In A.S. Byatt's exploration of Iris Murdoch's early novels in "Degrees Of Freedom," she highlights the importance of understanding the complexity of human nature. Murdoch emphasizes the idea of the 'opacity of persons,' suggesting that individuals are multifaceted and cannot be easily understood or reduced to simple concepts. This notion is pivotal both in philosophical discussions of moral values and in the development of characters within the narrative.

Byatt's analysis showcases how this idea of opacity informs Murdoch's literary style, allowing her characters to embody a rich, intricate reality. Rather than providing clear resolutions, Murdoch invites readers to engage with the ambiguity and depth of her characters, encouraging a deeper reflection on the human condition and relationships. This approach resonates with both liberal moral thought and the art of novel writing, making her work significant in literary studies.
