I thought the discipline section was interesting, as well as the questioning section. The cyclical nature of critical thinking requires all the elements work in order to reach articulate, viable solutions to problems. Questioning is certainly something that needs to be encouraged more in education. Without it, we can't learn from our mistakes or dissapate confusion and misunderstanding. The discipline section was a breath of fresh air, given how instant-gratification-based our society is. I'm glad to know folks are still trying to incorporate it to develop strong critical thinkers.
