Hello all,
The Hard Problem of Consciousness
https://en.wikipedia.org/wiki/Hard_problem_of_consciousness
is definitely a hoary old chestnut for the R&P forums and I feel it is a case of special pleading. Among many other fallacies IE the Loose Problem of Definition.
People don't argue about the Hard Problem of Digestion, although the functions of teh liver and metabolism are about as understood as neuroscience.
People don't argue about the Hard Problem of...
- Earthquakes
- Volcanic Eruption
Obviously the problem of definition, and its corollary, the fallacy of equivocation, make all these discussions difficult.
As I consider it, if a tiny
stimulating electrode inserted in the brain can generate conscious content (an experience) by driving activity in an interconnected circuit of neurons then what is left to explain? The activity in the circuit IS the experience. Considered in this way the "hard problem" is reduced to a complex but not impossible problem of neuroscience, that is, what kind of activity in which circuits is which conscious content? In addition the problem of "consciousness" as a separate entity from brain activity also disappears.
I confess to not having read Chalmers, or Dennette on the topic.
I have read and considered this paper by
Bjorn Merker. It has a lot to say about what "consciousness" is, and how and why the brain is designed to have it.
"It is the principal claim of the present target article that the vertebrate brain incorporates a solution to this decision problem, that it takes the general form of a neural analog reality simulation of the problem space of the tripartite interaction, and that the way this simulation is structured constitutes a conscious mode of function. It equips its bearers with veridical experience of an external world and their own tangible body maneuvering within it under the influence of feelings reflecting momentary needs, that is, what we normally call reality. To this end it features an analog (spatial) mobile “body” (action domain) embedded within a movement-stabilized analog (spatial) “world” (target domain) via a shared spatial coordinate system, subject to bias from motivational variables, and supplying a premotor output for the control of the full species-specific orienting reflex"
The tripartite interaction is the interaction between target selection, action selection and motivation (needs/drives).
"...It is not possible
to reap the benefits ... short of finding
some way of interfacing the three state spaces – each multidimensional
in its own right – within some common
coordinate space (decision framework) allowing their separate
momentary states to interact with and constrain one
another."
He is suggesting that the interaction of 1)needs and drives, 2) location of the individual in the world with relation to surrounding objects, and 3)the position of the body, all must be represented in a single overlapping multi-dimensional space in order to allow rapid and accurate targeting for the organism to survive. This, he suggests, is the evolutionary origin of "consciousness" (neural analog reality simulation).
Its quite an interesting read.
I can't make the link work... Its called Consciousness without a cortex, and there is a full pdf available through google scholar...
