In "The Oasis," Mary McCarthy explores the pervasive feelings of boredom and urban cynicism in modern life. The characters become so accustomed to these negative emotions that they struggle to appreciate moments devoid of such qualities. This highlights the challenges of finding genuine enjoyment in experiences when one is surrounded by a culture of disillusionment.
McCarthy suggests that this adaptation to cynicism and monotony leads to a warped perception of reality, making anything free from these traits seem unusual or lacking. In essence, the characters' inner turmoil reflects a broader societal malaise that complicates their ability to embrace joy and fulfillment in their lives.
