One morning in June, Alain is walking on a street in Paris and sees a lot of women wearing low-waist trousers, baring midriffs. Alain is fascinated by their bare navels, but he is confused at same time. Woman's thighs or breasts are no longer the modern eroticism, but woman's navels are the center of temptation. What does it mean? This is the beginning of the novel. "The feast of insignificance", is composed as a piece of ridicule comedy, mainly played around a scene of greenery, the garden Luxembourg, which welcomes the steps and conversations of four friends: Alain, Ramon, Charles and Caliban. From corridors of Luxembourg to a strange party, these four characters talk serious things with lightness: Kant, the former USSR, and seduction techniques are some of the issues evoked by author in this exquisite fugue around insignificance - a celebration of intelligence.
