Do you think any animals have consciousness?

Sure. If you believe in evolution, then you accept that humans are essentially animals with highly evolved brains. The interesting question really is how animal consciousness compares to human consciousness; do some animals have the capacity for abstract thought? Empathy? Self-reflection? Creativity? A cat knows that the Sun provides warmth and light and it likes to sleep on the floor in a beam of Sunlight. But does that cat ever try to rationalize what the Sun is and how it is different from the Moon? Who can tell? :lol:

Why is it an Achilles heel, then? :)

The answers will not be identical like people are not identical, but given there at fields with shared understandings and expertise to be had, I would not say the answers being entirely subjective and bespoke to the individual is fully true. There are harmonies to be had. Just that there is a hell of a lot of qualitative to be had in this universe, which is beyond the scope of natural sciences.

Philosophy is good for giving food for thought, challenge views and ethics, initiate debate and ask questions. It sucks at providing answers though, because debate is mostly carried out between subjective viewpoints. You can say it like this; philosophy provides no objective truths or objective insight. Everything is argumentative and subjective. Science is all about objective truths and facts. It doesn't matter how well you can argue that 'x is fact' - if experiment doesn't comply with the argument, then the argument is wrong. You then make a new argument/theory and test it via experiment again aka the scientific method.

Just out today: rats have an imagination/the capacity to navigate a mental map of the world

The rats could sustain a hippocampal representation of a remote location for tens of seconds, reminiscent of human imagination or mental time travel.​

Spoiler More details :
Researchers employed a brain-machine interface in which electrodes were surgically implanted into the rats’ brains. The rats were then placed on a treadmill ball within a 360-degree immersive virtual reality (VR) arena, and presented with an on-screen goal to run towards.

As the rats moved, and the treadmill ball turned, the animal’s apparent location within the VR environment updated on screen – as if the rat was running through a real environment. When the rats reached the goal, they received a treat and the goal was moved within the VR environment. The process was then repeated.

During this initial phase, the team recorded the activity within the animals’ hippocampus. They then used a computer system to translate this neural activity to specific locations within the VR environment.

In the next step, the researchers decoupled the treadmill from the VR system. This meant the rats could not reach the goal by running on the treadmill. Instead, they could only use their brain activity to navigate through the VR environment.

By analysing the activity in rats’ hippocampus in real time during the task, the team were able to update the screen every 100 milliseconds with the animals’ current location in the VR environment, based on what was happening in their brain.

The results reveal the rats could indeed navigate to the goal using just their brain activity.

In a subsequent experiment, the team gave the rats a “Jedi task” in which the animals themselves were stationary but had to direct an object on the screen to a particular goal within the VR environment using only their brain activity. Once again, the rats were able to do so.

I'm not sure objective human fact exists. Just a shared quest to experience the universe, with all its causalities and regressions and entropy. Maybe I just spend too much time around the neurodiverse these days. Often they experience the same things much differently than anticipated. Even math is ultimately just a subjective human construct, a house of cards built and used to attempt to describe the universe in shared language. Accomplished in large part by limiting the scope of what it can describe. It is its own internally premised form of logic, logic itself being a branch of philosophy.

'Objective human fact' isn't a scientific term I'm aware of. The fundamental laws of physics shape our Universe, no matter if there are humans around to discover those laws, or not.

Same with math; we didn't invent math; we discovered it. We invented our specific language of math, mathematical concepts and so on, but the Universe is shaped by fundamental math no matter if humans exist, or not.
 
But science and math are human terms that describe a thing within our(at least some of us) languages and limitations?
 
Yes, obviously our terminology of choice is invented. Just like languages and words are.

Here's an idea: can consciousness evolve without the use or knowledge of language (both inner and spoken language)?
 
Are we distinguishing consciousness from sentient self-awareness? If so, I'd find it difficult to argue that language is required for the ability to perceive and feel. Unless we start getting extremely liberal with the definition of language. There would be that. Then... maybe.
 
Consciousness is on a continuum of complexity. Certainly all living things have some degree of consciousness (awareness of self and surroundings: short version). I would personally extend that continuum back into the world of the non living things.

Non-living things having consciousness?

I see. Some trigger point gets reached. Do you think any animals have consciousness?

How can they not have consciousness?

I just asked Maddy how the Sun is different from the Moon. From her response, I gather it's not something she finds important enough to think about.

Did prehistoric humans have consciousness before we used a spoken language? I'd say yes, as we would have been able to interact with each other and the environment on a primitive level, even if communication was minimal.

I do not think it is a very useful description, but according to Daniel Dennett, the philosopher I quoted in the first spoiler, they do not. I copy the relevant bit here:

Trees cope brilliantly under many conditions without a shred of comprehension; so do rabbits and foxes and elephants, who do many wise things without needing to know why these are wise things to do or when to do them. It is our human capacity to frame why-questions and evaluate candidate answers that sets us apart from the rest of nature, not some apparently magical soul that does the understanding and the feeling, the loving and fearing.

Isn’t this terribly anthropocentric? No, it is properly centered on what matters. Control is the key to life and everything that matters. The more things you can control, the more things can matter to you. Chimpanzees and dolphins are at risk from, but oblivious to, the problems of climate change, economic inequality, pollution, and war, but we alone can think that these problems matter enough to devote our energy to solving them.​

This argument seems consistent, but what real world question is it the answer to? It does little use knowing that 42 is the answer to life the universe and everything without actually knowing what the real question is. In the same way, this is an objective answer to what fits Dennetts definition of conscious, but without knowing what real world problem this is the answer to it is difficult to use this information to make a better world.
 
Elephants have been observed to grieve over both their own species and others. Whales mourn their dead. My own pets have mourned dead family members, whether human, canine, or feline. You don't need a doctorate in psychology to mourn your dead.

I am not sure that is a response to me, but Daniel Dennett would not care. He would not care if elephants cried deeper tears than humans, or if sperm whales could solve higher dimensional maths in their heads for fun, or if humpback whale song was the greatest artistic achievement on earth. As long as they could not create a global economy that changed the atmosphere of the planet, identify that and at least try and fix it they are not conscious.

That is an interesting answer, but it seems less useful than yours, and he is paid to think about things like this.
 
Suppose you have a single human, in all of existence. This single human has let's suppose a certain level of human-like intelligence and a capacity for reasoning, despite never being socialized. If this human lived forever, could this human produce all of the great works of civilization?

Or is that impossible - and to even begin with creating civilization, it is necessary for there to be at least two humans. Possibly then a new meta-intelligence, a hypothetical intelligence, exists from the combined capabilities of both of them. It would seem that combination would be worth more than the sum of its parts, as the humans would not just be able to explore their own soul but each other's.

Now take the infant human. Does the infant human always develop into the full-grown human, intelligent, erudite, capable of contributing to said great works? No. Sometimes the infant human is stunted, or grown into a beast that was never socialized and has become utterly alienated from the world. Other times the human is raised in a circumstance where it is never challenged, and hardly actuated. Generally the human is raised in fact by many humans, and a complex tapestry of the world at large, and thereby comes to be a part of it. Thus does the human progress to reason.

In all of this, even the stunted and incapable humans were "conscious," but perhaps what they weren't was "socially conscious," which is maybe the far more important and key criteria of understanding yourself as part of the world, and being able to influence it on that basis. The more sophisticated your methods of communication and actuation become, the more profound your social consciousness is able to become. And then once you've got society loaded up on the whole thing, you're on the civilization train and your "consciousness" is a sophisticated beast with dreams of society.
 
How one defines consciousness is the key to what one allocates consciousness. The definition one begins with will determine the outcome.

Consciousness: The capability of an "entity" to respond to things outside of itself. As an entity increases in complexity, its capabilities of response increase.

Pretty sure they did; but I was going for how the use/invention of inner though, language and communication evolved our consciousness (that already existed). To use a 2001: A Space Odyssey analogy, the tribe of apes are exposed to the Monolith and one of them suddenly connects a new abstract idea of a weapon/tool to an otherwise worthless bone and the rest is history; the dawn of man.

More than a Million other species exist or have existed on this planet, many of them have been along for considerable longer than humans. But humans and select mammels and birds are - as far as I know - the only species that developed a more advanced level of consciousness; some display empathy towards members of their own and other species, some play, some can look in a mirror and recognize they're looking at a reflection of themselves and so on. Cold blooded animals in particular, wasn't invited to the party.

It seems evolution didn't choose or prioritize the path of more evolved brains, than what was strictly necessary for survival. Perhaps we are kind of a fluke; a lightning in a bottle?
 
Is a thermostat conscious?
:lol: No. the thermostat is not, but I would say that the matter that makes up it has a level of consciousness. Matter does respond to its environment at different levels. Mostly those are chemical or molecular changes and I think of that capability as a very low level of consciousness, but it is a still an "awareness" of things outside itself. I do not imbue consciousness to objects we make like your thermostat, or shoes, or tables. It is that very limited consciousness held by matter that makes many objects we create function. when two molecules/atoms come close there is often a reaction triggered by that proximity. You might call that just physics or chemistry; I would say that the physics and chemistry work because of consciousness. :)
 
According to someone (no one read books anymore anyways),
Consciousness = Feedback.

So if you kick something and nothing comes back at you, this something is not conscious.

Furthermore, and disagreeing with many here,
Spoiler :
I don't believe humans have anything special to them.

Neurons? Electro-chemical circuitry. Wow!
A brain? A big one? A glorious network allowing me to admire fine arts and fear for my destruction.

What we have can not compensate for what we lack.

Put me on a pedestal so I can serve you right!

Literally drove a dude a couple nights ago working in this part of neuroscience, a phd student at ucsf. He was talking about how during REM sleep, their dreams change with their eyes like it’s real, so when their eyes look left the maze view shifts to the left.

Well, we're even then, because I don't care about Daniel Dennett's opinions, and he can stuff them. Elephants are social animals and they suffer when separated from their families and they grieve when other elephants die.

Elephants have mourning rituals. They bury their dead, they visit their dead, and they mourn their dead.

Consciousness: The capability of an "entity" to respond to things outside of itself. As an entity increases in complexity, its capabilities of response increase.

So anything that responds to a stimulus from outside itself has consciousness?

The Moon must have be conscious, then, since there have been geological (whatever the correct term is when discussing the Moon) responses when comets, asteroids, and meteors have crashed into it.

2001 was a story, not a documentary. The sudden realization that a bone could become a weapon doesn't mean that pre-humans never found any other uses for bones. They became a variety of tools and ritual items (there's evidence to indicate that the Neanderthals had spiritual/religious beliefs).

Evolution is survival of the most adaptable, and it doesn't care if a species does or does not develop the ability for abstract thought. As long as it survives to procreate and there's a way for the offspring to mature and procreate, that's all that evolution expects. So yeah, we've gone beyond that, but so have other species.

I dunno... my thermostat has been really annoying lately. At least my socks haven't been playing hide-and-seek in the laundry, so there's that.

However, the thing about molecules and atoms coming close and a reaction being triggered by that proximity... how many thunderstorms do you usually get in your region? I doubt that there's consciousness involved, even though there's a nonsensical story that some people tell naive children about storms: Thunder is what you hear when the angels go bowling.
