where does consciousness begin ?

Well according to this science article it has it's start in quantum physics

Quote:

A decades-old and controversial theory suggesting that quantum effects in the brain could explain consciousness may hold more weight than scientists gave it credit for.

The nature of consciousness has long puzzled us. One idea, traditionally seen as far fetched, is that the unusual laws that govern the quantum world could be behind what allows us to experience consciousness, New Scientist reports.

Quote:

… Unfortunately for such attitudes, consciousness is not just an epiphenomenon, a strange concomitant of our neural activity that we project onto physical reality. On the contrary, all that we know, including all our science, is in our consciousness. It is part, not of the superstructure, but of the foundations. No consciousness, no science. Perhaps, indeed, no consciousness, no reality -- of which more later.

Though consciousness is the essential condition for all science, science cannot deal with it. That is not because it is an unassimilable element within science, but just the opposite: science is a highly digestible element within consciousness, which includes science as a limited territory within the much wider reality of whose existence we are conscious. Consciousness itself lies outside the parameters of space and time that would make it accessible to science, and that realization carries an enormous consequence: consciousness cannot be located. But more: it has no location. - George Wald

I "think" most of us have opinions about where it isn't. :Kaleun_Wink:

I think its indispensable to separate mind/consciousness from - in absence of a better term - spirit. The first has its basis in structured matter, without matter coming to according form, mind/consciousness cannot form and cannot prevail. They are a function of matter and structure. The latter - spirit - however is and must remain to be an object of speculation.

Agree there have been times in my life I suffered from what doctors would define as a ‘rectal cranial inversion’. And I tell you with all certainty consciousness is not up there. :haha:

Where does consciousness come from? Does your consciousness exist before you are born? If so, where is it?

Consciousness is a funtion of brain activity.

Automatted behaviour and reaction is instincts (which again get processed partially in the brain, partially directly in the peripheral neurons).

Whether there is a mind, or as I called it: spirit, without matter structured in a brain, is a metaphysical speculation - knowing for certain we do not anything, many however believe in claimed answers.

Atman and Anatman: Buddha said no individual Atman/ego (or mind) survives death, but there were the real, the non-ego (anatman) pointing to a quality that is bigger and beyond the individual existence. "Show me your true face that you had before you and you mother and father were born" is a famous koan in Zen.

In the end the miracle lies in that things, that all this even exist. Why do they? Why isn't there just nothing? All we perceive however is not what things, existence, cosmos really is like, because we perceive according to the individual design of the physical sensor used. We can conclude the sensor is what it is becasue it follows a physical need that dictates the form: but where did this proces start, and why? We do not deal with reality, but our imagination/interpretation of it. We deal with our own model - not with what the model is claimed to describe.

That my days have been a dream;
Yet if hope has flown away
In a night, or in a day,
In a vision, or in none,
Is it therefore the less gone?
All that we see or seem
Is but a dream within a dream.

I stand amid the roar
Of a surf-tormented shore,
And I hold within my hand
Grains of the golden sand —
How few! yet how they creep
Through my fingers to the deep,
While I weep — while I weep!
O God! Can I not grasp
Them with a tighter clasp?
O God! can I not save
One from the pitiless wave?
Is all that we see or seem
But a dream within a dream?

E.A. Poe

I remember an interesting thing that happened when my Niece was about ½-1 year old.

I was holding her and showed her the mirror-Look I said that's you.
My little sister replied..She hasn't developed her consciousness yet
When she said this I started to study my niece face expression when see looked at the mirror and I didn't see any changes.

My conclusion after having studied her with the mirror is:
It does not exclude that she does not have a consciousness
Even though she does not know what she see in the mirror.

Left mine at subsim door I figure with the folks around here it would get corrupt anyway

I found this science article in a Danish science magazine.

Quote:

When did humans become conscious?
When in human history did consciousness arise, asks a reader. We take a trip back in time to find the answer.

For millennia, philosophers and religionists have dictated that consciousness makes humans special. In other words, consciousness sets man apart from all other animals.

That has one of our readers wondering:

"So when in human history did consciousness emerge?" writes the reader in an email to 'Ask Science'.

We pick up the readers question and pass it on to Professor of Evolutionary Studies at Aarhus University Peter C. Kjærgaard. Maybe he can tell us when humans first realised they were human

Definition of biological consciousness

Before we can answer the Reader's question, however, we must first define what consciousness actually is.

In this context, philosophers have come up with many different definitions over the years:

Some of the more commonly used definitions are subjectivity and the capacity to experience or feel. So is 'the ability to be aware of something inside oneself'.

In an evolutionary context, however, we have to use a slightly different kind of definition, says Peter C. Kjærgaard.

"Consciousness is, in an evolutionary sense, a banal tool that helps us gain a better and more nuanced picture of reality and the world around us. Consciousness gives the individual the ability to look at himself, look inwards and see how other individuals react in certain situations. As such, consciousness is the ultimate tool of social man," he says of the biological definition of consciousness.

Cavemen had consciousness

If we look back at the history of human evolution, we can now make a few hints here and there in the search for the origins of consciousness.

40,000 years ago, cave men drew paintings in some caves in Spain. Did the cave dwellers have consciousness?

"In order to be able to make the paintings, it is necessary that 40,000 years ago the cavemen had consciousness. After all, it took an enhanced view of reality to depict it," says Peter C. Kjærgaard and continues:

"At the same time, it is interesting that new studies show that some of the cave paintings were probably made by Neanderthals and not Homo sapiens. So we can immediately conclude that consciousness is not unique to our species, but has also existed in other species."

Consciousness has existed for millions of years

Looking further back through the line of ancestors, several of them also show signs of consciousness in the form of cave paintings, social structures and the desire to use colours to decorate themselves.

Homo sapiens have consciousness, and apparently so did Neanderthals. This means that consciousness emerged at least 600 000 years ago.

Homo erectus also had consciousness. They used it to make the first trip of the human race out of Africa. Their emergence can be dated back 1.8 million years.

Homo habilis also had consciousness 2.3 million years ago, as did Australopithecus afarensis 3.9 million years ago.

"We so want consciousness to be something great and fine and very special to humans. But it just isn't. As our ancestors evolved, their brains grew, and so did their consciousness. It all happens in an interplay between diet, social complexity and climate. Our earlier ancestors certainly had consciousness too. We just have more of it today," says Peter C. Kjærgaard.

Monkeys have consciousness too

So it seems that all human ancestors - since our lineage split from that of chimpanzees - have had consciousness in one form or another.

The question then is: Did the chimps have it too?

Scientists have certainly already investigated that for us.

"There have been experiments with bonobos and chimpanzees to show whether monkeys have consciousness too. The experiments show that monkeys can also learn, plan, receive knowledge and pass on culture. In other words, they also have consciousness," says Peter C. Kjærgaard.

All mammals have consciousness

Consciousness, then, is not exclusive to humans or to the human species in general. Animals have consciousness too.

Nobel Prize-winning neuropsychologist John Carew Eccles, who was particularly interested in the origins of consciousness, suggested that consciousness dates back as much as 200 million years to the time when the first mammals evolved from reptiles.
Peter C. Kjærgaard agrees:

"John Carew Eccles concluded that consciousness is nothing more than a tool for better adaptation to the environment. I agree. Consciousness lies solely in the organisation of the brain. This changed when reptiles became mammals 200 million years ago. With the change in the brain and the emergence of consciousness, mammals became better able to orient themselves to their environment and thus better able to survive," he says.

Humans have more consciousness than other animals

We can thus conclude that the answer to Louise's question must be that consciousness is by no means unique to humans or even to the human species either. It emerged 200 million years ago, while dinosaurs were still roaming the Earth.

All mammals have consciousness. Humans just have more of it, as it has been a clear evolutionary advantage in our social group structure.

"Moreover, consciousness is inextricably linked to brain size and complexity. Here, humans are unmatched by other animals and also by our earlier ancestors. We can see that the brain has grown and become more complex over millions of years. At the same time, there is more of the consciousness that has always been there, after all," says Peter C. Kjærgaard.

We hope the reader finds the answer useful, and thank you for the question with one of our coveted 'Ask Science' T-shirts.

We also thank Peter C. Kjærgaard for making us more aware of human consciousness.

And what about marine mammals? They aslo have large brains but don't have hands to make tools.

More and more animals are beign given the status of being "sentient" beings, latest example: squids. While it was long assumed that fishes do not feel pain, this is no longer a view accepted by every biologist. And our old understanding of bird'S intelligence has seen a revolution in past 30 years or so, and led to a remapping of our understanding of the bird brain. Theiur density in neurosn is much higher than that of apes, mammals, our brains, and so even some bird species' tinier brain mass can show up with intelligence performances and social competences as we usually only see in Bonobos, chimps, humans, etc. - think of parrot species, raven-species, kiwis...

And human babies, from around 18 months on they can recongise themselve sin mirrors, we know that form the Rouge-test: a coloured dot is placed on the face of the baby and then it gets a mirror, when it looks into the mirror, it uses its hand to remove the spot in its real face, not in the relfected image. First primitive differentiations between "me" and "the other" are formed already before that age. Verbal competence to refer to oneself is formed at the end of the second year. Autobiographic self-understanding and self-related memory-reflection forms up from 3rd and 4th year on.

Its obvious to me that there is a clear link between these mental performances, and compexity of neural structures. The brain developes, so do its performances. No brain: no performance.

I have given up to say or think in terms of "its just an animal". The word "just" in this sentence often is not justified, and undeservedly derogatory.

Treat living beings with respect, and kindness. Thats a general ethics. That includes hunting and lifestock farming. I made the experience often that the kindness I gave to an animal feels as if I gave it to myself, independent from the answer of the animal.

Or take the sqiurrels in my garden. They do not seek my closeness, they avpoid me, but I see them on video making heavy use of the water and the nut bar and all that I do to help them over the year and especially winter. I feel good when I see them using all that, and I enjoy that they are in good health, and well-fed, and strong in ohysicla appearance. That is a satisfaciton I gain without me needing to "own" the other being.

How can you keep your love? Let it free to go as it likes. No ownership involved, nor needed.
