The Hearth-to-Furnace Transition
Borgmann's paradigmatic example: the replacement of the wood-burning hearth by the central heating system, which delivers the same commodity — warmth — while eliminating every demand the hearth placed on skill, attention, and shared presence.
The hearth-to-furnace transition is the founding illustration of the
device paradigm. Both deliver warmth. The hearth demands chopping, fire-building,
tending, and the gathering of the household around a directional, crackling, smoky source that organizes the rhythm of an evening. The furnace delivers warmth silently, invisibly, and uniformly through ducts behind drywall, operated by a thermostat that demands no understanding of combustion. The commodity is preserved. The machinery is concealed. The user is
disburdened of everything the hearth required. Borgmann's claim, developed across four decades, is that the loss of those demands is a real event with real consequences for what a household is, and that a
culture that makes this transition in every domain simultaneously has remade itself in ways it cannot perceive.
