@jeeprs,
This is in process of responding towards posts related to my opening post answer (my
#116) towards jeepers' number
98.
I appreciate and am pleased, salima, meri baheen, with your politeness and word choice (
#132), and also can understand how confusion can occur when new word senses are being used. I will do my best to explain.
As I take it to be, paulhanke, you are good with detail, and that is one thing that I can always appreciate. Also, along with the detail, being able to keep it focused while yet being able to pull back from that--all the while never forgetting the detail--and see the big picture, is a good trait to have, indeed. I am not perfect with that, but make an effort.
Now, I shouldn't try to say any more than what I can see, or formulate from what I see, so I'm not sure, however, if it
is the case that you responded (your
#131) to my #130 (pg 13) as you read (since the flow and content appear to be such), rather than having read the whole, then responding after that, it could be that
that may possibly have led to some confusion as well. Please do allow me, here, to point out what I mean, and explain my position.
First of all the word usage. Without going into English grammer, suffice it to say that quasi forms are not so uncommon to English at all--which is why, for example, we can enjoy partying, or have a ball, or (at least when I was in college) xerox a form. For this reason, it would be impeding to overly emphasize the grammatical form, if by doing so the sense of the usage of the word becomes muddled.
The word
conscious, actually, is already considered a noun as well as an adjective, but has (as far as I have seen) only a single sense--
the 'entity' of the state of consciousness. Chamber's 21st Century Dictionary, Revised Ed. (1999) gives us the following entry for the noun [most dictionaries that give the noun entry (some don't) simply refer to one entry under the adjective list] :
[indent]
"n. the part of the human mind which is responsible for such awareness, and is concerned with percieving and reacting to external objects and events."[/indent]
This is why I actually didn't need to identify my noun usage of the word
conscious, yet did so anyway, so as to help bear out that I am using it in a new, and different
sense from the given sense of the word as a noun, as well as that my adjective usage, depending on
context is from the sense of the noun as I use it. But just what
is that sense, and just how is that your concern can be relieved?
I hope to make it clearer, so will first ask that a review of paragraphs 3~6 from my
# 116, and ponder it carefully as it works in here. We can go back to pre-Cambrian time and find life forms in the realm of bacteria and archaea organisms--especially the anaerobic ones--and while these are organisims which are on the 'tree of life,' there is no need to consider that they had anything like ganglion. During this period called the
Phanerozoic eon (from about 540 million years ago, to present) there have been a number of extinction crisis, with varying degrees of extinction intensity--
the most famous being that at the end of the Paleozoic era(Permian/Triassic boundry)
which is thought to have wiped out somewhere in the neighborhood of 80%~85% of living species.
We can stand here, on this point which is the present age, and get a pretty good sense of just how many ganglion/brain based life forms (species) there are, and have been. We have learned, and are learning, of and about this variety and procession of ganglion/brain build that has progressed up to the point of H. sapien. Therefore, whenever we talk about brain, we must do so on the data and understanding of the
entire playing field. What
is it that is different in the ganglion/brain cells, as opposed to bone, muscle, skin, or hair cells? (
* from here on out, I'm just gonna use the word 'brain' for the whole type)
One thing that we can see, without having to do too much studying or searching, is that the 'major-player' brain cells signal to each other in groups, or maps, and that they have, over the course of evolutionary development, come to form groups, or structures, to perform rather specific things. It is specifically this trait which distinguishes (especially) the neuron from other cell types. What this entails, in turn, is that we will have degree of activity tied in with cell count--
the fruitfly's brain is on a much lower activity scale (level) than that of a dolphin.
Now, we can see that while each species has a normal brain build for that same, particular species, we can also determine that there is a general continuum of species similarity--
a line from one extreme, say, the H. sapien, and the other extreme, say, an extinct amphibian of some sorts. Also, as Homo genus slowly 'branched out' on its own, we can be pretty sure that brain build, and thus activity scales were not always the same--
and yet all these creatures were of course breathing, moving, making noise, thinking, and planning (to whatever degree).
We must then add to that, the particular instances of a newly prenatally formed brain that builds according to genetical 'blueprint,' across all species, and that same brain's overall activity level as it matures to the fullest--for each specific 'blueprint.' Then, we'll have to consider all differences of brain build determined activity levels; and stepping back, and looking at the big picture, we have an organ which maintains various degrees, or levels, or involvement, of activity for which there is no word.
'Consciousness,' from which one sense of the word
conscious (as an adjective) comes, has a rather specific working definition which we should adhere to. Even if one would stubbornly tend
not to agree that all brains are sentient organs (used in the sense of mere awareness), that same one could in no way deny that all brains are
consious--
in the sense of having degrees, or levels, or involvement of activity. In this way, there is neither error nor awkwardness in saying that a particular brain being investigated will have a state of conscious, but not a state of consciousness.① Also, by using conscious in this sense, we can avoid the obsolete negative--
but it is most important to keep things in context (as is true with many words, clauses, and phrases !!), and to understand sense from the context that it is in.
A brain is a conscious organ, the spleen not so. A brain at a resting state is of a certain degree of activity--conscious--which is less involved than that degree of that same brain's being in a fight-or-flight state, but both states are those of having conscious (and this in an uncountable noun, so no article is needed). The state of a brain in slow wave sleep is quite different from the state that it would be in when fully awake and alert, yet both states, regardless of degree of activity, are states of conscious.
I will admit, paulhanke, that it was going a bit out of the way to say that each neuron has a state of conscious---although in this sense, it is true. We have to keep in mind also that in the same way that the specific neurons in the motor cortext will process for that function (and not, for example, visual input, auditory, etc.), and the specific neurons of the substantia nigra will process for dopamine to the striatum, neurons are 'designated.' Also, since when we talk of brain, or the brain, we automatically assume the understanding that we are talking about the living, active neurons and their respective clusters, gryi, and so on, we don't really need to make mention of that fact.
The term
conscious, therefore, is a (quasi-)noun, and as a noun, in the sense of being a condition, or state, of a biological entity which is generally called a brain (made up of, largely, brain [as the uncountable noun, as in tissue]), it best describes the fact of activity of the entire span of brain builds over evolutionary time, individual species builds or traits, and the particular build and/or state of the individual creature's specific brain, as well as brain as a tissue type. While the sense being employed is new, language is a fluid thing, and new words and senses both gradually form decay over time, all the time. In that the word's function best fits what is known today, as opposed to the lack of understanding of several hundred years ago, I encourage all to take careful note of, not be afraid to use it--
but am not demanding it. Please do take care with context as I use the word so as to distinguish between noun and adjective, and senses. Thank you. KJ
This
IS long, I know, and am guilty. I just felt I had to lay it out more fully to better ascertain proper take. I apologize.
① Of course here, we could use that other definition of sentient, "1. a sentient state or quality; capacity for feeling or perceiving; consciousness" (Webster's New World Dictionary, College Edition (1976)) and then get into some kind of loop argument...only brains with consciousness have consciousness . . . ? But the second definition is actually about the same as saying all brains have states of conscious, because it is, "2. mere awareness or sensation that does not involve thought or perception."
