You went to bed but couldn't sleep, Carol is
sleeping soundly. So, you are up sitting in the living room chair thinking
about the day. You and Carol talked most of the way up to Kim and Paul's,
stopped at Panera on Rt. 23 not far from the Powell Road intersection north of
Worthington. Snowing began and when you finished lunch the roads were lightly
covered. Not long after you arrived Carol and Kim drove to Polaris for
shopping. You took a nap as did Paul, the boys were outside playing in the
snow. Early supper at Olive Garden then a relaxing evening. Not much to be
thinking about boy? - Amorella

did find this commentary below on Quora this afternoon. It's a couple years old
but interesting.

Is consciousness
a step change or a continuous spectrum?

The emerging view among
neuroscientists who study consciousness is that consciousness is a spectrum,
both within a given organism and across species.
Human consciousness for a
given human can range from dreamless sleep (unconscious) to awake and alert
(conscious). In between these extremes are various semi-conscious states such
as mild anesthesia (conscious sedation), or the feeling you have when you just
wake up, called the hypnogogic state. Dreaming and especially lucid dreaming is
a state that is conscious in some ways and not in others. Lastly, someone with
extreme dementia is somewhat conscious, but not in a way we would really
recognize, with limited awareness and understanding of their environment.
At the species level, it
is starting to be accepted that animals are conscious to varying degrees.
Mammals, for example, have the same extremes of dreamless sleep to the fully
awake alert state. If sleep is unconscious, then what is awake? At the very
least, this is a conscious state in the medical sense, and animals can be
sedated with general anesthesia just as humans can.
But how conscious is an
animal?
If consciousness is defined as "perceptual awareness"
-- some understanding of the environment that includes short-term memory and an
ability to comprehend the environment and make decisions to act -- then monkeys
are fairly conscious. Dolphins and whales are regarded as conscious in some
sort of "intelligent" sense. Dogs seem conscious but less so. Birds
such as parrots even less. And lately octopuses are being regarded as
exhibiting primitive consciousness in an invertebrate with a distributed
nervous system and without a typical brain. Insects are sufficiently
mechanistic without much ability to learn, so they are probably not conscious
at all. Honeybees are able to memorize pathways to flowers and communicate the path
with a dance that is recognized by other honeybees, so perhaps they push the
boundary at the lower edge somewhat.

2347 hours. I
underlined the sentence that intrigues me the most -- octopuses exhibiting a
primitive consciousness without a typical brain. My question
is: how is this so? I will sleep on it and do
further research in the morning. Why? I am not sure.
