In this excerpt from Walden by Henry David Thoreau which element of style does the author use to illustrate a comparison?

In "Walden," Thoreau employs imagery and metaphor to draw comparisons that enhance his philosophical reflections on nature and society. For instance, he often likens the simplicity of rural life to a more profound understanding of existence, contrasting it with the complexities of modern civilization. This stylistic choice not only paints vivid pictures in the reader's mind but also invites deeper contemplation of the themes he explores. Through these comparisons, Thoreau effectively communicates his advocacy for a more intentional and harmonious way of living.
