Man has a Conscience of what is good, and a Conscience of what is just. The Conscience of what is good is the Conscience of the internal man; and the Conscience of what is just is the Conscience of the external man. The Conscience of what is good consists in acting according to the precepts of faith from internal affection; while the Conscience of what is just consists in acting according to civil and moral laws from external affection. They who have a Conscience of what is good, have also a Conscience of what is just; but they who have only a Conscience of what is just, have the capacity of receiving a Conscience of what is good, and moreover do receive it when they are instructed.
