Social stability is ensured, not by the cessation of the demand for change – for the needy and the restless will never cease to cry for it – but by the fact that change in its progress must at last hurt some class of men who are strong enough to arrest it. The army of so-called reform, in every stage of its advance, necessarily converts a detachment of its force into opponents. The more rapid the advance the more formidable will the desertion become, till at last a point will be reached where the balance between the forces of conservation and destruction will be redressed, and the political equilibrium be restored.
