REP. HENRY WAXMAN: Do you feel that your ideology pushed you to make decisions that you wish you had not made?
ALAN GREENSPAN: Well, remember that what an ideology is, is a conceptual framework with the way people deal with reality. Everyone has one. You have to — to exist, you need an ideology. The question is whether it is accurate or not.
And what I’m saying to you is, yes, I found a flaw. I don’t know how significant or permanent it is, but I’ve been very distressed by that fact.
REP. HENRY WAXMAN: You found a flaw in the reality…
ALAN GREENSPAN: Flaw in the model that I perceived is the critical functioning structure that defines how the world works, so to speak.
REP. HENRY WAXMAN: In other words, you found that your view of the world, your ideology, was not right, it was not working?
ALAN GREENSPAN: That is — precisely. No, that’s precisely the reason I was shocked, because I had been going for 40 years or more with very considerable evidence that it was working exceptionally well.
