In my opinion ,I think each person has many forms, there are both good people and bad people .We do not know that doing good . Someone thinks good that another people may think different. Because we do not have a fixed format in each time. If there is a perfect model , it will be just alone .Plato says that everything is perfect, but we are not perfect. If integrity of a world that Plato said there live. Because everything perfect And perfect just the way it should be. We can not deny that his theory is right or wrong. Because it is the only theory that knowing or catching . Why Plato realized that everyone was incomplete. In this time ,who know right theory? I think ,nobody knows that real or worng. The scientists can not prove this theoty. According to the principles of truth, then no one would be the perfect man. No matter the shape, appearance, or any other ideas. Sometime I think about perfect form when I consider what I want. The integrity of the individual are not the same. It depends on the satisfaction of each person.
