+The excerpts contain several passages that quote or reference Louis Menand, particularly focusing on his ideas about hypostasis 
+and the human relationship with concepts such as God and societal structures. Here are the relevant passages:
+
+1. **File: ./data/2025-11-04.txt**
+   - This excerpt includes the quote: "We created God, and then pretended that God created us. We hypostatized our own concept and 
+turned it into something 'out there' whose commandments (which we made up) we struggle to understand and obey. We are supplicants 
+to our own fiction." It discusses the parallels between this idea and other societal constructs like democracy and politics.
+
+2. **File: ./data/2025-02-14.txt**
+   - The passage reiterates Menand's quote about hypostasis and emphasizes how humans have created a sense of distance from their 
+own creations, allowing for worship or rebellion against them. It reflects on the implications of this process for understanding 
+reality and human experience.
+
+3. **File: ./data/2022-08-14.txt**
+   - This excerpt discusses Menand's "Free World," specifically pages 335-339, where he critiques how people perceive external 
+forces as inevitable, which are actually human creations. It includes the same quote about God and hypostasis, highlighting the 
+idea that these constructs are reified as "the way things are."
+
+4. **File: ./data/2025-07-27.txt**
+   - This excerpt references Menand's quote in the context of discussing anti-capitalist themes and the narratives that organize 
+society, emphasizing the fictional nature of these constructs.
+
+5. **File: ./data/2025-02-05.txt**
+   - Here, Menand's notion that we are "supplicants to our own fictions" is paraphrased, relating it to the broader role of 
+storytelling in human culture and how we create and live by the narratives we construct.
+
+6. **File: ./data/2024-09-04.txt**
+   - This excerpt mentions Menand in the context of discussing AI and copyright, though it does not quote him directly. It
