(Critical Junkyard) 'Paleolithic Consciousness'

In Chapter 4 (Wilderness) of Ecocriticism, Garrard quotes John Muir's term 'Paleolithic consciousness' referring to, in my understanding, a state of environmental consciousness akin to that held by humans in the Paleolithic Age. This means that humans would have a renewed sense of the sacredness of all beings and the interconnectedness of the universe.
