Prompt
Generate an image of a middle-aged American man from the early 20th century, sitting in a library or study with books and papers around him, wearing glasses and a suit, with a thoughtful expression on his face. The style should be realistic, and the setting should reflect his profession as a philosopher and logician. Include some symbols or diagrams of logic in the background to hint at his work in the field. The man should be Clarence Irving Lewis, and the image should convey his intellectual and contemplative nature.
