Senses
Perception – The Interpretation of the Logical
School
In early Buddhism, the
origin of a perception was explained as an interdependent between
three elements; an external object, a sense organ and pure
consciousness. This produces a sensation resulting in the formation
of an image, concept or a judgment by the element of conception.
The element of pure consciousness is present in all cognition. It
is the sixth sense organ. The mind/intellect is a part of this
organ.
Here the soul of the
eternalist that lights up the external organs and make the whole
process of cognition conscious is dropped. The whole process of
coordinating the external organs and the internal operation of the
mind is replaced by the sixth organ. This organ, the pure
consciousness is employed in watching the operation of the mind
perceived by ourselves which is the special objects of the sixth
sense. It only assists the work of the other senses in the
perception of external objects. It is thus a stream of pure
consciousness cognizing all mental phenomena directly and external
object indirectly.
Dignaga was led to abolish
the sixth sense and to replace the physical sense organ by pure
sensation. The perception of an object was explained as a moment of
pure sensation followed by the construction of the image of the
object by the Understanding, a mental or intelligible
sensation.
The logicians believe that
what a thing is in itself, what its essence is can never be
express. It does not exist. We can only know things by their
relations. What the colour blue is, we will never know. We can only
divide all colours in blue and non-blue. The non-blue can be
further divided into other varieties of colours. The definition of
blue is that it is non-blue and vice versa.
Sense perceptions or
cognition by the senses is only the first moment of perception.
Subsequence operation when attention is aroused is just a process
of recognition. When attention is aroused it is not pure sense
perception anymore. The main function of sense perception is to
signalize the presence of an object in the ken, its mere presence
and nothing more. The construction of the image of the object is
another function by another agency, the Understanding. The salient
feature of sense perception is that, it is non constructive. Sense
perception shorn of all its memory is pure sense perception. It is
also a valid source of knowledge.
Perception is more than just
sense perception alone, it also mean direct knowledge or intuition
as contrasted with indirect knowledge by concepts through our
Understanding. Our Understanding is also a source of illusion since
it constructs image of reality instead of a direct
intuition.
Sense perception is one
variety of intuition. There is also another form of intuition, an
intelligible one. But it is a faculty of a saint rather than that
of an ordinary humanity. This intelligible intuition is present in
every perception. It is the 2nd moment that follows on each
pure sensation before our understanding takes over and constructs
an image of each pure sensation.
Dharmakirti says – That
sensation is something quite different from productive imagination
and can be proven just by introspection. Now, if we are to stare at
a patch of colour and withdraw all our thoughts from it and become
as though unconscious of it, this will be the condition of pure
sensation. If we than to awakened from that condition and begin to
think, we will notice a feeling of remembering that we have an
image before us, but we did not notice it whilst we are in the
foregoing condition because it was pure sensation.
We do have an unmistakable
feeling of our personal identity, a sense of our own self. This
feeling accompanies every state of our consciousness. When we see
some object and at the same time are conscious of a pleasant
feeling arising, it is a feeling of the condition of our ego. It is
a direct self-perception in being self-conscious. It is something
additional accompanying every mental state, different from the
perceived external object. This something is our own ego. It is a
direct, non constructive and not an illusion. It therefore falls
under the definition of sense-perception as one of its
varieties.
It is a fundamental tenet of
the Logical school that every consciousness is self-consciousness.
Consciousness can only be known by itself. It is self-luminous
whereas matter and external objects can only be known through
consciousness. A cognition of an external object is a cognition of
that cognition, it is an awareness of our awareness. Dharmakirti
point out that such mental state as pain and pleasure are of the
nature of consciousness and they cannot be cognized by other
cognitions. It does than follows that all cognitions and mental
states are self cognized. That all volition is, on the one hand
connected with some object and on the other side self-conscious. It
is maintained that if we did not know that we have perceive a blue
patch, we never would have perceived it. Thus, all consciousness,
mental phenomena, images, ideas, feeling and volitions are
self-conscious in themselves. Self-consciousness in this sense is
synonymous with life.
In Buddhist logic, the two
diverse elements of a non-constructive pure sensation and a
constructive or conceptual synthesis, together with the theory of
introspection and Buddhist Nominalism is the basic fundamental
feature on the subject of Buddhist epistemology.
