This episode begin with Socrates' astounding claim that "only philosophers should be kings." However, he soon qualifies this with the remark that he does not mean philosopher in name only. He means philosophers who have a specific kind of knowledge that he calls "knowledge of the form Good." The remainder of this episode is a journey through the distinction between forms (concepts) and the particular things that participate in the forms, including forms that participate in other forms. What is the difference between beautiful things (works of art, music, sculpture) and the form Beauty itself? How does the form Beauty participate in the form Good?
