Start with what's going on right now. Pick a theme – and we'll show you the books that speak directly to it.

Each book is broken down into its core ideas – in sequence, with explanations, real-world examples and cross-references to other books that agree or contradict.

Every idea has a counterargument. We show you both. Read critically – don't take any book at face value, including the ones we recommend.

After reading the ideas you'll know whether this book belongs on your shelf. If it does, buy it. If not, move on – no time wasted.
