Frank McCourt’s Angela’s Ashes chronicles McCourt’s childhood in Irish slum where he encounters various kinds of predicament and how he keeps a positive thinking in bitterness; eventually he achieves his goal—American dream. His winning Pulitzer Prize marks the highlight of McCourt’s long and painful maturing process from childhood. His struggling process illustrates many valuable educational lessons of the prestigious psychologist Abraham Maslow. In this thesis, I would like to use Maslow’s theory of Hierarchy of Needs to delineate the transformation of process of the protagonist in Angela’s Ashes, Frank McCourt. This thesis is divided into five chapters. The opening chapter introduces Frank McCourt’s background and scholarship. Also, it compares the similarities and differences of writing style between Frank McCourt and two notable Irish writers—Oscar Wilde and James Joyce. Chapter Two presents a brief framework of Maslow’s Hierarchy Needs. Maslow’s hierarchical structure of human needs enlightens the protagonist’s transformation process from a seemingly hopeless child in a slum to a fully developed and independent man. It also indicates the transformation process how Frank McCourt upgrades himself from a physical laborer to an intellectual. Chapter Three analyses the key persons who have strong impacts on Frank McCourt. First two are Frank McCourt’s parents. Frank McCourt experiences the roller caster of complex emotions toward his parents. However, he still holds many legacies from his parents. Then, he comes across four substitute fathers. Each substitute father acts as a role model who affects him in different aspects. The last but not least are two puppy lovers. Chapter Four studies four key factors in public domain. These factors contribute to different effects and show vividly the ideological conflicts in Frank McCourt’s thoughts. They are school, society, religion and nationalism respectively. At school, young McCourt is detected to have a gift of writing. In society, he notices that he suffers from class discrimination. Ultimately, the powerful Catholicism and overarching nationalism dominate his childhood, but Frank McCourt keeps a paradoxical attitude to these two factors-both revered and reviled. The conclusion chapter gives some pedagogical reflections from my experience in teaching young students from disadvantaged families. Finally, it concludes with the faith that Frank McCourt’s struggling process brings to those disadvantaged children and young people.
