Big Ideas Library

Some of the most important books ever written look scary on a real shelf. Each cover here opens an explainer full of pictures and games, so when you pick up the real paperback, you already know the way. And no book stands alone: the latticework shows how they fit together into one way of understanding the world.

How it all fits together

A latticework of big ideas

Charlie Munger said the wisest people carry a latticework of mental models: big ideas from many subjects, linked together. These 20 books do just that. Each one teaches several big ideas, and each idea appears in several books. Psychology meets history, money meets evolution, and technology meets politics. Put together, they form one framework for how nature, minds and societies work.

How to read a hard book

Six tricks that work

1 · Map first

Explore the explainer first. Knowing the big idea makes every chapter easier.

2 · Don't start at page 1

Big non-fiction isn't a novel. Start with the chapter that interests you most.

3 · Twenty pages a day

That finishes a 400-page book in three weeks.

4 · Read with a pencil

Underline one surprising sentence per page. Write one question in the margin.

5 · Follow a thread

When a book mentions an idea from another, jump across. That's how knowledge grows.

6 · Argue with the author

Every explainer ends with the book's critics. Decide who you agree with.

The explainers summarize each book in simple words for learning. They are not copies of the books and don't replace reading them. Page counts are approximate. Progress is saved only in this browser.
