The origin and nature of the evil of the Plato world about the existence of a negative form has plagued philosophers. Ancient philosopher Plato did not solve this problem directly in his work, but the logic of his formal theory needs a formal negative sense like evil and evil I will. In discussing his imitation theory of imitation, Plato implied the principle that when there are many of the same nature there is a form that exists.
In the Republic of Plato, his formal theory thinks the world we are experiencing is merely a representation of the real world - this is the shape world. Due to the existence of each tree there is a world in the form of "real" shapes of trees. All of our incredible world trees are just trying to duplicate trees, but we can not reproduce the real tree perfectly. He believes that all perceptible things exist in this field. This field is probably just a figurative field trying to explain the subjectivity of justice, kindness, beauty, but there are still many scholars interpreting Plato literally as we can explain Plato
Plato's strange proposal is difficult to understand. He said there is an "understandable field" with forms of justice, kindness, beauty that can only be thought of as an idea. According to Plato, the performance of these on earth is only a minor reflection of the perfect form in the world that you can understand. He believes that the purpose of philosophers is to understand and understand these forms. But Plato's form is not just a moral concept. He also pointed out that geometric students "use visible shapes and demonstrate them without considering them" (Republic, p. 206). For example, you can draw a square with a diagonal and you can argue that its diagonal divides the square into halves, but you do not really talk about what you are painting, you know the concept of a square and a diagonal We are talking about - or as Plato said, their shape
Aristotle's shape is very different from Plato's shape. If Plato is seeing the shape as an independent presence, Aristotle is also so. Essentially, for Aristotle, the form is the organizational principle of matter. There is no form of things at all. In this way, the word "form" coincides with modern usage like "form", but the soul is not merely a form. Aristotle distinguishes different kinds of souls. Plants only have a soul of nutrition (ie they are organized in nutrition, growth and decline). Animals have sensuous / perceptive souls (ie, animals are organized to have nutritional souls, but they also have the ability to perceive and perceive things). People have a reasonable soul (ie, they are organized to have all of the above, there are even more reasons)
