Read David Chalmers’ catalog of conscious experiences: 

Chalmers, David, J. “A catalog of conscious experiences.” in Keith Frankish, ed., Consciousness. 2nd ed. Open University (2010), pp. 182-7.

Explore your own consciousness.  Go through the list, catalog some examples, and reflect on the following questions.  

· If consciousness is physical, why can’t other people see my conscious experiences or measure them? 

· If I built a robot that is an exact duplicate of me, could that robot feel these conscious experiences? 

· What are conscious experiences actually? 

· If conscious experiences are just neurons firing in my head then how do I explain ideas like “intention” or “imagination”? 

· If I were to describe my mind as a kind of computer or Turing-Machine, then what exactly are these conscious experiences?

1 Conscious experience can be fascinating to attend to. Experience comes
in an enormous number of varieties, each with its own character. A far-from-
complete catalog of the aspects of conscious experience is given in the
following pretheoretical, impressionistic list. Nothing here should be taken
too seriously as philosophy, but it should help focus attention on the subject
matter at hand.

2 Visual experiences. Among the many varieties of visual experience, color
sensations stand out as the paradigmexamples of conscious experience, due to
their pure, seemingly ineffable qualitative nature. Some color experiences can
seem particularly striking, and so can be particularly good at focusing our
attention on themystery of consciousness. Inmy environment now, there is a
particularly rich shade of deep purple from a book on my shelf; an almost
surreal shade of green in a photograph of ferns on my wall; and a sparkling
array of bright red, green, orange, andblue lights on aChristmas tree that I can
see throughmywindow.But any color canbe awe-provoking ifwe attend to it,
and reflect upon its nature.Why should it feel like that?Why should it feel like
anything at all? How could I possibly convey the nature of this color
experience to someone who has not had such an experience?

3 Other aspects of visual experience include the experience of shape, of
size, of brightness, and of darkness. A particularly subtle aspect is the
experience of depth. As a child, one of my eyes had excellent vision, but the
other was very poor. Because of my one good eye, the world looked crisp and
sharp, and it certainly seemed three-dimensional. One day, I was fitted with
glasses, and the changewas remarkable.Theworldwasnotmuch sharper than
before, but it suddenly lookedmore three-dimensional: things that had depth

before somehow got deeper, and the world seemed a richer place. If you cover
one eye and then uncover it, you can get an idea of the change. Inmy previous
state, I would have said that there was no way for the depth of my vision to
improve; the world already seemed as three-dimensional as it could be. The
change was subtle, almost ineffable, but extremely striking. Certainly there is
an intellectual story one can tell about howbinocular vision allows information
from each eye to be consolidated into information about distances, thus
enabling more sophisticated control of action, but somehow this causal story
does not reveal the way the experience felt. Why that change in processing
should be accompanied by such a remaking of my experience was mysterious
to me as a ten-year-old, and is still a source of wonder today.

4 Auditory experiences. In some ways, sounds are even stranger than visual
images. The structure of images usually corresponds to the structure of the
world in a straightforward way, but sounds can seem quite independent. My
telephone receives an incoming call, an internal device vibrates, a complex
wave is set up in the air and eventually reaches my eardrum, and somehow,
almost magically, I hear a ring. Nothing about the quality of the ring seems to
correspond directly to any structure in the world, although I certainly know
that it originated with the speaker, and that it is determined by a waveform.
But why should that waveform, or even these neural firings, have given rise to
a sound quality like that?

5 Musical experience is perhaps the richest aspect of auditory experience,
although the experience of speechmust be close.Music is capable of washing
over and completely absorbing us, surrounding us in a way that a visual field
can surround us but in which auditory experiences usually do not. One can
analyze aspects ofmusical experience by breaking the soundswe perceive into
notes and tones with complex interrelationships, but the experience of music
somehow goes beyond this. A unified qualitative experience arises from a
chord, but not from randomly selected notes. An old piano and a far-off oboe
can combine to produce an unexpectedly haunting experience. As always,
when we reflect, we ask the question: why should that feel like this?

6 Tactile experiences.Texturesprovide another of the richest quality spaces
that we experience: think of the feel of velvet, and contrast it to the texture of
cold metal, or a clammy hand, or a stubbly chin. All of these have their own
unique quality.The tactile experiences ofwater, of cotton candy, or of another
person’s lips are different again.

7 Olfactory experiences. Think of the musty smell of an old wardrobe, the
stench of rotting garbage, the whiff of newly mown grass, the warm aroma of
freshly baked bread. Smell is in some ways the most mysterious of all the
senses, due to the rich, intangible, indescribable nature of smell sensations.
Ackermann (1990) calls it ‘the mute sense; the one without words’. While
there is something ineffable about any sensation, the other senses have
properties that facilitate some description. Visual and auditory experiences
have a complex combinatorial structure that can be described. Tactile and
taste experiences generally arise from direct contact with some object, and a
rich descriptive vocabulary has been built up by reference to these objects.
Smell has little in the way of apparent structure, and often floats free of any
apparent object, remaining a primitive presence in our sensory manifold.
(Perhaps animals might do better [Figure 1].) The primitiveness is perhaps
partly due to the slot-and-key process by which our olfactory receptors are
sensitive to various kinds of molecules. It seems arbitrary that a given sort of
molecule should give rise to this sort of sensation, but give rise it does.

8 Taste experiences. Psychophysical investigations tell us that there are only
four independent dimensions of taste perception: sweet, sour, bitter, and salt.
But this four-dimensional space combineswithour sense of smell toproduce a
great variety of possible experiences: the taste of Turkish Delight, of curried
black-eyed pea salad, of a peppermint Lifesaver, of a ripe peach.

9 Experiences of hot and cold. An oppressively hot, humid day and a frosty
winter’s day produce strikingly different qualitative experiences. Think also
of the heat sensations on one’s skin from being close to a fire, and the hot-cold
sensation that one gets from touching ultracold ice.

10 Pain. Pain is a paradigm example of conscious experience, beloved by
philosophers. Perhaps this is because pains form a very distinctive class of
qualitative experiences, and are difficult to map directly onto any structure in
the world or in the body, although they are usually associated with some part
of the body. Because of this, pains can seem even more subjective than most
sensory experiences. There are a great variety of pain experiences, from
shooting pains and fierce burns through sharp pricks to dull aches.

11 Other bodily sensations. Pains are only themost salient kind of sensations
associatedwith particular parts of the body. Others include headaches (which
are perhaps a class of pain), hunger pangs, itches, tickles, and the experience
associated with the need to urinate. Many bodily sensations have an entirely
unique quality, different in kind fromanything else in our experience: think of
orgasms, or the feeling of hitting one’s funny bone.There are also experiences
associated with proprioception, the sense of where one’s body is in space.

12 Mental imagery. Moving ever inward, toward experiences that are not
associated with particular objects in the environment or the body but that are
in some sense generated internally, we come tomental images.There is often a
rich phenomenology associated with visual images conjured up in one’s
imagination, though not nearly as detailed as those derived from direct visual
perception. There are also the interesting colored patterns that one gets when
one closes one’s eyes and squints, and the strong after-images that one gets
after looking at something bright. One can have similar kinds of auditory
‘images’ conjured up by one’s imagination, and even tactile, olfactory, and
gustatory images, although these are harder to pin down and their associated
qualitative feel is usually fainter.

13 Conscious thought. Some of the things we think and believe do not have
any particular qualitative feel associatedwith them, butmany do.This applies
particularly to explicit, occurrent thoughts that one thinks to oneself, and to
various thoughts that affect one’s stream of consciousness. It is often hard to
pin down just what the qualitative feel of an occurrent thought is, but it is
certainly there. There is something it is like to be having such thoughts.

14 When I think of a lion, for instance, there seems to be a whiff of leonine
quality to my phenomenology: what it is like to think of a lion is subtly
different from what it is like to think of the Eiffel tower. More obviously,
cognitive attitudes such as desire often have a strong phenomenal flavor.
Desire seems to exert a phenomenological ‘tug’, and memory often has a
qualitative component, as with the experience of nostalgia or regret.

15 Emotions. Emotions often have distinctive experiences associated with
them. The sparkle of a happy mood, the weariness of a deep depression, the
red-hot glow of a rush of anger, themelancholy of regret: all of these can affect
conscious experience profoundly, although in a much less specific way than
localized experiences such as sensations.These emotions pervade andcolor all
of our conscious experiences while they last.

16 Other more transient feelings lie partway between emotions and the
more obviously cognitive aspects of mind. Think of the rush of pleasure one
feels when one gets a joke. Another example is the feeling of tension one gets
when watching a suspense movie, or when waiting for an important event.
Thebutterflies in one’s stomach that can accompanynervousness also fall into
this class.

17 The sense of self. One sometimes feels that there is something to
conscious experience that transcends all these specific elements: a kind of
backgroundhum, for instance, that is somehow fundamental to consciousness
and that is there even when the other components are not. This
phenomenology of self is so deep and intangible that it sometimes seems
illusory, consisting in nothing over and above specific elements such as those
listed above. Still, there seems to be something to the phenomenology of self,
even if it is very hard to pin down.

18 This catalog covers a number of bases, but leaves out as much as it puts
in. I have said nothing, for instance, about dreams, arousal and fatigue,
intoxication, or the novel character of other drug-induced experiences.There
are also rich experiences that derive their character from the combination of
two or many of the components described above. I have mentioned the
combined effects of smell and taste, but an equally salient example is the
combined experience of music and emotion, which interact in a subtle,
difficult-to-separate way. I have also left aside the unity of conscious
experience – the way that all of these experiences seem to be tied together as
the experience of a single experiencer. Like the sense of self, this unity

sometimes seems illusory – it is certainly harder to pin down than any specific
experiences – but there is a strong intuition that unity is there.
