The Form of the Good, or more literally translated "the Idea of the Good" (ἡ τοῦ ἀγαθοῦ ἰδέα^[a]), is a concept in the philosophy of Plato. In Plato's Theory of Forms, in which Forms are defined as perfect, eternal, and changeless concepts existing outside space and time, the Form of the Good is the mysterious highest Form and the source of all the other Forms. It is a Platonic ideal.
