Good through the idea of One allows scholars to explain how Plato's Form of the Good relates to the physical world. According to this philosophy, in order for an object to belong to the Form of the Good, it must be One and have the proper harmony, uniformity, and order to be in its proper form. Philosopher Rafael Ferber dismissed Aristotle's view that the 'Good' is 'One' and wrote that the Form of the Good is self-contradictory. Ferber claimed that Plato's Form of the Good could be simultaneously defined and unknown, and be in a state of both "being" and "not being". Plato's Forms are also critiqued for being treated as the reason for all things, as opposed to being an essence in itself. Some scholars also believe that Plato intended the Form to be the essence of which things come into existence. These different interpretations of Plato's intention for the Form may be attributed to the idea that Plato did not have a systematic definition of the Form itself. Influence Plato's writings on the meaning of virtue and justice permeate through the Western philosophical tradition. Plotinus, the founder of neoplatonism, had principles that were heavily influenced by the Good. His concept of 'the One' is equivalent to 'the Good' because it describes an ultimate ontological truth. 'The One' is both 'uncaused' and the cause of being for everything else in the universe. Plotinus compared his principle of 'the One' to an illuminating light, as Plato did with the Form of the Good. As a result of Plotinus' school of neoplatonism, the bulk of understanding of Platonic philosophy until the 19th Century came through Plotinus' interpretation of it. Many theologians and philosophers of Judaism, Christianity and Islam looked to the ideas of Platonism through the lens of Plotinus. Amphis, a comic playwright of Athens, has one of his characters say: "And as for the good that you are likely to get on her account, I know no more about it, master, than I do of the good of Plato." There is an ancient anecdotal tradition that Plato gave a public lecture entitled "On the Good" which so confused the audience that most walked out. At the end of the lecture Plato said to those hearers who remained: 'The Good is the One".
