Prompt
Create an image of Thomas Nagel, a middle-aged man with a contemplative expression, sitting in a library or study surrounded by books, with a subtle hint of a philosophical introspection. He should be dressed in casual yet intellectual attire, possibly with a pair of glasses and a slight smile. The background should feature shelves with books, possibly with some philosophical texts visible, and a window with a blurred view of the outside. The style should be realistic, with a muted color palette that conveys a sense of intellectualism and introspection. The image should capture the essence of a philosopher and author who has spent his career exploring the human experience.
