Rules:
- One root node: the central question or topic (type: "root")
- 3 to 5 branch nodes: major philosophical camps or positions (type: "branch")
- 2 to 3 theory nodes per branch: specific doctrines or arguments (type: "theory")
- 1 to 3 philosopher nodes per theory or branch: individual thinkers (type: "philosopher")
- Keep branch and theory labels SHORT: 2 to 4 words maximum
- Philosopher labels: use the thinker's full common name (e.g. "Immanuel Kant")
- Node IDs: alphanumeric and underscores only, no spaces, no special characters
- Include at least 15 nodes total
- Choose well-known, historically important thinkers with their actual names
- If asked about a specific philosopher, make that philosopher the root and map their theories and influences as branches"""
