Language, is only a tiny facet of
communication within nature, but even still words (sounds) and
gesture (sign language) are certainly not limited to humans. As far
as I know apes, other mammals and birds use sounds and movements to
communicate.
The mind is a wondrous and powerful
tool, yet its tenacity towards complexity, imagination and
story-telling, often seems to place us in our own little bubble
feeling as if we are cut-off from nature. Most of nature is not
cursed by such a 'bubble' and is more open or one with the rest of
life and so communicates in ways we know not of.
This is a great opportunity to help
open your dear son's mind by investigating with him into the many
ways that we are discovering how nature communicates (something that
could become a life's work with the end result probably offering far
more questions than answers).
An open and curious mind is not an
environment in which JW BS can easily thrive.
On another note, the speakers arrogance
that gives rise to him trying so hard to separate himself from the rest of nature, is in
my mind not far removed form the mind-set that allowed people to
slaughter the native Americans as “Godless savages”. I find it
deeply repugnant. We have infinitly more in-common with each-other
and nature than not. If we spent our energies discovering what
unites us and universe, then there would be no wars. But then Jehovah
never stood for that did he. He was a divider and destroyer, not a
uniter. How I ever actually believed in such a terrible creature, is
beyond me.
