PositiveNPRSeven Brief Lessons does not shy away from philosophy and it is an admirable testament, I think, to the fact that philosophy and natural science, although perhaps never one and the same, must grapple with each other. None of Rovelli's 'lessons' left me satisfied. But in a good way. They all left me wanting more ... Rovelli's is a beautiful book and I recommend it. But I warn the reader, and I warn him: If he is right that we belong to the very same nature it is the project of physics to understand, then it may be that there is something incomplete or not yet adequate in our physics itself. For we have nothing like an adequate account of ourselves in the natural world.
