At the end of chapter 1, the eponymous Candide shares a passionate kiss with the beautiful Cunegonde. The kiss is obviously very passionate and heartfelt because "their knees trembled" and "their hands strayed." The Baron, who is Cunegonde's father, happens to be walking past when Candide and Cunegonde are kissing. He becomes outraged that Candide should dare to take such a liberty with his daughter, and in his own castle, too. By way of punishment, he expels Candide from the castle. Candide is chased from the castle "with great kicks on the backside."
This expulsion from the castle represents for Candide an expulsion from paradise. He considered his life in the castle a paradise in large part because he could see the beautiful Cunegonde every day and also because he could listen to Master Pangloss, supposedly "the greatest philosopher of the ... whole world," every day.
Just as Adam and Eve are expelled from the Garden of Eden, so too Candide is expelled from his own paradise. In drawing the comparison between the two stories, we might infer that Voltaire is satirizing the Garden of Eden story. Voltaire has Candide violently expelled from the castle as a result of the Baron's own excessive pride. Perhaps Voltaire is suggesting that God likewise was guilty of excessive pride when he had Adam and Eve expelled from their paradise. This critical, satirical approach to the God of the Old Testament would certainly be consistent with Voltaire's other writings.
