Write the themes of the poem"the second coming" in detail.
"The Second Coming" by Yeats presents a second coming of a different kind; different from the second coming Christian tradition presents.
The poem presents social upheaval and nightmarish violence. The falcon cannot hear the falcon, and thus cannot be controlled: chaos results. Those who could do something about the discord "lack conviction," while the worst are filled with "passionate intensity." An ambiguous, sphinx-like creature with a "gaze blank and pitiless as the sun,/Is moving its slow thighs" toward Bethlehem (metaphorically) to be born. The "rough beast" is coming. Nightmarish violence is coming: not the second coming of Christ that tradition expects.
Human history is about to take a turn for the worse.
Yeats is responding to upheaval and violence in the world, and particularly in the Russian revolution. The 20th century is on the verge of something terrible, the poem suggests. And of course, Yeats was correct. Human beings were never so good at killing other human beings as they were in the 20th-century.
In order to discuss the important themes in the poem "The Second Coming" by Irish Poet William Butler Yeats, you will need to conduct some research in several areas, doing some background reading. Start with Yeats' biography - there you will see background to do with the history of Ireland, his early lyrical poetry, his later more cynical modernist poetry and his religious influences. Then look at the idea of Nativity - particularly with reference to Christianity in the Bible and the idea of the arrival and later further revelations of the Messiah. Look also at the bloody struggle for Irish independence and the portents for war in the whole world at the time. That should be more than enough detail!
