"Collected Works of Gide" includes Gide's three masterpieces: "The Narrow Gate", "The Irregulars" and "The Food of the World". The Food of the World is a collection of essays by Gide. After Gide traveled to North Africa and Italy, he used his wanderings on the road as a clue and used a virtual goddess as the object of his confession to express his feelings about life. He wrote a series of poetic fragments that were combined with traditional short poems, odes, melody and other forms. Gide despised traditional morality and advocated freedom of individual behavior. He especially emphasized people's strong feelings about nature and life, and used this feeling as spiritual food.
