Follow the principle of the heart

The principle of following the heart when it overcomes reason is the ethical maxim Nérine gives Cléante when his love for Nisida collides with his obligation to return to his regiment. It first appears as advice to acknowledge the force of genuine feeling rather than submit automatically to prudence, but the surrounding plot complicates it: love may justify courage and disclosure, yet it does not erase duties toward family, truth, or property. By the conclusion, the principle survives only within a broader morality of honesty, gratitude, and paternal responsibility.

Nérine’s Counsel

Nérine presents the rule while reminding Cléante that she alone enabled his access to Arlequin’s household and protected his love for Nisida. She asks him to examine himself honestly. If he can forget Nisida, he should return to his regiment, resume his service, and recover through merit the position that fortune has taken from him. If he cannot live without her, he should remain rather than die inwardly, speak to her, reveal his identity, and confess his love. The principle therefore begins not as an invitation to impulsiveness but as a demand for self-knowledge: Cléante must determine whether his passion is temporary or stronger than the life expected of him.

Nérine’s advice is also practical. She claims to know more than Cléante does and treats his happiness as a personal concern. When he asks what to do, she directs him to write to his colonel and request a month’s delay, while she undertakes to bring Cléante and Nisida to an explanation. The maxim thus becomes a plan: postpone the external obligation, create a short interval for emotional truth, and let action follow the heart’s actual strength rather than an abstract command.

Love Against Duty and Concealment

Cléante’s situation makes the maxim difficult because his love has depended on disguise. He entered Arlequin’s house as a secretary after failing to find another way to approach Nisida, and Nérine helped him assume that role. For six months he has lived near Nisida, seeing her daily and speaking with her occasionally while she remains unaware both of his love and of his claim to be worthy of her. His attachment is therefore sincere, but its conditions are deceptive. Following the heart requires him to disclose himself, while disclosure threatens the fragile happiness that concealment has provided.

Nérine searches for evidence that Nisida’s feelings answer Cléante’s. She reports finding Nisida shut inside her cabinet, playing the guitar and singing Cléante’s song softly, with an unmistakably tender accent. In Nérine’s reasoning, someone indifferent to an author would not hide away to sing his song in a low voice. This observation converts private feeling into a basis for action: Cléante’s heart need not move blindly, because Nisida’s solitary song suggests that his love may be reciprocated.

The Rule Tested by Sacrifice

The principle does not lead every character to pursue personal happiness. When Arlequin proposes a marriage that threatens her love, Nisida declares that she will do her duty, asks for the marriage to be delayed, and requests permission to enter a convent. Her obedience becomes more determined as paternal command increases: the less her father orders, the more she wants to obey. She treats renunciation as a service owed to him and as a means of securing the peace of his life.

Nisida later makes the sacrifice explicit. Because Arlequin has done more for her, she believes she must do more for him; she will overcome and immolate her passion for the happiness of his old age. She asks to be separated from Cléante and offers to marry the marquis d’Yrville. Her response exposes the tension within the maxim. The heart may identify the beloved, but moral feeling can also take the form of self-denial when love for a parent is judged to require it. Arlequin refuses that proposed marriage, yet his refusal does not immediately dissolve the conflict: he still sees Nisida’s passion as an illness and himself as the physician responsible for curing it.

Disclosure and Moral Consequence

Cléante eventually follows the path Nérine urged. He tells Arlequin that a deep passion for Nisida has possessed him for more than a year and admits that he presented himself as a secretary because he despaired of entering the household otherwise. He calls these acts his crimes and submits himself to punishment. His confession transforms the rule from private romantic advice into a public ethical test. He has chosen truth even though the truth exposes his disguise and places his love under Arlequin’s authority.

Cléante explains that his hope had been to please Arlequin by living with him, win his esteem and kindness, and wait until affection made the confession possible. He imagined that his poverty and misfortunes, once disclosed to a sympathetic friend, might become reasons for hope rather than barriers to marriage. His strategy shows why concealment was not merely opportunistic: he wanted Arlequin to judge him as a human being before judging him as a suitor. Yet the strategy still violates the household’s trust, and the consequences are immediate. Arlequin orders him to leave at once, embraces him, swears eternal friendship, and forbids him to appear there again.

Honesty Beyond Personal Happiness

The final revelation places the principle of following the heart inside a larger moral order. Arlequin identifies Cléante as the son of the man who had left the family its fortune and declares that Cléante is the rightful owner of everything they possess. The household is rich in the morning and faces poverty afterward, because Arlequin believes the property must be restored; otherwise they would no longer be honest people. The decision gives legal and material force to the emotional drama, but its stated basis is moral rather than advantageous.

The ending does not simply reward passion with wealth. Arlequin accepts that Cléante and Nisida will be united, doubles the dowry originally intended for Nérine, and asks her to remain as the family’s good friend. He then defines the highest pleasure as fulfilling the duty of an honest man and a good father. The heart has led Cléante toward Nisida and brought hidden truth into the open, but the play’s final judgment requires that love coexist with honesty, gratitude, and paternal care. Feeling supplies the direction of action; moral character determines whether that action can be worthy of its desired happiness.
