I think it's the same thing. You can't have consciousness without qualia and vice versa.

No, qualia are not fundamental to existence, this is an example of Wilfrid Sellars' "myth of the given" - to have a quale of a colour or a shape appearing in your vision you must have a concept of that colour/shape. Qualia in that sense are not prior to cognition. Maybe we can say they are necessary as an element of concept formation and language, ie for sapience.

  • You really don't need a concept of a colour or a shape, and it's a fairly typical academic fallacy to assume you do.

    That's directly confusing experience with categorisation and labelling of experience.

    If you touch a very hot object your nervous system will pull your hand away before your brain registers what's happening. The qualia of pain are pre-conceptual, preverbal, and precranial, and your consciousness only catches up later.

    • Surely this implies exactly the opposite - you don't register the pain, don't feel it, until after you pull your hand away. It's a reflex action in response to heat. Qualia require a brain to process sensory input.

    • reflexes have nothing to do with qualia. you can differentiate objects without knowing what is a triangle and what is a square, or that this colour is red. but I think qualia as commonly understood involve concepts in a way that means they are not immediate experience in some kind of cartesian sense. We speak of them as categorised. certainly the way people commonly speak about them they are very carefree about invoking "the qualia of a horse" or some other specific object.

  • Not fundamental to existence but fundamental to consciousness.

    Theoretically the person sitting next to you could be a zombie, no qualia, the lights are off, he's just having a conversation with you with nothing going on behind the scenes. And there's no way to tell, except that it's reasonable to extrapolate that since you feel something, he probably does too.

    • My argument is that qualia are actually cognitive artefacts bound up with language, not the base elements of "what it is to be" you or me, which is how people often speak of them, so the p-zombie concept is a bit nonsensical to me.

Ok pain might be a bad example because a robot may not have a sense of it borne of evolution. But what about “red”? If I make a robot that 99.9% correctly identifies red objects, then I think it is fair to me to say it has a concept of “redness”.

Some philosophers believe that our human emotional connection to redness is special. These are the people talking about qualia. My belief after much reading is that it is not special. I /do/ believe that the human ability to tie our senses so deeply together synthetically and into our emotional and memory is special. My robot cannot write a poem about how the redness of a flower reminds them of their mother’s funeral. But now we are talking a matter of degrees, not qualia.

  • Isn't what makes the experience of love special the experience of love? a robot can hold hands and kiss and bring flowers home far more efficiently than i can. is that what love is? A robot CAN write a poem about how the redness of a flower reminds them of their mother’s funeral. But the outward signal of grief is not evidence of an internal experience of it.

    • I’ll bite the bullet: if a robot has a complicated enough internal representation of the world, it may very well develop a concept of love (or “care”, or “noticing”, or “intention”. Love is such a slippery word…) that we would have to trust.

      Imagine a cat-sitting robot. The robot can differentiate between individual cats. It learns how to play with the cats and feed them in in their preferred way. The cats grow to trust the robot and enjoy its company. When the cats become sick and old the robot knows how to help them and ease their pain. Over decades The robot remembers cats in its care that have died, and new cats spark recognition of previous cats it has known. It becomes better at caring for a wider range of cats as its experience grows. The cats cry out when it leaves. When there are no cats around the robot remains motionless, but springs into action and play as soon as cats are around. Children would describe the robot as “happy”.

      If after some decades I smash it with a hammer and recycle the pieces, am I killing something? Are its internal representations and control systems not a kind of thing that produces “qualia”?

    • What's really a head trip is that I don't actually know another human is experiencing grief either. They could be a sociopath and not actually feel emotions, but are pretending to in order to benefit them in some way.

  • But does the robot identify them in your view, or in its view?

    If in your view, then you created a tool for yourself. Like a Geiger counter.

    If in its view, ask it what it thinks about consciousness and qualia.

    • I’ve asked the slugs and the worms and starfish and amoebas and nematodes and fish about their experience, I’m just waiting to hear back.
