An Agnostic Sonnet is a contemporary poetic form that adapts the traditional sonnet structure—typically fourteen lines, often in iambic pentameter, and concluding with a volta or thematic turn—to explore themes of doubt, uncertainty, or spiritual questioning rather than affirming religious or metaphysical certainties; unlike devotional or Petrarchan sonnets that often resolve with faith or revelation, the Agnostic Sonnet embraces ambiguity, skepticism, or existential inquiry, frequently employing irony, open-ended conclusions, or philosophical tension to reflect modern secular or pluralistic worldviews, as seen in works by poets like W.H. Auden or contemporary practitioners who interrogate belief systems without offering definitive answers.
