The narrative traces the life of a sensitive orphan, Philip Carey, from a precarious childhood through adolescence and early adulthood as he seeks purpose amid physical frailty, strained relationships, and uncertain ambitions. He alternately pursues medical studies and artistic training, experiences thwarted desire and a destructive obsession with a woman, and endures poverty, failure, and disillusion. Through intimate psychological detail, the story examines freedom and compulsion, the interplay of passion and reason, and the slow cultivation of self-understanding that leads toward acceptance and a quieter moral resolve.
