Au XXème siècle, marqué par une sensibilité particulière au tragique et à l’absurdité du monde, un puissant rameau d’écrits au fond desquels résonne le désir du bonheur qu’on trouve ici et là, dans des éléments variés, se trouve grandi et fleuri. Le but de certains écrivains est d’exposer leur propre conception. Parmi ces écrits, les œuvres de Jacques Chardonne. A partir de sa propre expérience et de son regard sur les autres, Chardonne traite du bonheur dans deux types d’écrits : romanesques et non romanesques. Dans le premier il parle spécialement du bonheur dans la vie à deux. Il attache une grande importance à chercher les figures de ce bonheur : ce qui fait le bonheur conjugal, comment l’atteindre et quels sont les facteurs qui peuvent le perpétuer. La femme et ses caractéristiques sont le pôle principal de ce bonheur. L’amour est essentiel, il « est beaucoup plus que l’amour ». Pourtant c’est la satisfaction du personnage qui rend ce bonheur accompli. Des obstacles peuvent empêcher le personnage d’atteindre ce bonheur, mais l’adoption de certains procédés narratifs aide Chardonne à sauvegarder dans ses écrits les traits du bonheur.Une série des œuvres non romanesques, œuvre autobiographique et essais parlent de ce qui fait le bonheur dans la vie de Chardonne : son enfance dans sa ville natale, Barbezieux, au milieu de gens toujours heureux, l’amour partagé, l’amitié, le métier et les beaux paysages découverts pendant ses voyages dans sa vie d’adulte, ainsi que son petit jardin à la vieillesse. Un peu de regret et les souvenirs de son séjour dans la prison de Cognac à la Libération troublent la vie paisible de Chardonne. La philosophie qui traduit un acte de volonté intérieure, « Cela m’a suffi » dont s’est réclamé Chardonne pendant toute sa vie, rend le bonheur un état permanent dans tous ses écrits comme dans sa vie. / During the 20th century era, when the tragedy and the absurdity were dominant; a series of writings which were interested in happiness and pleasure, that here and there, in varied elements, flourished. The aim of most authors was to demonstrate their personal ideas and perceptions of happiness. One of these compositions was the collection of Jacques Chardonne. From his personal experience and his vision at the others, Chardonne discusses happiness in two types of writings: fictional and non fictional. In the first category he speaks specifically of happiness in life to two. He attaches great importance to find the figures of this happiness: the strategies which help to achieve it, and the factors which can perpetuate it. From his view, the woman and her characteristics are the pole essential of this happiness. Also the love is essential. It "is much more than love". Yet, it is the author's satisfaction that restores this happiness perfect. In his writings, although there are some obstacles which may prevent full achievement of happiness, yet Chardonne was able to overcome most of them by adapting a special narrative strategy to keep the sense of happiness in the general atmosphere.A series of non fictional writings, autobiographic story and trials, talk about the elements of the happiness in Chardonne’s life. Some are related to the happy childhood, in his mother country, Barbezieux, where he lived and brought up with happy people; as well as the mutual love, the good friendship, his career, and the enormously beautiful views in the trips during his youth, and the small garden during his senility. However, there are some regrets and his memories about the time that he spent in the prison of Cognac during the Liberation disturb the quiet life of Chardonne."This satisfied me" was the philosophy that had been adapted by Chardonne throughout his life, which can be translated as the interior will and desire which built up the persistent feeling of happiness reflected in all of his writings.
