The purpose of this study is to examine Gide`s thoughts on the novel and their formations in Les faux-monnayeurs. The author defines this novel as the only novel genre among his works. He wanted to include everything he experienced in life in this work and tried to remove the impurities and leave only the essence in it. Firstly we learned in this study that according to Gide the essence of the novel is first of all in tension and competition between showing reality and stylizing it. The author does not lead a personage or a story in a predetermined direction in his work, but instead writes a novel as experience teaches. He emphasizes that the novel must pursue a closer approach to nature. Attempting to construct a new novel based on mise en abyme, such as inserting a novel in this novel and applying characteristics of polyphonic music to it, Andre Gide wants to show that the novel is not a closed area, but an open one with infinite potential. Through the meaning of the title of the work `counterfeiters,` Gide criticizes the hypocritical attitude of pursuing honor and profit in the present. He emphasizes that a true writer should pursue novels worthy of being read again, overcoming the temptation to gain popularity and honor from the current readers. In the sense that it is a novel that shows the process of the creation of a novel to be born in the future, and that the end of the novel is anticipating a new opening, Gide`s work shows a future novel that does not stay in the past. This novel is a pioneering work that anticipates future novels in that the innovative attempt in this novel inspires the tendency of the Nouveau Roman seeking a new identity in modern novels in the mid to late 1950s.
