For the most part I don’t believe in the rationality and perfectibility premises. The reason why I don’t agree with the rationality premise is that I really don’t believe that most people are rational. Let’s take religion for example. When you are a religious fanatic your mind can’t be changed. Even when someone brings a rational argument they won’t budge from their beliefs, so no I don’t agree with the rational premise. I really don’t believe that we are born as sinners. When a baby is born what possibly can a baby do that could be considered bad. I’m not a big fan of the words good and bad. I believe that we chose to either be good or bad. We as humans have something that most being don’t have. We have free will. But I believe in the mutability premise. We are indeed shaped by our environment and that we could improve our physical and psychological circumstances. The first two I don’t believe, but for the mutuality I believe in. For the rationality premise I belive that most Americans believe in this. For the perfectibility premise I believe that christens believe in this. For the mutability premise, maybe Buddhism.
