How does author use imagery or figurative language to convey his attitude towards life in "Dover Beach"? Support with evidence from the selection.
The speaker is lamenting the fact that the world is changing. The initial scene is comprised of calm images. The sea is calm, the moon is reflected in the water, and the English cliffs are "glimmering" and powerfully "vast." This visual imagery suggests a world that is marked by peace, beauty, and power. But subsequent lines will describe that world fading into the past. This is/was a world in which faith/religion played a vital role in giving people comfort and a feeling of purpose.
To signify the initiation of the new, scientific era, the speaker shifts from the calm, visual imagery to some shocking auditory imagery:
Listen! you hear the grating roarOf pebbles which the waves draw back, and fling,At their return, up the high strand,Begin, and cease, and then again begin,With tremulous cadence slow, and bringThe eternal note of sadness in.
