In lecture six, we explore the profound impact of World War I on Western intellectual thought through the poetry of W. B. Yeats and T. S. Eliot, examining how both poets grappled with the collapse of traditional values and the search for meaning in a fractured civilization. We analyze Yeats's cyclical view of history in "The Second Coming" and his quest for spiritual permanence in "Sailing to Byzantium," alongside Eliot's fragmented vision in "The Waste Land," which depicts a spiritually barren modern world. The lecture concludes by highlighting how both poets, despite their different approaches, ultimately argue that life requires connection to something eternal or larger than oneself to have meaning.
