" With these vast advantages, ordinary and extraordinary, one would have supposed the North would have been content, and would have at least respected the security and tranquility of such obedient and profitable brethren; but such is not human nature. "
- Robert Toombs

The quote suggests that despite having significant advantages and a clear benefit from their southern counterparts' obedience and stability, the northern entity was not satisfied with this arrangement. The speaker implies that such an outcome would have been expected given the circumstances, but human nature tends to be unpredictable and often fails to act in the predicted manner.

On a deeper level, the quote reflects on the inherent complexities of human behavior and societal structures. It highlights how power dynamics can lead to dissatisfaction even when there is mutual benefit and stability. The phrase "vast advantages" alludes to economic or political leverage that one party might hold over another, while "obedient and profitable brethren" refers to those who are compliant and economically beneficial but still subject to the control of their more powerful counterparts. This situation often leads to tension and conflict as the dominant side seeks even greater control or influence rather than appreciating existing advantages. The quote serves as a reminder that power imbalances can breed discontent regardless of initial positive conditions.

Robert Toombs, the author of this quote, was an American politician and military officer who lived from 1810 to 1885. He served in various roles including as a United States Senator and Confederate Secretary of State during the Civil War era. His insights into power dynamics and human nature are rooted in his experiences with political leadership and the challenges faced by different regions within America, particularly those involving North-South relations leading up to and during the American Civil War.
