Dover Beach by Matthew Arnold
Arnold mentions how such sorrows have long engulfed our world. The poem of course was written about the Dover Beach what sets it apart from any other picturesque admiration of a place is that he talks of how in a world as beautiful as this faith and hope has left men. He found it hard to succumb to the thought that science could provide any parallel to religion and feared the absolute loss of belief in God. The poem therefore talks of a light on the French coast which comes for a fleeting moment and is gone. The “light” that Arnold writes of represents the idea of Faith in people.
Arnold begins the poem by describing an enchanting view of the white cliffs of Dover: the cliffs gleam, the night air brings sweet scents, and the bay below is tranquil with the exception of the foamy white breakers that send up plumes of spray. The poet describes the beauty of the beach situated in the town of Dover. It is closer to France than any other port city in England. The “straits” that has been mentioned is the Strait of Dover, north of the English Channel and south of the North Sea. Each expression that talks of the place tends to describe not just the place in itself but also points indirectly at the state of the world. Perhaps Arnold saw in the sea meeting the “moon-blanched” land, the idea of beauty so terribly real that it hurts the heart. And in the “great roar” he heard the endless attacks on the church by the scientists of the time. That could be why the beautiful rhythm of the water beating through the rocks brought “the eternal note of sadness”. This scene, while lovely, does not bring the observer joy. Instead, Arnold writes, “Listen! you hear the grating roar / Of 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 bring / The eternal note of sadness in.” The poet draws a parallel between the pebbles trapped in the tide’s cycle of ebb and flow and the similarly cyclical forces that have throughout history brought suffering to humankind.
The second stanza connects Arnold’s sense of sadness in the sea to the ancient Greek playwright Sophocles’ tragic sensibility. “Sophocles long ago / Heard it on the Aegean, and it brought / Into his mind the turbid ebb and flow / Of human misery; we / Find also in the sound a thought, / Hearing it by this distant northern sea.” By attributing his own interpretation of the sound of the sea as a metaphor for the relentless nature of human sadness to the ancient Sophocles, Arnold expresses that this sadness, like the tides, is both timeless and inevitable.
His despair has no ending as he then talks of “The Sea of Faith” which used to wrap around us like an ocean wraps around continents. That sea has now withdrawn leaving the “naked shingles”. Science has challenged the precepts of theology and religion; human misery makes people feel abandoned, lonely. For the loss of Faith has left them with nothing but despair. While the second stanza described the tide of human sadness as eternal, this third stanza implies that this sadness has recently been worsened by the degeneration of faith, either to a higher power or toward one another.
He implores his beloved wife to be true to him. While these lines can be considered as being addressed to his wife, they can also be taken as general message to all people in the world. He explains how in a world which falsely claims to be a land of dreams but in actual fact has “really neither joy, nor love, nor light, nor certitude, nor peace, nor help for pain” , we all have a duty if not a right to at least be true to our loved ones. While science is what challenged the faith then, it is war that challenges our faith in each other now. Dover Beach is indeed a poem beyond its times for the mere fact that the world still lies on the brink of darkness and the only way it can be saved is by Faith, if not faith in God then at least by faith in our own hearts.
The poet claims that the dazzling beauties of the natural world contain no true joy for humanity. Instead, we make our way through the world like soldiers caught up in a night battle, frightened, confused, knowing neither why we fight nor whom we struggle against. Only by remaining true in love, and perhaps thereby restoring to some extent the Sea of Faith, can we anchor ourselves to something good in the world of confusion and misery.
Dover Beach is Arnold’s message to the world to save itself from its own sea of sorrows. What interested me in the piece of literature is that while the world seemed to be plagued then with lack of Faith, it still seems to be wilting due to the same problems. And that for me is a positive sign for if the world managed to survi
