Recognize Fundamentals

---

In any field of study, identifying the true fundamentals can be challenging. But there are two reliable tests that can guide us.

First, fundamentals have stood the test of time—they've persisted while trends and fashions have faded.

Second, fundamentals serve as building blocks: from them, the entire field can be constructed using standard methodologies.

These twin characteristics—longevity and generative power—separate the essential from the peripheral. When you find concepts that have endured for generations and from which complex ideas naturally flow, you've likely discovered the bedrock principles upon which deeper understanding can be built.
