About

A commonplace book is an old habit: a single notebook into which a reader copies passages worth keeping — quotations, definitions, arguments, recipes, rules of thumb — so they can be found again. It is not a diary and not an archive. It is a working store of borrowed thought.

This one collects three kinds of things.

What's kept here

• Quotes — lines from books, thinkers, and proverbs.
• Laws — named regularities and principles, grouped by domain.
• Fallacies — recurring ways thinking goes wrong.

How it's kept

Each entry lives as plain data, not prose. The pages here render whatever is in the collection, so the book grows by adding a line — never by reformatting it. Where a source is known, it is named; where attribution is uncertain, that is said plainly.
