Aristotle managed to be a devoted student even though he disagreed with Plato on his theories. Plato the teacher believed in Forms which he thought where prior to the physical world, and that Forms are eternal, unchanging and indivisible. Aristotle believed that the physical world was prior to the Universals and the particular things in the physical world are called, "thises," things that have substance. The Universals are called, "suches," they are modifications of things that have properties.
In general, we can say that Plato's philosophy is depicted in Allegory of the Cave. The allegory of the liberation of the slave from darkness, deceit, and untruth and the slave's hard journey into the light and warmth of the truth has inspired many philosophers and social leaders. (Palmer, p.59) in the allegory of the cave: .
Sensible Realm vs. Realm of Forms.
The Cave Outside of Cave.
Source of error Source of true knowledge and all reality.
Ignorance Exists in dependently of our minds .
Senses deceive (changing) (being, unchanging/eternal).
This is Plato's two-layer view of reality. For Plato it is the difference between appearance and reality, though he expressed it also by means of the terms Becoming and Being. There are six features of Forms which are Objective: they exist "out there" as objects, independently of our minds or wills. Transcendent: though they exist "out .
there," they do not exist in space and time; they lie, as it were, above or beyond space and time. Eternal: as transcendent realities they are not subject to time and therefore not subject to motion or change. Intelligible: as transcendent realities they cannot be grasped by our senses but only by the intellect.
