“To make knowledge practical we must convert it into rules of operation. **We must pass from knowing what is the case to knowing what to do about it if we wish to get somewhere**. This can be summarized in the distinction between knowing that and knowing how. **Theoretical books teach you that something is the case. Practical books teach you how to do something you want to do or think you should do**.” ([Location 996](https://readwise.io/to_kindle?action=open&asin=B004PYDAPE&location=996)) --- **Tags** -- [[quotes]], [[reading-books]], [[Richard Feynman]], [[analytical-reading]] **Source** -- [[20250103084100 - B - How to Read a Book]]
