Final answer:
Personification in Poe's 'The Bells' is used to convey happiness and celebration by giving joyful qualities to the bells, highlighting their connection with life's joyful milestones.
Step-by-step explanation:
Edgar Allan Poe's use of personification in "The Bells" serves to convey the emotional resonance of the bells themselves. When the poem describes the wedding bells as signaling 'a world of happiness' and sharing their delight with the balmy night air, it imbues them with a joyous capability to envision and communicate. The bells are not just sounding; they are actively participating in the celebration of matrimonial bliss, suggesting a harmonious connection between human joy and the natural world's expression of it, as perceived through sound. In this way, the personification underscores the significance and impact of life's milestones marked by the bells' ringing, which symbolize the universal feelings of happiness and celebration associated with marriage.
