On the War Tour and leading up to recording "The Unforgettable Fire", U2 lead singer and lyricist, Bono, had become a voracious reader. He read fiction, philosophy and poetry, and came to realise that his song-writing mission—which up to that point had been a reluctant one on his behalf—was a poetic one. He read works of poet Paul Celan, whose line "poetry is a sort of homecoming" inspired not just the song's title but the song itself. Celan's profound spiritual doubt contrasts with U2 members' previous religious certainties. The song's line "on borderlands we run...and don't look back" suggests the band had become more comfortable with the contradictions between rock and religious beliefs in comparison to during the "October"-"War" period. The phrase, "poetry is a sort of homecoming" had additional significance for Bono as a singer who was constantly away from home and travelling.
