What is consciousness? I would say the experience of life, the Merriam-Webster says it is
being characterized with sensation, perception, volition and thought (Merriam-Webster, 2023).
Philosophical schools are notoriously ambiguous when attempting to define this concept, my
they create the unanswered question of why there is an experience from a set of functions when
the functions, dynamics and structures can be explained but not the experience itself (Weisberg,
accessed 2023). The hard problem of consciousness is in distinguishing between why any
physical state is conscious rather non-conscious, the problem of explaining what consciousness
I believe that consciousness is a hard problem for multiple reasons: its subjectivity, qualia
of consciousness, and variability. I will be expanding on these reasons over the course of this
paper using reductionist and consciousness theories. A common theme amongst all these factors
reduced.
Subjectivity. Part of this reason is the mind-body problem, which I will be addressing
from a reductionist perspective. The way our minds paint experiences differ from person to
person, when you read this there might be a voice in your head or an unconscious processing of
the words on the screen (Chalmers, 1995). Being alive might feel like a music video, a collection
The identity theory proposes that consciousness occurs in the brain (Place, 1956). This
proposal by the identity theory uses neuroscience to explain how neural activities give rise to
consciousness, however it is important to know that when U.T Place proposed this thesis it was
not to say that conscious experiences like dreams, fantasies, etc are reducible to cognitive
statements but rather that consciousness happens in the brain as an identity of composition rather
than one of identity (Place, 1956). This means that the brain is not consciousness but rather there
is a systematic correlation between the brain and consciousness, evidence for this is from our
own development, we are conscious of things we learn about, it is not a mythological experience
on a different field but rather a physical phenomenon that gives rise to this abstract experience of
consciousness, the theory hence states that conscious experiences can be explained by brain
This is a consistent issue with reductionist views aiming to make sense of consciousness,
they deal with the easy problems of consciousness rather than the hard problem (Chalmers,
1995). However, the way we experience things as mentioned earlier is not the same and in fact is
too grande to be explained by brain processes, it is also one directional in the sense that with a
conscious person there can be an explanation for the brain processes however if given a brain
map or evaluating the brain processes of an unconscious person there is no way to explain the
conscious experience of the person. Another issue lies in multiple realizability, that is, the
emergence of the same mental state from different physical experiences, using the brain map
example, if people had similar brain maps there would be no way to realize that they emerged
from different experiences which is problematic long term especially for situations like
determining if people are lying, if they do not believe they are lying, their brain states will be
There is a nature of subjectivity to consciousness and reductionist views threaten to eliminate the
Qualia of consciousness. To expand on this point, I will use Descartes dualism. The
Cogito, “I think therefore I am” coined by Descartes gives a clue into consciousness that is; it is
self-evident in that which is conscious (Descartes, 1996). With the cogito, Descartes separates
the soul from the body, given this dualist view, it is this non-physical substance; the soul that is
The reductionist identity theory does not propose that consciousness can be observed by
the brain and acknowledges the lack of continuity between consciousness and electric charges in
the brain yet it says that consciousness and the brain are of the same event (Place, 1956). The
reductionist theory, computationalism can give more insight on why that is.
The computationalism theory believes that the brain computes consciousness, in this
theory, the brain acts as a form of CPU, creating schemas, structures and predictions about how
the earth works and how we can relate to the world around us, this includes behaviours, thought
patterns, interpretations of sight, sound, taste, scents, etc (Turing & Alan, 2007), I agree with this
on a on a strictly biological level, not including the subjective ways we experience these
sensations. Given this explanation it makes sense how consciousness and brain activity though
not linked are related, however like other reductionist theories, the computationalist theory uses
the development of artificial intelligence to suggest that these systems can generate cognitive
function similar to consciousness (Turing & Alan, 2007), I disagree with this point because it
takes us back to the philosophical zombie, to say that consciousness can emerge from purely
physical processes negates the philosophical agreement that we are not zombies. If we are
intelligent machines as the computational theory suggests we would have no qualia, no spark for
lack of better language, the qualia of consciousness is a substance that cannot be defined, it just
is.
The qualia of consciousness and its meaning which is beyond articulation has made me
over the course of this paper entertain the thought that the perfect God Descartes said exists
outside of us is just pure consciousness (Descartes, 1996), and as life came to be in the universe,
this pure consciousness that has always been is present through the stretch of the universe, I am
The question of animal consciousness is important to our conversation because if animals are
conscious it will change the way we view the structure of consciousness and the nature of
consciousness as a whole. National geographic interviewed Carl Safina on his book beyond
words, in the book he dives into the consciousness of animals (Worrall, 2015). Philosophers like
Descartes have removed animals from having access to consciousness given that they do not
speak or think, the cogito reveals a flaw in his thinking, if I think therefore I am, and there is no
way to know of anyone else’s existence but mine because it is my experience why do we as
humans get to decide that animals are not conscious when we do not know if they think therefore
they are. Carl Safina’s book reveals that animals have their own individual personalities which is
obvious to anyone who would observe them rather than observation through manipulation via
not a prerequisite for consciousness given that there are humans who are conscious but do not
experience empathy, it is just another extension of consciousness. Animals mourn for their lost
loved ones, they are vengeful, wolf packs disband if their alpha dies sometimes, indicating a
social awareness beyond survival instincts as this disband reduces the survival rate of their young
(Worrall, 2015). Reductionists would be inclined to say that the expression of these emotions in
animals are the result of neural activity, to this I say, the same way we have subjective
experiences which make it hard to define consciousness is the same way animals do, the
variation in personalities means that there are different experiences which means there is a
consciousness that is inaccessible to us as humans given the language barrier that would have
otherwise given us insight into how they think and what they think. If animals are conscious, our
Though given a hard time I believe that reductionist theories true to their intention, which
is to bring about a unification and coherence of broad concepts are beneficial in explaining the
theories should direct their attention in explaining why we as humans are conscious of our
qualia as the intrinsic nature of consciousness and variability as the varying experiences of
consciousness.
humanity, despite this common experience of consciousness, its nature and quality varies. The
Fred example of Frank Jackson shows that even our perceptions of things in the world like
colour differ, though seemingly minuscule this changes the individual's consciousness as a whole
(Jackson, 1982). A more feasible example is my thought process, when I wake up from sleep I
am immediately already aware of multiple thoughts in my head, sometimes even before I wake
sympathetically shocked that I had to experience ask that was going on in my mind yet I was
sympathetic towards her because I couldn’t imagine not being constantly conscious of what was
going on in my mind, this anecdotal example is just one of the many ways in which we differ in
the quality of consciousness, another example is my two friends who are able to identify the
smell of people’s pheromones yet I do not experience this and have no idea what my family
‘smells’ like. The varying experiences of consciousness makes it hard to define consciousness.
Factors like education, social development and economic brackets also affect the nature
consciousness that is available for testing. The different worldviews that we have as individuals
give us all unique consciousness informed by our own personal experience. The hard problem of
that consciousness is fundamental and should not be reduced but instead accepted as a universal
reality similar to gravity, and other laws of physics that guide our understanding of the universe
(Chalmers, 1995).
