About the Translator
Michael Henry Heim (1943–2012, 1984, Harper Perennial): Professor of Slavic Languages and Literatures at UCLA; one of the most important literary translators of the twentieth century, working from Czech, Slovak, Russian, German, Dutch, Croatian, and Hungarian. His other translations include Bohumil Hrabal's I Served the King of England, Anton Chekhov's letters, and Günter Grass's The Tin Drum. Kundera collaborated intensively with Heim on the English text, eventually coming to consider the translation a co-authored work; current Harper Perennial editions credit Kundera as sole author without a translator byline — an unusual situation reflecting both the closeness of the collaboration and Kundera's strongly held views about authorial primacy over translation.
Themes
Lightness and weight. The novel opens with a philosophical question drawn from Nietzsche's doctrine of eternal recurrence: if every moment returns infinitely, each choice carries infinite weight; if each moment occurs only once, nothing returns and therefore nothing truly matters. Kundera's four characters embody different positions on this spectrum. Tomáš is constitutionally light — uncommitted, unfaithful, free — and his love for Tereza is the weight that threatens his lightness. Tereza is heavy — burdened by her body, her jealousy, her dreams. Sabina cultivates lightness as a philosophical position. Franz confuses lightness with freedom and weight with meaning. The novel refuses to resolve which is better; both are, in the end, unbearable.
History and powerlessness. The Prague Spring of 1968 and its suppression by Soviet tanks in August of that year is the historical event around which the novel's private lives are organised. Kundera depicts his characters as profoundly unable to affect the historical forces that shape their lives: the invasion happens, people are photographed by the secret police and lose their jobs, emigration becomes necessary. The political is never absent, but it is also never sufficient — the novel insists that private life and its entanglements are where human beings most essentially live, regardless of the historical epoch crushing them.
The body, the soul, and the dream. Tereza is the novel's most fully realised study of the relationship between body and soul. She is unable to dissociate herself from her body in the way Tomáš dissociates himself from the bodies of his many lovers; she experiences his infidelities as violations of her own body even when her mind understands his reasons. Her recurring dreams — analysed by Kundera with the attention of a novelist who has also read Freud — are the most direct expression of what she cannot say or know while waking.
Key Characters
Tomáš — a surgeon and incorrigible womaniser who loves Tereza despite himself; his formula "love her but sleep with others" is the novel's central emotional paradox. His lightness is a philosophical position he cannot maintain once Tereza arrives; his inability to abandon her is the weight he cannot escape.
Tereza — a provincial waitress whose chance arrival in Tomáš's life via a novel and a coincidence he reads as destiny; the embodiment of weight, attachment, and the refusal of dissociation. Her jealousy is not a character flaw but a philosophical position: she insists that love and fidelity are inseparable, and the novel presents her position with full sympathy even as it presents Tomáš's with equal understanding.
Sabina — Tomáš's long-term mistress and a painter; the novel's most fully theorised embodiment of lightness and its pleasures. Her relationship with Franz, and her systematic betrayal of every commitment she makes — not from cruelty but from a principled refusal of kitsch and compulsion — constitute the novel's second major narrative strand.
Franz — a Swiss academic who falls profoundly in love with Sabina; his understanding of her is built entirely from misconceptions. He represents the European intellectual left's romanticism about Eastern European dissidence — he joins the March of Triumphal Return, a demonstration that takes protesters to the Cambodian border, and is killed there by a mugger, in an ending the novel handles with characteristic black comedy.
Karenin — Tereza and Tomáš's dog; named after Anna Karenina's husband. His illness and death in the novel's penultimate section constitute one of its most affecting passages, and Kundera uses Karenin to develop the novel's deepest meditation on unconditional love and what it means that human beings are capable of it with animals in a way they rarely are with each other.

There is only one English translation of The Unbearable Lightness of Being. Michael Henry Heim's text — revised extensively in collaboration with Kundera, who came to regard it as a co-authored work — is the translation through which the novel reached its global audience. Current Harper Perennial editions do not credit Heim by name, reflecting Kundera's own wishes about the primacy of the author over the translator. There is no alternative English version, and none is expected.
