Contrasting or combining two terms, phrases, or clauses with opposite meanings. William Blake pits love’s competing impulses—selflessness and self-interest—against each other in his poem “The Clod and the Pebble.” Love “builds a Heaven in Hell’s despair,” or, antithetically, it “builds a Hell in Heaven’s despite.” [fieldset=The Clod and the Pebble by William Blake]"Love seeketh not itself to please, Nor for itself hath any care, But for another gives its ease, And builds a Heaven in Hell's despair." So sung a little Clod of Clay Trodden with the cattle's feet, But a Pebble of the brook Warbled out these metres meet: "Love seeketh only self to please, To bind another to its delight, Joys in another's loss of ease, And builds a Hell in Heaven's despite."[/fieldset] In literary fiction, an antithesis can be used to describe a character who presents the exact opposite as to personality type or moral outlook to another character in a particular piece of literature. Some examples of an antithesis in popular literature include the characters of Dumbledore and Voldemort in Harry Potter and Aslan and the White Witch in "The Chronicles of Narnia".
