I wouldn't recommend it either, it is a very simplistic view of coding with some bad advice intermingled. Obviously reality is much more complex than any book could describe and there is benefit to think about bad examples as well as good ones.

Though it is an ill-defined term clean (clear, readable, reasonable, understandable) code is important in the sense that accidental complexity should be minimized and encapsulated and necessary complexity should be understandable.
