Dave, are you talking about Terry when you say there is an “unanswered question as to why such an eminently experienced, intelligent educator got the impression that we didn’t care about education. I don’t know.”? I don’t see in his post (http://terrya.edublogs.org/?p=632&preview=true) that he believes you “don’t care” about education.
What he’s pointing at is more that the personal intention is what defines anything’s real worth (cp. Dalai Lama’s comments on euthanasia), i.e., this rhizomatic learning can/will also be distorted by human ambition, etc. and so there is no panacea.
