Now that I have established the importance of systematized critical thinking as a normative school of thought (Nyaya) in and of itself. Let me briefly mention some the key texts of Nyayasutra...the central document of this school.
---------------------------------------------------------------------------------------------------------------------
1.
Supreme felicity is attained by the knowledge about the true nature of 16 categories.
a) Means of right knowledge (pramana)
b) Object of right knowledge (prameya)
c) doubt (sansaya)
d) purpose (proyojana)
e) observational data (drstanta)
f) established tenet (siddhanta)
g) the parts of a demonstration (avayava)
h) suppositional reasoning (tarka)
i) final conclusion (nirnaya)
j) truth-directed discussion (vada)
k) victory-directed debate (jalpa)
l) destructive debate (vitanda)
m) sophistical rejoinders (hetvabhasa)
n) quibbles (chala)
o) false reasons (jati)
p) defeat situations (nigrahasthana)
-------------------------------------------------------------------------------------------------------
All the 16 categories are not associated with any specific beliefs or worldviews, but rather the means and praxis by which truth about things can be ascertained. Thus the first two is about the methods that deliver correct knowledge and identifying the proper objects of knowledge. The next 7 is about constructing proper justifications for knowledge in public discourse and the final 7 are the various good and bad ways of going about conducting such a public discourse. Nyaya therefore is not a set of worldview positions but a systematic practice of properly striving after truth that is done in a community setting.
Crucially the next verse asserts that honestly doing the practice of Nyaya will guarantee moksha.
---------------------------------------------------------------------------------------------------------------------------------------------------------
2. Pain, birth, activity, faults and misapprehension - on successive annihilation of these in the reverse order, there follows releasing.
Commentry (Vatsyayana):
Misapprehension, faults, activity, birth and pain, these in their uninterrupted course constitute the cycle of samsara. Release, which constitutes in the self getting rid of the world, is the condition of supreme felicity marked by perfect tranquility and not tainted by any defilement.
A person, by the true knowledge of the 16 categories, is able to remove his misapprehensions. When this is done, his faults, viz. affection, aversion and apathy, disappear. He is no longer subject to any activity and is consequently freed from transmigration and pains. This is way in which his release is effected and supreme bliss secured.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
I find it extremely interesting (and cause for good cheer) that intellectual striving after truth through rational discourse is considered to have the same salutary effect on the Self as devotion to God, self-less action and self-realization through yoga. It is a testament to the extremely broad vision Hinduism has as to what exactly constitutes leading a holy life.
What do you guys think? Do you agree with this idea of dharmic practice through intellectual sadhana? Thoughts?
Of the 16 categories of study in Nyaya the first is the study of the
means of knowing (pramana). The first and most important method of knowing is through
sense-perception. Much of Nyaya (and indeed Indian) philosophy is devoted to understanding perception and how it gives us reliable knowledge about the world.
N
yayasutra 1.1.4 defines perception as:-
Perception is an awareness which, produced from the connection between sense-organ and object, is non-verbal, non-errant, and determinate in nature.
Certain things immediately stand out.
1) Perception is a from of conscious awareness.
2) It is not a propositional awareness that comes from hearing or speaking sentences. Hence the term non-verbal. Thus hearing the words "there is a cow in your garden" does not create an awareness of the cow that can be called "perception" of the cow.
3) Instead it is a physical/psychological awareness caused by "contact" between the perceiving faculty (eyes, ears etc.) and the object. Only then can one say that a seeing, a hearing, a tasting sort of perception has occurred.
4) The awareness must be a true, non-errant and determinate (i.e. not vague) in order to be called a perception. T
hus Nyaya, defines that only true forms of awareness created by sense-faculties can be called perceptions. Illusions, mirages, vague sightings can't be called perceptions.
Vatsayana in his commentry gives two kinds of sense-faculty induced awareness that are not perceptions,
-----------------------------------------------------------------------------------------------------------------------------------------------------
During the summer the flickering rays of the sun intermingled with the heat radiating form the surface of the earth come in contact with the eyes of a person at a distance.
Due to this sense object contact, there arises an awareness of water. Such an awareness can be mistaken as perceptual, hence the clause non-errant.
An errant one is of that wherein it is not. A non-errant one is of that wherein it is - this latter is perception.
Perceiving with the eyes an object at a distance, a person cannot decide whether it is smoke or dust. Such an indecisive awareness resulting from sense-object contact might be mistaken as perceptual, hence the clause "determinate in nature."
--------------------------------------------------------------------------------------------------------------------------------------------------------------
Many other schools, including the Buddhists would argue that in cases of seeing a mirage, we are still perceiving something...only we are falsely attributing the features we are perceiving (shimmering rays of light) to an object that is not there (water). But such a move entails that perception is a post-hoc rational reconstruction of some deeper sort of awareness caused by the sense-faculties "below" our consciousness where the "true" perception is hidden. Buddhists love that idea and Nyaya hates it.
Thus for Nyaya,, its a far more reasonable move to cut of the head of the serpent right there and then and state that people are simply mistaken that they are
perceiving something when they "see" a mirage for example.
Dr. Ganeri in his analysis of Nyaya ideas of perception explicated the idea in terms of the following logic:-
--------------------------------------------------------------------------------------
A person S's
perception is of an object X if and only if:
(4) For some (object or property category) F, S does
see X as an F, where
S sees X as an F if and only if :
(1) S's perception stands in relation R with x.
(2) This relation R is physical/psychological (non-verbal)
(3) F(X) is true. (i.e. X is indeed an F)
----------------------------------------------------------------------------------------------------------
Thus we have a technical and well-fleshed out definition of perception as a form of clear seeing and that which is free of all interpretations and propositional constructions.
It would be interesting to compare this account of perception with more modern ones in western philosophy. Anybody has any idea?
