Over the many years of humanity, there have been many "facts" that have been later proven to be false. There was a time when the earth was believed to be the center of the solar system. Today we know that this is not the case. The point is, if all you do is spit out facts at people, like in the excerpt from Charles Dickens' novel, you rob them the chance to form their own opinions. A progressive style of teaching allows students to decipher the information in their own manner. They have the opportunity to accept or disagree with information regardless of how the teacher giving the lesson may feel. If we are forced to always accept one answer to our questions, we don't have the option to consider multiple angles. People need to learn to question the way things have always been done, not to cause chaos or use it as a form of spite, but simply to be able to understand how they really feel about things. If all your faith is put into a belief that you don't truly agree with because of what other people say, that belief will not make any sense when you're all alone forced to truly consider it.
