These are excerpts and elaborations from my book "The Nature of Consciousness"
The Cognition-consciousness Problem The distinction between mind
and body was clear in Descartes' times, but it is getting less obvious by the day as the physical and
psychological sciences shed light on "mental" processes. Several of these processes are not exclusive
of the mind (let alone of the human mind), but quite pervasive in nature.
Remembering, learning, communicating are, to some extent, present in all forms
of life. Since Descartes, the dilemma
has been how do body and mind communicate.
But, today, there is no mystery in how, say, learning communicates with
the body: learning is a brain process that alters brain configurations in such
a way that a different behavior will occur. Today, we know that
"body" extends to the brain, and brain is responsible for many
phenomena that we consider mind and that are no more mysterious than the
movement of a hand. Therefore, within the Cartesian dichotomy, "body"
must be enlarged to encompass brain processes and "mind" must be
restricted to conscious experience. Otherwise, most of the mystery is not a
mystery at all: the way "mind" remembers or learns is no more
mysterious than the way a muscle gets stronger or weaker. What is mysterious is
that "remembering" and "learning" are sometimes associated
with conscious experience. That is the real puzzle: how does a brain process of
remembering (that is ultimately an electrochemical process of neurons
triggering each other) communicate with our conscious life of feelings and
emotions that seems to be located in a completely different dimension? As David Chalmers pointed out, the paradox to be
explained is not that body and mind communicate but that cognition and
consciousness communicate. Back to the beginning of the chapter "Mind and Matter" | Back to the index of all chapters |
