"I do not now fool myself, to let imagination jade me..." 'Twelfth Night suggests that the worst deception of all is the one we practise on ourselves.' Discuss.

Written amid the Elizabethan festival of Epiphany, a night of licensed misrule when servants mocked masters and the rigid Tudor hierarchies of class and gender were briefly upended, William Shakespeare's Renaissance romantic comedy Twelfth Night (c.1601) explores the beguiling and foolish nature of self-deception.¹ In it, while Shakespeare initially highlights how self-deception, when built on idealised fantasy and self-regard, distorts judgement into a kind of folly, he proceeds to challenge such vanity as individuals who love with patience and self-awareness ultimately achieve genuine union.² Indeed, Shakespeare highlights how self-flattery transforms judgement into a sickness of the mind. However, Shakespeare depicts individuals resorting to fantasy and deception in an attempt to manage a world unhinged by folly. Ultimately, despite the efforts of those who seek to cure their self-deception through disguise and scheming, Shakespeare concludes that only those who relinquish self-love are rewarded, leaving the deluded to their "imagination".³

Initially, Shakespeare exposes how melancholic self-absorption transforms self-flattery into an obsessive folly, also revealing how unchecked ambition allows love to curdle into self-deception.⁴ Opening on the languid command "If music be the food of love" before demanding "Give me excess of it", Orsino frames his own lovesickness through the language of gluttony, surrounded by "Musicians attending" upon his private grief to demand a soundtrack to satiate his self-deceiving lovesickness. Confessing a fancy "so full of shapes" that reality cannot rival "fair Olivia", the Illyrian ruler views himself through the Petrarchan conceit of being "turn'd into a hart⁵", a self-mythologisation that disguises indulgent egotism as helpless victimhood. Drawing upon romantic melancholy through Elizabethan humoral theory, where "liver, brain and heart" surrender their sovereign thrones to fancy before the playwright brands such indulgence "high fantastical", Shakespeare satirises aristocratic courtship, implying Illyrian anguish is privileged boredom masquerading as folly. Where Shakespeare depicts the languishing nobleman consumed by the idea of love rather than its object, he further elucidates how the same self-regard drives the puritanical steward to mistake fantasy for reality.⁶ Recognising her extreme vulnerability as stranded noblewoman without her brother Sebastian, Viola petitions the Captain to "conceal me what I am⁷," a plea whose carnivalesque inversion exposes disguise as deliberate strategy to present a "fair and outward character", in which Shakespeare underpins a friction between social masks and inner selves. In viewing her flight as "mine own escape" before requesting to be presented "as an eunuch," she doubles the era's own convention of boy actors playing women, so the all-male stage renders her gender concealment a layered, self-referential deception the audience alone can see. Thus, resolving to "serve this duke," Viola tethers to a fabricated identity so private grief for Sebastian is subsumed by public performance, with Shakespeare demonstrating how deliberate fabrications trap their disguisers in self-deceiving deadlocks that defy easy resolution. Thus, it is only when self-indulgent longing combines with a wilful refusal to see others clearly that vanity descends into the self-deception that grips Illyria.⁸
