Non-Human Consciousness: Exploring First-Person Experience

In summary, the conversation discusses the relationship between human and animal consciousness, and how it relates to evolution and the mind/body debate in philosophy. The participants suggest that emotions and feelings are markers of old evolutionary imperatives and that animals likely have first-person experiences similar to primitive human feelings. They also discuss the challenge of accounting for first-person experience in natural systems beyond just the human case. The topic of animal consciousness is brought up, with some participants arguing that we can understand it by looking at the neural correlates of human experiences, while others suggest it may be difficult to truly understand without first-person accounts.

I wanted to see if any of you had thoughts on the following: our feelings and emotions appear to be markers of old evolutionary imperatives (fight, flee, eat, etc.). The mind/body debate in philosophy got started before evolutionary theory was accepted (Descartes evidently thought animals were automata). Given we now better understand our close relationship with our non-verbal animal cousins, I am persuaded that animals have first-person experiences of a sort, probably much like our more primitive feelings.

If so, then the “hard problem” can be seen as the challenge of accounting for first-person experience in natural systems more broadly than just the human case; the issue can be seen as distinct from others relating to human intelligence and language.

Human intelligence and language also find analogs in non-human animals, so I'm not sure there's any more of a split between the study of human and non-human consciousness than there is a split between the study of human and non-human intelligence and language. They are all connected evolutionarily.

You're right, of course. Every attribute we have is connected due to our shared lineage. However, I think feelings are first person markers of more primitive adaptations and are likely to be much more closely aligned with animals, compared to language ability for instance.

It is very much a feature of the current mind/body debate to avoid "parochialism" --
the idea that mind/consciousness is purely human. This intorduce the problem of
relating mental types to physical types without beign overly restirictive of the kind
of brain/computer that implements mental states, and accounts for the popularity of functionalism (which , according to its critics, is not parochial enough).

Thanks. what's interesting to me about animal consciousness, though, is that presumably the cognitive processes are simpler and perhaps less interesting to the computational wing of the functionalist school, and yet (I speculate) the raw experiential qualities of fear, pain, hunger could be very robust.

But having no first person accounts, how would we ever know? It seems to me much of the animal consciousness movement just amounts to declaring them conscious because that seems a humane thing to do.

Animal problem solving does not prove consciousness. Computers solve problems too, including problems they were not "built to solve".

We know about other human minds by analogy with our own. To inform us about animal minds, I think we would proceed by looking at the neural correlates of certain human experiences, and seeing which have close analogues in the neural structures of animals and which don't. I've read some accounts of work in this area, and will come back and post examples when I find them. It was my impression that higher powers of cognition and language are correlated relatively more with our highly developed cortex, whereas emotions and pain are relatively more situated in sub-cortical areas which have changed less in our descent from some common ancestors. But I admit I'm talking without a good knowledge base here - if anyone else can either back this up or refute it, let me know.

It's true that most of the so-called "higher powers of cognition" take place primarily in the neocortex. However, I think selfAdjoint has a point. To wonder about whether another species of animal is conscious or not is the same as wondering whether another human is conscious or not. It is an attempt to establish whether that being belongs within your "group". Indeed, you'll notice that most of the animals we are more reluctant to harm or kill (the cuter ones :wink:) are those that have features (specifically, facial features) that resemble our own to some degree or other. We are simply worried about harming something that might conceivably respond the same way a member of our group would.

To think evolutionarily, isn't there a benefit in recoiling at the thought of harming "one of your own" (at least, for an inherently social animal)?

Yes. It works well within the contex of Paul Maclean's "Triune Brain". Know about it? We have 3 brains: the reptilian complex, limbic system, and of course, our crowning achievement, the neocortex. Emotions emerge from our mamalian vestige, the limbic system, as a survival strategy for protecting the young.

Right. From what I've read, the evolutionary grounding of impulses such as cooperation and altruism does indeed start with our original stance toward kin which was then extended to encompass larger social groups. It is natural that we feel less and less of a positive moral imperative in our behavior toward more and more distant species down the ancestral line. Going back to consciousness, it seems logical that the similarity of first-person experience will generally correlate with distance on the family tree as well. However, breaking things down one level further, my particular point is that some of the most robust and compelling first-person experiences (emotion, pain) may be ones which have changesd relatively less as we diverged from some of our cousins.

Thanks for the reminder about MacLean. It is what was in my mind but I couldn't place it.

Hi Steve,
If all we have is a first person experience (1PE) which we consider consciousness, and from it we infer others' 1PE, I have no doubt that my dog is as conscious as I am. I've been observing his behaviour for many hours for many years and can't think otherwise. However, I think I doubt that he is conscious of being conscious.
Don't know if this is of any help.

Thanks antfm. It is often pointed out that we must be cautious about the possibility that we are inappropriately "anthropomorphizing" when we infer things from our observations of animal behavior. Finding the neural correlates of consciousness and then seeing which structures are common with animals will put this on firmer footing. With that said, I tend to agree with you in thinking that the first person experience of higher mammals has much in common with our own conscious experience, although introspective or reflective self-consciousness may be unique to us.

I understand the objection, Steve. That is a problem that we are always going to encounter. Since if 1PE is our only basic ground we have always to make inferences, and this should be so even to assign consciousness to anybody different from oneself (at least until neural correlates were clearly proved to mean consciousness).
When I say I've no doubt that my dog is conscious, I know I'm just exposing a personal belief or whatever. But it's not but a raw way to say that I infer that he experiences, that he enjoys and he suffers (appart from all human connotations of these words), so he has some kind of consciousness. But considering that just as an hypothesis (and I hope not a far fetched one), I think it might be helpful to enlarge the field of research in consciousness,
and consider it as a more general phenomenon in nature, one spreading from simpler to more complex forms, and related also to the evolution of living beings, which I thought was in the origin of your thread.

Two more points: if you search the web for "pain in fishes" for instance, you'll find some research articles about animal consciousness (sorry I haven't got the links).
Second, I am sure that my dog has dreams. But, dogs appart, just from human dreams I think we should also try to understand consciousness not just as the waking state experience.

Sorry if this sounds too folky philosophy. I'll try to improve.

Thanks for mentioning this -- that was one my intended points, which I sort of got away from.

I think most would agree that all forms of life have consciousness with varying degrees of self awareness. Looking at the Earth from a holistic point of view, the Earth is a big ball of rock that has come alive and started thinking. With this in mind one has to ask if inanimate objects such as rocks and water have consciousness. It is not such an odd idea that is very old and has been picked up by the new age movement.

FYI, as a follow-up, I wanted to mention that the journal Consciousess and Cognition has a new special issue on the Neurobiology of Animal Consciousness. Just what the doctor ordered! I have just read the introductory article by Bernard Baars so far. Here's the abstract:

In humans, conscious perception and cognition depends upon the thalamocortical (T-C) complex, which supports perception, explicit cognition, memory, language, planning, and strategic control. When parts of the T-C system are damaged or stimulated, corresponding effects are found on conscious contents and state, as assessed by reliable reports. In contrast, large regions like cerebellum and basal ganglia can be damaged without affecting conscious cognition directly. Functional brain recordings also show robust activity differences in cortex between experimentally matched conscious and unconscious events. This basic anatomy and physiology is highly conserved in mammals and perhaps ancestral reptiles. While language is absent in other species, homologies in perception, memory, and motor cortex suggest that consciousness of one kind or another may be biologically fundamental and phylogenetically ancient. In humans we infer subjective experiences from behavioral and brain evidence. This evidence is quite similar in other mammals and perhaps some non-mammalian species. On the weight of the biological evidence, therefore, subjectivity may be conserved in species with human-like brains and behavior.

The evidence for human-like subjective experience seems compelling for mammals; less so for non-mammals, but less research has been done on those. Cheers, - Steve

Thanks for the information, Steve. Very interesting link.
I keep thinking that approaches to consciousness in animals could give us some better understanding of the phenomenon of consciousness in general. But, consciousness is, still, a term too loaded with human connotations. We seem to have some difficulties to isolate the notion of subjective experience from the accompanying features of it in the human case (those that you, for instance, have characterized as reflective consciousness, etc).
If, us, human being, are basically that property of subjective experience, though highly evolved or entangled with cognitive faculties, it is difficult to think that, being that property somehow 'available' in nature, it is not present in other animals.
But, up to where could we track back that property of subjective experience in animals? What kind of brains or nervous systems can hold it? Where does it just seem to dissolve in pure action-reaction with environment?
 

1. What is non-human consciousness?

Non-human consciousness refers to the awareness and subjective experience of beings that are not classified as humans, such as animals, plants, or even artificial intelligence. It is the ability to perceive and process information, have emotions, and make decisions based on internal states and external stimuli.

2. Can non-human beings experience consciousness?

There is ongoing debate and research in the scientific community about whether non-human beings are capable of experiencing consciousness. Some studies suggest that certain animals, such as primates, dolphins, and birds, show signs of self-awareness and have complex cognitive abilities, indicating some level of consciousness. However, it is difficult to definitively determine the subjective experience of non-human beings.

3. How do scientists study non-human consciousness?

Scientists use various methods to study non-human consciousness, including behavioral observations, brain imaging techniques, and comparative studies with humans. Researchers also look at the presence of certain cognitive abilities, such as self-awareness, problem-solving skills, and emotional responses, to understand the level of consciousness in non-human beings.

4. What are the implications of non-human consciousness?

The existence of non-human consciousness raises ethical and moral considerations, particularly in regards to the treatment and use of animals for scientific research and other purposes. It also challenges our understanding of consciousness and raises questions about the nature of subjective experience and the potential for consciousness in non-biological entities.

5. How does studying non-human consciousness contribute to our understanding of consciousness?

By studying non-human consciousness, scientists hope to gain a better understanding of the mechanisms and evolution of consciousness. It allows for a broader perspective on the range of conscious experiences and can provide insights into the neural processes and cognitive abilities that underlie consciousness in all beings.
