Coleridge opens with a radiant, almost ecstatic vision: a single divine Mind, whose essence is Love, pervades everything. To really feed on that truth lifts a soul out of its cramped personal orbit — suddenly you stand in the sun and see all creation with an embracing, blessing gaze. That, for the speaker, is as close to the Almighty as a seraph can fly. But then the mood crashes. The poem looks down on human history and sees a churning “sea of blood,” a family squabbling into violence, every murder a blind suicide. The true majesty of being human, it insists, isn’t rage but recognition: we are “parts and proportions of one wondrous whole,” held together by God diffused through all.
The second section sketches the alternative. Cut off from that sacred centre, a person becomes a lonely, lust-bewitched “smooth savage” roaming through crowds, mistaking his tiny self for the whole world. Yet by sacred sympathy, that same self could stretch outward until it owns and loves everything. That expansive, self-forgetting faith is the poem’s real hope — what it calls the Messiah’s destined victory.
