The Swiss psychologist Carl Jung was fascinated by this idea of humans communing with the natural world. Following a lifetime of research on the subject he wrote:

"As scientific understanding has grown, so our world has become dehumanized. Man feels himself isolated in the cosmos because he is no longer involved in nature and has lost his emotional unconscious identity with natural phenomena...no voices now speak to man from stones, plants and animals, nor does he speak to them believing they can hear. His contact with nature has gone, and with it the profound emotional energy that this
connection supplied...primitive man was much more governed by his instincts than are his "rational" modern descendants, who have learned to "control" themselves. In this civilizing process, we have increasingly divided our consciousness from the deeper instinctive strata of the human psyche, and even ultimately from the somatic (bodily felt and known) basis of psychic phenomenon. Fortunately we have not lost these basic instinctive strata; they remain part of the unconscious, even though they may express themselves only in the form of dream images."
