The second epistle abruptly turns to focus on the principles that guide human action. The rest of this section focuses largely on “self-love,” an eighteenth-century term for self-maintenance and fulfillment. It was common during Pope’s lifetime to view the passions as the force determining human action. Typically instinctual, the immediate object of the passions was seen as pleasure. According to Pope’s philosophy, each man has a “ruling passion” that subordinates the others. In contrast with the accepted eighteenth-century views of the passions, Pope’s doctrine of the “ruling passion” is quite original. It seems clear that with this idea, Pope tries to explain why certain individual behave in distinct ways, seemingly governed by a particular desire. He does not, however, make this explicit in the poem.
