AWARENESS
before we go ahead and take a closer
look at why things are thinks are thinkgs, lets take a big step
back:
"early mammals were creatures that had been driven to a
nocturnal lifestyle, because the competition for food with the dinosaurs
and other reptiles was too intense. without the sun on their backs to
warm their blood, to stir their metabolism, these diminutive animals had
been compelled to evolve their own thermostats. they had become
warmblooded.
but that innovation brought with it a new problem.
to fuel a built-in temperature-control system, you have to eat often and
well. some of these nascent mammals were no bigger than a mouse, so they
could not gorge themselves on a single kill. they lost body heat fast
and burnt calories at a prodigious rate. as a result, they had to feed,
or be on the lookout for food, continuously while they were awake. at
best, fruit and other plant matter could have served them as hors d'
oeuvres. for the main course they had to have a regular intake of animal
protein, like insects, and plenty of them. they had to catch these
skittery morsels in the dark, so that superb night vision, as well as a
keen nose and ears, was essential.
and what is more, they had to
pursue and hunt their prey, actively, relentlessly. of all the factors,
this was the most decisive, because it demanded the fabrication of a
more detailed, dynamic mental model of the creature's surroundings, a
more potent projection of reality.
to survive, the first mammals
had to develop a curiosity about their environment, such as had never
before existed on earth. they had to peer behind corners, under leaves,
everywhere, with intense interest, all their waking time, because if
they failed to eat each hour they would probably die. only the best
searchers, those with the most inquisitive brains, would live to
reproduce. it meant, a complete departure from the old stolid, reptilian
approach. and it meant, concomitantly, a massive expansion of neural
circuitry in the brain. billions of neurons were needed to integrate the
flood of new visual, auditory, olfactory, and tactile data, to unite
these senses as they had never been properly integrated in the reptiles,
and to transform the resulting complex inner model smoothly, millisecond
by millisecond.
to occupy their niche, they had to be able to
fashion a detailed and unified, multisensorial picture of the world
around them. the data flowing in from the senses had to be merged
internally, and the only way to do that was for the brain to develop a
coding system. this involved tagging the incoming data from each sense
organ, so that corresponding items of data (giving, say the exact
distance and direction of an insect in the dark) could be matched up.
that is an awesome computational problem. and it is one that had to be
solved over and over again with each passing moment.
once this
mechanism was in place, the association areas of the mammalian brain
properly wired up and the sense fully intergrated, there was somethinkg
new on this planet. it was the concept of an object, an
object in space and time. and though the mental counterparts of the
objects held in the brains of the dawn mammals must still have been
vague and only dimly experienced, yet they represented an enormous
advance.
furthermore, to complement and make full sense of the
improved internal reality, there had to be an enhanced participation in
that reality. the animal had to act inquisitively in order to find
enough food to survive, and the simplest way for that to happen was for
it to feel inquisitive. instead of responding passively to isolated
stimuli in the way reptilians do, the early mammals became increasingly
involved with the mental objects of their experience. they weighed up
alternatives, tried out different possibilities (especially through play
when young), experienced an inner drive toward some elusive goal. they
felt conscious."
