Sometimes it seems that one of the largest, vastest, most complex kinds of realm in all human experience is the realm inside our minds, so you'd think there'd be at least as much said and written about that as about our planet or the universe. But actual literary explorations of it are pretty sparse – just people talking, for one reason or another, about swimming or poking about in one's mind, in their own words. (There are concrete terms related to minds – nerves, neurons, lobes – but since we experience those things subjectively, people presumably have to use their own words.)

Fortunately, as I discovered when I was finally able to borrow the audiobook from the library: this book by Cleese is one of those. Saying Cleese is widely considered creative feels similar to saying Mozart is widely considered to be a musician – it's not even a question. Illustratively, the audiobook begins not with Cleese's voice uttering the first heading, but with Cleese introducing himself and saying he's about to read the book. ("The first heading is…") This would seem mundane if this wasn't the first audiobook I've ever encountered delivered that way. (He notes upon closing that he's not sure why he recorded it since reading it only takes an hour, but "perhaps some of you can't read.")

Anyway, the book is indeed about being more creative, and the basic concepts conveyed – really a small number of concepts – while backed by study, are indeed personal and reflective. That's what I meant by seeming to yearn for people's "own words" earlier: this book, like many unwritten books that must deserve to be written, could only have been written by its author.
