Fire as a Medium
All cultures have rituals with fire. On the surface level, we think about fire as a communicative medium.
Fire can be seen as a transformer of things, changing natural things into those made specific to humans.
Fire doesn't necessarily contain a message most of the time.
Pharmakons
It led to the self-domestication of humans, where we became more dependent on a stable environment, but became less environmentally aware and dependent on nature's rhythmic cycles.
Material and Immaterial
Fire is used as a symbol, such as for desire, destruction, and time.
Management Systems
For instance, we need humans to control fire outbreaks. In order to have the affordance of fire, we need new kinds of media and developments of technology to control fire.
