of being wise and isolation...

I thought I post this excerpt from an interview with J.K. Rowling with The Leaky Cauldron and Mugglenet on the day the 6th book was released; it contains a very interesting and insightful take on Dumbledore's attitude - which I personally agreed with.

ES: I know Dumbledore likes to see the good in people but he seems trusting almost to the point of recklessness sometimes.

[Laughter] Yes, I would agree. I would agree.

ES: How can someone so -

JKR: Intelligent -

ES: be so blind with regard to certain things?

JKR: Well, there is information on that to come, in seven. But I would say that I think it has been demonstrated, particularly in books five and six that immense brainpower does not protect you from emotional mistakes and I think Dumbledore really exemplifies that. In fact, I would tend to think that being very, very intelligent might create some problems and it has done for Dumbledore, because his wisdom has isolated him, and I think you can see that in the books, because where is his equal, where is his confidante, where is his partner? He has none of those things. He’s always the one who gives, he’s always the one who has the insight and has the knowledge. So I think that, while I ask the reader to accept that McGonagall is a very worthy second in command, she is not an equal. You have a slightly circuitous answer, but I can't get much closer than that.

ES: No, that was a good answer.

MA: It's interesting about Dumbledore being lonely.

JKR: I see him as isolated, and a few people have said to me rightly I think, that he is detached. My sister said to me in a moment of frustration, it was when Hagrid was shut up in his house after Rita Skeeter had published that he was a half-breed, and my sister said to me, “Why didn't Dumbledore go down earlier, why didn't Dumbledore go down earlier?” I said he really had to let Hagrid stew for a while and see if he was going to come out of this on his own because if he had come out on his own he really would have been better. "Well he's too detached, he's too cold, it's like you,” she said!" [Laughter] By which she meant that where she would immediately rush in and I would maybe stand back a little bit and say, “Let's wait and see if he can work this out.” I wouldn't leave him a week. I'd leave him maybe an afternoon. But she would chase him into the hut.
