Fire, Plasma, Technology

Plasma has replaced Fire as one of the four fundamental States of Matter, previously known as Elements.  Now, since Plasma exists in abundance everywhere in the universe except on the surface of the Earth, where the most familiar manifestation of it is lightning, Franklin's harnessing of Electricity via bottling lightning is effectively a bringing Plasma down to Earth, for human use.  This action is thus comparable to the mythological bringing of Fire to human use from the gods, by Prometheus.  The notable aspect of the contrast between Fire and Plasma in this case is the punishment of Prometheus, thereby signifying that human Technology no longer has the status of crime or sin.
