However, it does not rule out the possibility that "feeling" will turn
out to be something in addition to the vigorous reaction. The answers to
such questions, however, await a future time when we finally understand
how the human mind works.
What I find interesting is how extremely solid people's beliefs are
about what is conscious and what is not, even though they cannot
formulate any sort of rule for classification.
It almost seems you are more certain the less evidence you have.
It may have to do with emotional attachment. I particularly like
rabbits, turtles, fish and frogs and thus tend to presume they have
consciousness. Other people strongly dislike reptiles, especially
snakes, and so presume them unconscious.
As a child I played with snakes, bees, worms, earwigs, beetles, ants
salamanders, frogs, fish, rotifers, paramecia... I watched them try
to escape. I watched their intent activities. Presumably I made my
assumptions they were all conscious back then. There were all
certainly BUSY doing something. They all appeared to have intent.
I puzzle often over just what this inner experience is made of. It
seem so unlike anything else in the universe. Perhaps consciousness
is something fundamental like time or space. What we need to do is
stop asking WHAT it is and start asking "How can we measure it?" "How
can we classify it?"
There is agreement that bigger brains (e.g. more neurons) implies
greater likelihood of consciousness, based mainly on the observation
that one's self is conscious, and one has a large brain. So one
possible logical assumption would be consciousness would be
proportional to brainsize/neural system size. On the other hand,
human brains go TOTALLY unconscious when brain activity drops too low,
and POP BACK into full consciousness when it hits a certain threshold.
This hints you need a certain minimum amount of brain activity to
create a consciousness. Then on the other hand, unconscious humans are
unresponsive. The animals are are curious about are quite responsive.
Religion has taught us falsely that we are special. So I figure it
safest to add a little anti-special bias into my own attitudes about
mankind. Chances are we will find we are more like other species than
we now believe.
