Socrates never wrote any of his In the Realm of Forms exists a true or perfect form of everything. EG. A the truth work down. Plato, however, wrote a series of dialogues, the most famous form of beauty. A FORM is unchanging. It is not a physical thing, but a of which is called The Republic. The dialogues put across philosophical CONCEPT or idea. It is the eternal idea of what a thing is. Our soul Analogy Understanding ideas through conversation.

The jump to a real life situation isn’t really there. Ancient Greek Philosophy: Aristotle Aristotle was an empiricist. He thought the way to deepen his Aristotle saw that the world around him was in a state of constant motion. Characteristics of the Prime Mover: understanding was through experience. He thought the only knowledge To Aristotle motion means change. He was able to experience this we could have is of the empirical world (that which we can experience change with his senses, making the evidence of change EMPIRICAL. Necessary: God is something which has always existed and always had though our senses). Therefore, his statement that the world was in constant change was A to exist. God does not depend on anything or anyone to exist. POSTERIORI. Aristotle disagreed with Plato about his idea of Forms. He did not believe Eternal: God has no potential. God cannot change. If God cannot change there was a separate ‘ideal’ realm. He believed that a ‘form’ was Things change because they exist in an ‘actual’ state and have the then God cannot stop existing. If God cannot stop existing God must distinctive to each object. Key question for Aristotle: Why are things the ‘potential’ to become another. These states are known as ‘actuality’ and always have existed. way they are? He realised there were different ways to answer this ‘potentiality’. The state something is in and the state it can change into. Perfectly good: Badness corresponds to a lack of something. God is pure question…this lead to his Theory of the Four Causes. actuality, so contains everything. Therefore, God must be perfect. What caused this desk to be the way it is? Immaterial: All physical matter has the potential to change. God cannot change, therefore is immaterial. God is immaterial so cannot perform any physical activity (remember God can be the final cause without physical activity. Consequently, God is spiritual and pure thought. God cannot think of anything that could cause a change therefore God must only think of his own pure state or perfection. Actuality- Cow Potentiality- Beef Burger Evaluation 1. Material cause.
