The Transparency of Experience Argument 143 |
This is one of the main arguments in the philosophy of perception and |
epistemology. It was canonically presented by G. E. Moore. This argument |
challenges the thesis that by having sensations we are directly conscious of |
features of sensations or experiences. It makes explicit a commonsense |
intuition on what appears to be diaphanous by having sensations, that is, |
sensory awareness relations β in the words of Moore: β in respect of which |
all sensations are alike β (444). In general, the argument is about what it is |
epistemically available by having sensations. |
In principle, this is an epistemic argument, but it has metaphysical conclusions |
depending on the theoretical framework. In general, the transparency |
of experience argument (henceforth, TEA) is often understood as going |
against the reduction of the contents of sensations (say, colors) to a kind |
of β veil of perception β or β mental paint β (Harman, β Intrinsic Quality β and |
β Explaining β ) β in other words, in Berkeley β s empiricism, something constituting |
the external world itself. Other philosophers have criticized such |
a conclusion (see Block). |
The intuition framing the TEA was sketched by Moore as follows: when |
β we try to fi x our attention upon consciousness and to see what, distinctly, |
it is, it seems to vanish: it seems as if we had before us a mere emptiness. |
When we try to introspect the sensation of blue, all we can see is the blue: |
the other element is as if it were diaphanous β (Moore 450). This quote is |
often used to uphold the following: (a) An epistemological inference: by |
merely having sensations, we are never able to introspect sensory awareness |
relations; therefore, we are directly aware of what our sensations are about, |
for example, the color green (Tye Ten Problems , 30). (b) A metaphysical |
inference: by merely having sensations, we are never able to introspect |
sensory awareness relations or features of sensations themselves; therefore, |
there are no perceptual intermediaries. The consequent of (a) is not necessarily |
the consequent of (b), despite the antecedent being the same. To |
clarify the relations between such antecedent and such consequents is the |
core issue in the debate (see Dretske, Harman β Explaining, β Block, and |
Shoemaker). The antecedent was not defended by Moore. I shall return to |
this issue below. |
The abstract structure of the reasoning behind the TEA is as follows: |
P1. [Content Premise:] If a subject, S, has a sensation, v , v is a sensation of |
x . |
P2. [Transparency Premise:] By having v , S only has direct knowledge of y . |
C1. [Epistemological conclusion] S is directly aware of y . |
C2. [Metaphysical conclusion] |
(If v = y or ( y = P and Pv )) There are y - like entities between S and x . |
(If v β y or ( y = P and τ Pv )) There are no y - like entities between S and x . |

The TEA is not an argument concluding that transparency is true but |
takes it as a premise. The argument has ab initio two plausible interpretations |
depending on the metaphysical character and role ascribed to that |
what sensation are about: (i) The strong content version: what fi gures as |
the content of a sensation is a subject - independent particular and its properties. |
(ii) The weak content version: what fi gures as the content of a sensation |
is a subject - dependent entity (e.g., sensory properties, qualia , and so on). |
Philosophers endorsing (i) appeal to TEA to justify objective (physical) |
relations between sensations and external mind - independent physical entities |
(Harman β Intrinsic, β Dretske, and Tye Consciousness ]. Accordingly, |
philosophers endorsing (ii) appeal to TEA to justify (mental) relations |
between sensations and mind - dependent entities (Robinson IX Β§ 3). Further |
on, β transparency β has ab initio two plausible interpretations depending |
on the epistemic role ascribed to sensations (see Kind): (i * ) Strong transparency: |
by having a sensation, V, one cannot introspect features of v , but just |
what v is about. (ii * ) Weak transparency: by having a sensation, V, one |
could introspect some feature of V. The latter was the version endorsed by |
Moore and the former is the antecedent of the epistemological inference |
and the metaphysical inference. |
(i) and (i * ) can be coupled, and we obtain a version of TEA motivating |
direct realism. Call this version strong TEA: by having a sensation, V, one |
cannot introspect features of V but just the subject - independent entity that |
v is about (Tye Consciousness and Harman β Intrinsic, β 39). It might be |
synthesized as follows: |
P1. If a subject, S, has the sensation, V, then, V is a sensation of a subject - |
independent entity, X (strong content version). |
P2. By having V, S cannot introspect features of V but just what V is about |
(strong transparency). |
C1. There are no perceptual intermediaries between S and X (metaphysical |
inference * ). |
Accordingly, (ii) and (ii * ) can be coupled, and we obtain a version of |
TEA motivating idealism. Weak TEA holds that by having a sensation, V, |
one is sensory aware of a mind - dependent entity and one could introspect |
