I wonder why the downvotes, it's actually a quite thought provoking question.

No it's not, it's an insult.

Disagree! It's a brilliant comment. Should really be at the top, in my view :) - though as food more for thought than discussion.

I will try to explain, though I think it's obvious - at least, once you've read that comment (which is why I like it so much - maybe to others it was obvious beforehand, in which case I apologise for being dense).

Here is an article about this guy discarding beliefs that he's held for a long time. These are beliefs that I suppose you might call his doctrine, in that he held them without really questioning them. Well: great! Unquestioned beliefs, questioned and revisited, changed in the face of the evidence, or whatever. And he seems happy with the result.

How many similar beliefs might he hold in total?

If changing one set of beliefs for another is worth doing, what about some other set?

Would it be worth his adopting this as more active process, rather than simply waiting for events to demonstrate that some arbitrary set of beliefs are worth changing?

Is there a wider lesson here?

(Etc., etc.)

That's exactly how I interpreted the 'insulting' comment. We tend to compatimentalize ourselves at a rational level, but sometimes fail to see the 'bigger picture' of our mental patterns and the impact they have.

My thought too.

When I read the comment, I thought, "perhaps reevaluating long held beliefs leads to some new creativity or insight."
