Idea of the Good
Hegel (theory of the Idea, practical Idea)
The Idea of the Good is the practical Idea --- the will that seeks to realize the true. Distinction from the theoretical Idea (Idea of the True): the theoretical Idea seeks to know the world (accepts it as given), the practical Idea seeks to change the world (makes it good). The Good is not merely subjective intention but objective purpose. Problem of the practical Idea: it stands opposed to the world (ought vs. is) --- the world is not yet good. Resolution: in the absolute Idea, the opposition between theory and practice is sublated. This does not mean that everything is good (a legitimation of what exists), but rather: the Good shows itself in historical practice --- where "shows itself" does not mean legitimation but proving itself against experience (see Chapter 23a on the distinction between comprehending and justifying).
Origin
Plato: idea tou agathou (Idea of the Good, the highest Idea). Aristotle: to agathon (the good as telos). Kant: the categorical imperative. Hegel: the Good as the practical Idea that realizes itself in history.
