I don't think that's the point of the passage. Rather, the idea is not to seal one's mind off at the "expert" level in any field of endeavor. At that point, we replace questions with assumptions. Those assumptions might be based on knowledge, and they might be right (for now). But who's to say that they're going to be right tomorrow? Or the next day? Or that a better way won't emerge? (It definitely will not emerge from the one who assumes he's mastered it, because he won't question what he assumes he's mastered).
