We are in the midst of an intensifying search for belonging, one that makes the idea of home as important to politics as the idea of class or rights – especially now, when so many people feel displaced, both literally and figuratively, by life in innovation-driven, high-tech, networked capitalism. The contest over where home is and who is entitled to live there, is – in the form of the current apparent crisis over migration – driving global political debate. Few philosophers have thought much about the idea of home. The only one of note is controversial: Martin Heidegger. This essay explores what we could learn from his analysis of why home matters so much to us.
