## The Technique: Fourier Transform + Low-Pass Filter

| Step | Description |
|------|-------------|
| **Input Signal** | Zhang Zai's "Four Sentences" — grand philosophical ideals about serving heaven, the people, sages, and all future generations |
| **Fourier Transform** | Decompose the signal (rhetoric) into its frequency components |
| **Low-Pass Filter** | Strip out the high-frequency, ornate, "florid" high notes — i.e., the noble-sounding surface language |
| **Output Signal** | The low-frequency, fundamental baseline — the raw, honest motivation underneath |

## The Punchline

> **"我要当官！"** *(I want to be an official!)*
> *(then repeat 3 times via convolution with an impulse sequence)*

- The "main melody" that remains after filtering is simply **personal ambition for power/status**.
- The convolution repetition (`×3`) mimics how this desire echoes persistently — it is the dominant, recurring theme.

## Key Insight (Skill Extracted)

**When analyzing grand rhetoric, apply a conceptual "low-pass filter":**

1. Ignore high-frequency ornamental language (moral grandeur, poetic flourishes).
2. Identify the **low-frequency core signal** — the persistent, fundamental human drive.
3. The true motivation is often far simpler and more self-serving than the surface expression suggests.

**Application:** Useful for media literacy, political speech analysis, corporate mission statement critique, and any context where elevated language may obscure self-interest.
