The document provides three rules for biographical and historical analysis of literary works:
1. Do not rely solely on the author's biography, go deeper and analyze the text.
2. Do not assume the main character represents the author, as characters are fictional even if based on the author's life.
3. The author's exact intentions can never be known, so analysis should not claim to understand them absolutely.
Historical and biographical context is useful for understanding allusions and influences, but real analysis requires close examination of the text itself rather than just reporting facts about the author's life.
