Motivated by the insights of Karen Horney into submissive and compliant personalities, this study delves into the perpetual vulnerability, fear of helplessness, and isolation portrayed in James Joyce’s A Portrait of the Artist as a Young Man through the lens of psychoneurosis theory. Individuals with obsessive appeasement tendencies experience excessive dependency and restlessness, reinforcing their feelings of helplessness and often resulting in manipulative attachments to powerful figures and self-defeating behaviours. Neurosis amplifies these maladaptive responses, intensifying anxiety stemming from individual, familial, social, or religious fears, thereby significantly impacting social functioning. This study aims to analyse the submissive personality of Mary Dedalus in Joyce’s novel from the three distinct perspectives of need for approval, sense of unsupportedness, and fear of the church. An in-depth exploration of these aspects not only enriches our comprehension of Joyce’s work but also offers valuable insights into the portrayal of neurosis and its impact on human behaviour within a competitive societal framework.
