'The Road to Maxwell's Demon is an exceptionally clear and readable book, intended for readers without physics or philosophy backgrounds. It is also a highly original and important contribution to the foundations of physics. It goes against much of the received wisdom and offers novel solutions to many problems: among them, discussions of time asymmetry in classical mechanics, an empiricist alternative to typicality, a criticism of the role of ergodicity, the notion of a physical observer and the irrelevance of information theory to the foundations of statistical mechanics. Readers interested in the foundations of physics will welcome such a fresh outlook on these topics.' Amit Hagar, Metascience
