" The philosophy of individualism owes a great deal to the tradition of novel-writing and novel-reading. In its development and in its aesthetics, the novel is not politically neutral; it has been a participant in history all along. "
- Sally Rooney

In simple terms, the quote suggests that literature, particularly the tradition of writing and reading novels, has played a significant role in shaping individualistic philosophies. It argues that novels are not merely passive reflections of societal norms but have actively participated in historical and cultural developments by influencing how individuals perceive themselves within society.

On a deeper level, this statement highlights the profound impact of literature on both personal identity formation and broader social structures. Novels often delve into the complexities of individual human experiences and relationships, which can challenge or reinforce prevailing social norms and ideologies. By portraying characters who grapple with their identities in various contexts, novels contribute to evolving notions of selfhood and independence. This interaction between literature and societal change underscores how creative works can be catalysts for political and cultural shifts.

The quote is from Sally Rooney, an Irish novelist known for her contemporary fiction that often centers on the lives of young people navigating issues related to love, politics, and social class in modern Ireland. Her work frequently explores themes of personal identity within larger societal frameworks, aligning with the idea she expresses about literature's role in shaping individualistic thought.
