There is a measure needing courage to adopt and enforce it, which I believe to be of virtue sufficient to redeem the nation in this its darkest hour: one only; I know of no other to which we may rationally trust for relief from impending dangers without and within.

In this quote, Robert Dale Owen speaks about a particular measure that requires great courage to adopt and enforce, which he believes has the power to redeem a nation in its darkest hour. He suggests that this measure, though perhaps difficult or unpopular, holds the virtue necessary to bring relief from the impending dangers that threaten both from outside and within the country. Owen emphasizes that there is no other course of action that offers a rational or viable solution for the nation's survival and recovery.

Owen's words imply that in times of crisis or great peril, sometimes a singular, bold action is required—one that may demand courage and determination to implement, despite the risks. This measure could represent a specific political, social, or economic reform that, though challenging, is crucial for overcoming internal struggles or external threats. Owen stresses that without this action, the nation may not find a way to effectively address its growing problems.

The origin of the quote comes from Owen's involvement in 19th-century politics and social reform. As a prominent social reformer and politician, Owen was deeply engaged in discussions around the country's political and moral issues, particularly during times of conflict and division. His statement reflects the urgency he felt in addressing these challenges and his belief that a decisive and courageous act was necessary to guide the nation through difficult times.

Ultimately, Owen’s quote highlights the idea that in moments of great national crisis, it is often courageous leadership and decisive action that can steer a country toward recovery. His call for a single measure of courage reflects his belief in the power of bold, virtuous decisions to overcome adversity and safeguard a nation’s future, whether through political reform, unity, or other critical actions.
