Why did Franklin rank his virtues in the order that he did?

Franklin ranked his virtues in the order he did because he believed that temperance, silence, order, resolution, frugality, industry, sincerity, justice, moderation, cleanliness, tranquility, chastity, and humility would lead to a well-balanced and virtuous life. He thought that focusing on these virtues in a particular order would gradually lead to improvement in all areas of life.
