“Once More to the Lake” by E.B. White Essay

These linked ideas blur the line between birth and death, and serve to establish the truth that the cycle from creation and mortality is universal.At first, while his illusion from the similar shape of the outdoors gives the false perception that time has not past, his pinpointing of the different identities of the son and father serves as testimony that the cycle from birth to death is universal.Here, White’s language has bulls-eye precision, and the dragon fly is transformed into a representation of the continuous cycle of life and death.The sea has the remnant memories of “restlessness of the tides and the fearful cold of the sea water and the incessant wind.” The sea symbolizes the harshness of aging, while the lake symbolizes the fa...
