From too much liberty my Lucio, liberty: As surfeit is the father of much fast, So every scope by the immoderate use Turns to restraint.
Too much freedom, my Lucio, too much freedom: Just like overeating leads to fasting, So does too much freedom eventually lead to restraint.
Claudio · Act 1, Scene 2
Claudio, imprisoned for consummating his betrothal before marriage, diagnoses the play's central paradox in his first scene. The line is remembered because it frames the entire conflict—that excessive freedom invites excessive law, and both are forms of imprisonment. It tells us that Claudio understands himself better than Angelo understands himself, and that the play is about the balance between desire and order.
