No one needs to be told how to think because we are all born with that capacity. Yet we know some persons are insane, others very troubled. There are people who are career criminals, and we all make mistakes. Lots of people ruin their lives by the number of bad choices they make. Every day people die from drugs and more begin taking them knowing the path they are on. We also know some people are geniuses, some are creative and others well organized. So, then the question becomes, do those who believe we all know how to reason, know how to evaluate the data they are faced with? If you think everyone knows you to reason, perhaps you do not know how to reason correctly. How would you know?
