Each renunciation of instinct feeds conscience, so conscience may paradoxically be called the result of renunciation, which then demands more

Every renunciation then becomes a dynamic fount of conscience; every fresh abandonment of gratification increases its severity and intolerance; and if we could only bring it better into harmony with what we already know about the development of conscience, we should be tempted to make the following paradoxical statement: Conscience is the result of instinctual renunciation, or: Renunciation (externally imposed) gives rise to conscience, which then demands further renunciations.
