What makes Marley's imperative so resilient is that it collapses the distance between physical and moral action—you cannot merely *think* about justice while seated. The first "get up" isn't decorative; it's the hardest part, the moment you must overcome inertia and comfort to become a person who acts rather than merely wishes. A nurse who documents unsafe staffing practices, knowing it may invite trouble, knows this distinction perfectly: standing up requires the body's commitment, not just the heart's conviction.
