I personally believe in the mutability premise over the rationality and perfectibility premises. In regards to the rationality premise, I don’t believe that most people are able to logically discover truth. There are many people in our society who are very good liars. No matter how much logic a person uses, there are times when they can be totally oblivious to the truth. An institution that relies on this logic is the U.S. court system. We rely on trial by jury because many people believe that most people would be able to find truth buy using logic. Unfortunately, many guilty people are set free to roam the streets because their lawyers do a great job avoiding the truth. As for the perfectibility premise, I don’t believe that everyone is born a sinner. I think that the ancient Christian and Catholic churches like to push this idea so that their society would maintain some sort of order. People wanted to do good, because if they weren’t good then they would go to Hell. This sort of logic scared people and made them less likely to commit crimes. On the other hand, the mutability premise seems much more logical to me. I really do believe that people are shaped by society and that the circumstances that they may encounter within their lifetime have a huge effect on the way the person develops. I think that many institutions that provide help for orphans, refugees, rape victims, and homeless people tend to support this sort of idea.
