In short, he was a dope. He often looked to Yossarian like one of those people hanging around modern museums with both eyes together on one side of a face. It was an illusion, of course, generated by Clevinger's predilection for staring fixedly at one side of a question and never seeing the other side at all.
The character Clevinger from "Catch-22" is portrayed as someone who lacks depth and comprehension. Yossarian views him as rather foolish, drawing a parallel to individuals who appear distorted in a museum, suggesting that Clevinger's perspective is skewed and insufficient. His tendency to focus on a single aspect of any issue prevents him from seeing it in a broader context.
This description highlights a key theme in Heller's novel about the limitations of rigid thinking. Clevinger's inability to consider multiple viewpoints symbolizes the challenges faced by individuals who cannot grasp the complexity of situations, leading to a disconnect from reality and understanding.
