We tend to think of the way we live as "reality". Yet all human culture - from the smallest object to the grandest ideological-religious system - is a form of escape. Indeed, argues Tuan, it may well be the defining feature of humans, as a species, that we have this capacity to imagine and implement transformative projects; that we can turn the world to our will (or try to), rather than remaining the victim of Nature or of our own natures. "Escape" or "the imagination" is value-neutral, argues Tuan, as he explores the methods by which we attempt to escape from animality, and how it can lead us into both the grotesque and the sublime. What's incredibly satisfying about this book is that Tuan approaches his topic not from the position of philosopher or psychologist, but from the perspective of "human geography" which, in practice, becomes a helpful blend of sociology and anthropology grounded in history and science, but with enough gaps to allow for fruitful speculation. My only complaint is that the sheer breadth of Yi-Fu Tuan's knowledge leaves you feeling slightly dissatisfied, as if this book is only scratching the surface of an immense topic - which, of course, it necessarily is. So I suppose my dissatisfaction is only with myself. Thankfully, Tuan provides detailed notes and an excellent bibliography to point the way forward.
