## Why am I passionate about this?

Most of my books (*101 Philosophy Problems, Wittgenstein's Beetle, Critical Thinking for Dummies,* and so on) are on thinking skills, in the broad sense. However, I'm always a bit uncomfortable when I'm presented as an expert on thinking, as people tend to imagine I must have some brainy strategies for thinking better when my interest is also in the ways we "think badly." Because logic is really a blunt tool, compared to the brilliant insights that come with intuition. Yet how do you train your intuition? So the books I've chosen here are all ones that I've found don't so much tell you how to think, but actually get you thinking. And that's always been my aim in my books too.

## Martin's book list on thinking skills

### Why did Martin love this book?

Raymond Smullyan is a riddler, a puzzler, well-known for various Knights and Knaves puzzles, a type of logic game where some characters can only answer questions truthfully, and others only falsely. However, I recommend this book as here he offers not only logical tricks but many insights too. One section offers the World's shortest explanation of Gödel's theorem which is a magnificent achievement but frankly, reminds me why I like long explanations sometimes.

Basically, this is an examination of boolean logic, which is (rather boringly) a branch of algebra in which all operations are either true or false, and relationships are expressed with logical operators such as *and, or, *or* not*. So it’s serious stuff, but also pretty funny along the way.
