"The devil's name is dullness"

This quote by Robert E. Lee talks with the idea that a lack of enthusiasm and also imagination can be a harmful thing. Monotony can be seen as a type of complacency, where one is material to remain in their comfort area and also not pursue even more. This can result in stagnancy as well as a lack of progression. Dullness can also be viewed as a form of passiveness, where one is not inspired to do something about it or make a distinction. This can lead to a lack of aspiration and an absence of objective. In this feeling, monotony can be seen as a type of evil, as it can result in a lack of progression and also a lack of gratification. By calling dullness the evil one's name, Lee is alerting us of the threats of complacency as well as lethargy, as well as motivating us to strive for even more.
