via the object of ostension. According to Chalmers, there is another phenomenal concept5 which is neither
relational nor indexical, rather completely intrinsic, which can be called a pure phenomenal concept or R.
When Mary looks at the red for the first time, she gets to know what it is like to see red, and that is essentially
her subjective feeling. In a way that can be regarded as private, also. The concept R is all the way different
from redC, redI, and E. We form the belief that redC = R, that is, this feature is caused in the community by red
things, and similarly, we are also inclined to postulate that redI = R. However, we might also hold the belief
that E = R by the denotation of the object. The relation between redC, redI, and E on one hand and R on the
other is not a priori, because the pure phenomenal concept is independent of them. Here, one can reasonably
ask how the phenomenal concept can ever be independent as such when it is initiated by an external object (at
least in the case of Mary). To find out this answer, first we need to understand that what we feel is not
governed by the external world rigidly. My phenomenal concept of red is indeed about the external tomato, but
one can have the same experience in the absence of the object altogether. Even the same red can be felt
differently in two subjects, which yields two different phenomenal concepts for them. Hence, we must accept
that the pure phenomenal concept or R is strictly subject-specific.
Inverted Mary
Consider Inverted Mary, who is a physical–functional twin of the famous scientist Mary, but the only
difference is that her colour spectrum is inverted. Like Mary, inverted Mary also gets aware of something new
when she encounters the tomato for the first time. But there are obvious differences. Where Mary learns that
tomato causes phenomenal redness or R (what we call), inverted Mary learns that tomato causes phenomenal
greenness or G (what we call), though she is uttering it red. Now, if we apply the previous concepts in this
context, then we will find out that for Mary redC = R, redI = R and E = R, but for Inverted Mary redC = G, redI
= G and E = G. Even if inverted, Mary says, “Ah! Now I know what it is like to see red.” She possesses the
concept of green, though her denotation is red. It all indicates one thing: we cannot grasp what is inside by
something that is quite external, such as the use of language. No matter how much effort we put into holding it,
there will always be something that will come out of the fist.
Final Remark
It is almost like a slogan that communication is the key to living in society, be it verbal or nonverbal
(behavioural). Apart from that, we all need to express ourselves. If our feelings get hidden inside and never
come to the surface, that may hinder our growth as human beings and, in turn, the whole species. Living in this
world, we get acquainted with so many experiences every time that make us realize the famous coinage “what
it is like to have a particular experience”. Philosophers, who have tried to refer to pure phenomenal concepts in
other terms (indexical, relational, etc.), are not always against the phenomenal state. Rather, what they want to
criticise is the private subjective existence of phenomenal concepts. For them, something to be subject-specific
does not mean that it is private. So, they have introduced the notion of interpersonal communication to grasp
the inner through the outer.
I am also not against the communication of what is in the mind, and I want to shout out loud in front of the
world what is inside, but unfortunately, I cannot. Because I do not feel that the linguistic concepts are enough
to do justice to the phenomenal concepts. First, in the case of inverted Mary, she does not even know she has a
radically different phenomenal concept compared to the community. Then how could it be registered by the
paradigms of language? Secondly, two subjects (normal) from the same community can have two different
phenomenal concepts regarding the same object. Imagine the typical taste of bourbon whiskey, which,
according to some subjects, is sweeter than regular whisky, while others find it completely normal, which
makes them form different concepts around it. This point can be countered by the claim of “form of life”, that
is, one is typically used to with a certain kind of taste, while the other is not. If we consider this claim, we
cannot rule out completely the probability of different phenomenal experiences of the same object. Thirdly, the
same subject may have different phenomenal experiences regarding an object with different intervals of time
or context. For example, the typical homemade rice and lentils give us a completely different experience when
it is consumed after a whole day of fasting, which in turn gives rise to a particular type of phenomenal concept.
But for some other day, it might be experienced not so differently. Finally, our linguistic vocabulary is too
short to grasp the phenomenal concepts. Imagine the use of the word ‘happy’, we refer to it to denote many
