The Unbearable Lightness of Being is an existentialist novel by Milan Kundera centering around Tomas, a Czech intellectual living at the time of the Soviet invasion in 1968. Tomas is a womanizer, regarding sex and love as separate entities, and maintaing an extramarital affair with his friend Sabina. His wife, Tereza, fears, though begrudgingly tolerates, Tomas' infidelity. The book's central philosophical questions lie in the tension between lightness, associated with caprice, and heaviness, associated with commitment.
