Hugo's line "Demain j'aurai froid sous la terre froide" from Les Contemplations places the warmth of the living "demain" against the cold of
the grave in a stark antithesis that captures grief's essential
paradox; Racine builds his entire tragic vision on antithesis, opposing duty and desire, reason and passion,
light and
darkness throughout Phèdre: "Je le vis, je rougis, je pâlis à sa vue" contrasts blushing and
pallor in a single line; Corneille's Le Cid turns on a sustained antithesis between love and
honor, crystallized in Rodrigue's famous stanzas where each hemistich opposes the demands of the heart and the demands of family
glory; A student practicing antithesis might write "La guerre est douce à ceux qui ne la font pas" using the contrast between the sweetness of
distance and the bitterness of experience to capture the gap between imagination and reality; Baudelaire's "
Spleen et Idéal," the governing antithesis of
Les Fleurs du Mal, structures the entire collection around the
opposition between earthly degradation and spiritual aspiration, making antithesis a structural as well as a local device; In classical rhetoric, the antithesis is most powerful when the opposing terms occupy symmetrical positions
within the line or couplet, so that the formal balance of the verse enacts the conceptual opposition of the ideas.
