Is study of Nyaya at an introductory level useful?

A participant (not mentioning name because I have not taken permission) in Nyaya-sah-adyayan WhatsApp group wrote the following:

  1. I have a question (and believe me I have no mischief in mind) where is this knowledge (knowledge of Nyay Darshan) going to benefit us in our practical (day to day) life and how?
  2. Why should a learner invest time and money on it?
  3. I am an Educator (if not an Educationist) and my main “Business is to do workshops for Teacher’s motivation, Teacher’s commitment, teachers’ style of teaching (let’s call it teaching methodology) and to a little extent ‘Pedagogy’.
  4. So how a person like me is going to get benefitted by this new knowledge?

My response

My response is as follows and believe me I do not interpret it as mischief and responding without any mischief in my mind. 

The short answer:

“No benefit. And one who sees no benefit should not waste effort, energy and money”.

Long answer: (be patient and read):

An understanding of nature of knowledge is central to an educator. Education is primarily concerned with acquisition, creation, critiquing, examining, and using knowledge. The questions of “what is knowledge?”, “How it is generated?”, “How is it examined?” etc. are of fundamental importance for an educator. One hardly needs to argue that knowledge is required in all human actions. Vatsyayana claims right in the beginning of his Nyaya-Bhashya:
“Successful activity (samartha-pravrtti) results when the object (artha) is cognised by the ‘instrument of valid knowledge’ (pramäna). Hence the instrument of valid knowledge is invariably connected with the object (arthavat).
There is no cognition (pratipatti) of object (artha) without the instrument of ‘Valid knowledge’; without cognition of object there is no successful activity. On being aware of the object with the help of the instrument of knowledge, the knower wants either to get it or avoid it. His specific effort (samiha), prompted by the desire of either getting or avoiding (the object), is called activity (pravrtti), whose success (samarthya), again, lies in its invariable connection with the result (phala).”

Plato in Theaetetus 201c–201d (Translation: Benjamin Jowett) claims:
“For true opinions, as long as they remain, are a fine thing and all they accomplish is good; but they are not willing to remain long, and they escape from a man’s mind, so that they are not worth much until one ties them down by an account (logon): and this, my friend, is recollection. When they are tied down, in the first place they become knowledge, and then they remain in place. That is why knowledge is more honourable and excellent than right opinion: because bound by reason.”
Before coming to this passage Plato (Socrates in the dialogue) is talking about uses of true opinion in achieving one’s ends. Vatsyayana is making the same point. Umpteen number of philosophers are making the same point again and again. In common day-to-day activities of life we use knowledge all the time. Even in making a cup of tea one uses knowledge of heat, how to control the source of heat, how long water needs to be boiled, how much tea leaves and sugar, and so on. The success of making good tea depends on all this knowledge.
Vatsyayana says true cognition or knowledge depends on pramans, Plato says it requires reasons. In day-to-day life we seek grounds for accepting any piece of information; even if it is as mundane as what is the market rate of wheat today. Enquiry about grounds is to assure ourselves that the information provided is reliable; it is asking pramanas or reasons. Thus, knowledge and reasons behind it are of utmost importance.
Now there are two questions: 1. Is there unanimity in matters of knowledge and acceptable reasons or pramanas or methos? And 2. Do I want to be autonomous in deciding matters of knowledge or want to live on borrowed knowledge? The first one is concerned with having at the least reasonable grounding in understanding knowledge; and the second one about my autonomy as a human being.
There are multiple systems of epistemology, the discipline which discusses knowledge. They all have strong agreements on some points and equally strong disagreements on some others. They give different definitions, criteria and methods of examination of knowledge, and persepctives. If a teacher knows about more than one such systems s/he is more likely to think critically and clearly; and also, to be able to help her/his students in the same.
Nyaya is an alternative way of looking at knowledge to the generally studied western epistemology. It has a particular penchant for clarity and precision, defining and then examining propositions. It has developed ways of elaborating arguments and communicating to others. These ideas and methos add to our understanding of knowledge and its ways, often provide criteria to critically examine concepts and claims made in the western epistemology, and provide substance to be examined through the ideas and methods of western epistemology. Thus, depend and broadens our perspective.
This should help one develop critical thinking, so much praised these days without really understanding what exactly it might be. The table below gives a tentative comparison between Nyaya’s ways of knowing and critical thinking, put forward more as an exercise in thinking than as a final conclusion. I do not have time to translate it into English, thus copying here in Hindi as it is:

One can go on and on on this issue. To the participants in this study I would say: better collect all the fliers posted as advertisements which duped you into this course to waste your money and time, and examine those numbered 1, 2 and 4. Also read again the introductory text given for the sah-adhyayan, right in the first session.
Can it help in, say, improving teaching methodology? Depends on (1) how well one understands Nyaya, (2) how well connected and consciously guided by theory his/her methodology is, (3) how conscious s/he is about having proper reasons for whatever she does in the classroom. To an activity cruncher and ready-made solution seeker it can give absolutely no help. To a conscious autonomous teacher it should. But, remember being autonomous is painful and dangerous.
Example 1: We all talk about leaving 2–5-year-old children much time for free exploration and play. Why do we recommend that? Common half understood answer is “children learn through play”. This is a mugged-up sentence which most of those who often repeat it cannot explain if one asks: what do they learn? How do you know? What is the use of what they learn? In western epistemology the idea of Knowledge by acquaintance gives one theoretical vocabulary and understanding of how sensory experience is basis of all knowledge and how it is connected with later development of skills and Propositional Knowledge. Similarly, understanding of Indriyas, their role in pratyaksha, the relationship between pratyaksha->sansakar->pramanas provides ability to articulate and think about those reasons. Which should help is choosing right kind of ‘free exploration’ for children at different stages of development. Aurobindo’s emphasis on sharpening sensory equipment for development of ideas and intelligence seems to come more or less directly from his understanding of indriyas and manas, and their role in knowledge formation.
Example 2: The understanding of anumana and difference between swartha and parartha anuman should directly help in spotting students’ difficulties in understanding as well as one’s articulation of explanation. But that we can understand when first we have studied anumana.
One can multiply these example with more detail and clarity, and we will do that in the course of this study as we progress. But at this stage, hardly having studied five concepts of Nyaya one should not attempt that.
But who can draw these benefits from studying Nyaya?
Anyone who puts in efforts and tries to understand. All efforts of using one’s mind and reason seriously even on completely unjustified and patently wrong disciplines will necessarily result in discipline of mind, rigorous use of logic, proper ways of reasoning and systematic thinking. I claim that serious and deep study of even astrology and palmistry will result in these “benefits of mind”, even if no “benefits of content”. However, many people do not understand the value of “benefits of mind”, one can see an example in Gandhi’s claim that study of geometry, astronomy, and geography helped him in nothing. (Hind Swaraj, chapter XVIII)
For whom will it be difficult to gain anything useful?
Let me begin by quoting Winch (last chapter in his Philosophy of Human Learning): “If one does not respect what one is to learn, or recognise the efforts that have gone into its creation and development, then success is unlikely.” Thus, attempts to study Nyaya (or anything) with a disdain for it will almost never result in good understanding of the subject and without good understanding its benefits will remain elusive. But “respect” here does not require an assumption of its truth or its benefits etc. in advance. All it requires is suspension of the judgment that “it is useless” or that “it is of great use” or that “I can understand whether X is useful without first knowing X”. Which means one has to enter with an open mind, with patience to draw a conclusion when one has learnt enough. A child who first wants to know the benefits of learning counting without knowing counting will never calculate even the area of his room.
Drawing benefits from study of Nyaya or anything written in Sanskrit centuries ago is very difficult without first studying it. Even its proper study is very difficult due to biases created by our education system. Anything written in Sanskrit is seen as archaic, or ponga-panthi or stone-age creation without knowing it. People will find tvak (त्वक्) as stone age without knowing that ‘touch’ comes from tvak or at the least has the same stone-age root. This disdain will strop proper and fair understanding, exactly as over-whelming respect or bhaktibhav will stop proper examination. Thus, entering into it with balanced open mind, open eyes and remanning patient till one has sufficient information to base one’s conclusions on is the key.
To re-emphasize the point: one cannot understand usefulness of a branch of knowledge without knowing what it happens to be. Yes, by asking others whom one believes or by asking a guru one can make an opinion about usefulness of anything. But that is more of an assurance at the best and indoctrination at the worst; not ‘understanding proper’. And that is why there is a contradiction between my “short answer” and “long answer”. Without knowing X, it is not possible to explain usefulness of X.
That is why the Sanskrit people had this concept of ‘Anubandh Chatushthay’ if you remember. They want to talk about the subject of a shatra, then relationship of the book wirth that Shastra, then prayojan of it’s study and then of being Adhikari. That may motivate people to study it. If one does not see prayojan one will find no inclination to study it. So, think if you have a prayojana which may be helped by this.



Truth and True

July 25, 2022

Rohit Dhankar

A friend on FB (Sachin) tagged me, among others, to a post, in which he posed the following two questions:

“This says that “Truth” and “True” not the same. Then other questions coming to my mind,

1. How do you differentiate Truth/True from “Reality” and “Fact”?

2. When we discuss JTB Account in Epistemology, what do we refer to: “Truth” or “True”.”

It refers to the following picture:

Pic 1                                                                                                                                                          

First let’s take Sachin’s questions:

He mentions four concepts “Truth”, “True”, “Reality”, and “Fact”.

The Context

Our concepts and language functions in a context. By context here I mean the background ideas, assumptions, beliefs and so on. The four concepts mentioned by Sachin here require a background to understand, discuss and talk about.

We have to necessarily imagine a “mind”, which is thinking about these concepts. These concepts are part of the content of that mind. We cannot deny the existence of at the least one mind, that is our own. Which means at the least one mind which is asking this question ‘exists’.

Let’s be a little graceful and without any justification grant ‘existence’ to other minds with whom we are in conversation. As far as we know there are about 6 billion more wandering about this earth, with whom we can potentially be in conversation.

Pic 2: This shows us

Reality:

The first question we can ask in this context is: are these minds ‘real’, that is do they ‘actually exist’? We assume or believe they do. This is one part of reality. But these minds have ideas, thoughts, images, and so on as their contents. What these ideas are about? What these images are of? Is there anything ‘outside’ these minds? Existing independently of them? Most people believe ‘yes’.

The central meaning of reality is ‘the state of the world as it is’. The totality of all existence. Some people believe that ‘yes, there is a world outside our minds, but we do not know it as it is’. That is, the picture of this world we make in our minds does not exactly match with it as it exists, but is mediated, formed, by our minds. In this sense the reality is the totality of existence ‘as it appears to us’. These two are varieties of reality about actual existence outside our minds.

Pic 3: we are within this somewhere

But there can also be a reality1 that we construct in our minds. For example, Euclid geometry can be seen as a reality constructed through axioms, postulates, definitions, and proven theorems. There is nothing of this which we can call material outside our minds which we experience. All of it is inside our minds but still something of this is independent of our minds. “Independent” here only means ‘which we cannot imagine as we please, it has its own rules’. For example,

If A=B, and B=C, then A=C.

You can deny the italic underlined part of this (A=B, and B=C), but if you do accept it, then the bold part (A=C) can not be denied.

Reality: 1. “The state of the world as it is”.  2. “The state of the world as it appears to us”.

Reality1: Coherent axiomatic system we construct in our minds.

Fact:

A part of reality under our consideration or focus, as it is. As it actually is.

Pic 4

[The picture is from Epistemology: the theory of knowledge by Daniel Cardinal, Jeremy Hayward,
Gerald Jones]

True:

Let’s consider a statement: “There is a tree in front of my house”. We say this statement is ‘true’ when there is actually a tree in front of my house; if there is none, we say it is ‘false’. We designate a statement true or false. Thus, the term “true” is used to express epistemic status or appraisal of a statement. In other words, ‘true’ expresses is epistemic status of a statement.

Truth:

Property of the content of a statement. Property of a proposition. When the claim made through a statement matches with reality we say, ‘it expresses the truth’. Otherwise, we say ‘what it expresses is not a truth’. The nature of truth in Reality (refer above) and Reality1 differs. This is complicated and admits varieties depending on what is being discussed. In the above proposition (There is a tree in front of my house) it refers to the world outside my mind, for realists, at the least. But there can also be mathematical truths, which refer to axiomatic systems. Truth is that which a true proposition indicates.

The Picture

As far as my understanding goes this picture can be used to make some points with discussion.

However, in itself it is somewhat misleading. What is called TRUTH (C) in the picture I would call ‘fact’ or ‘part’ of reality. A and B are two different perceptions from two different stand points. The issue of true and truth arises only when these two perceptions are articulated in language, through statements. Before that they are just perceptions, from two stand points. Neither true, not false.

Pic 5

Roughly speaking the two corresponding statements could be:

A: “It is rectangular”.

B: “It is circular”.

Where “It” refers to the object C, that is a cylinder.

Recall, the term ‘true’ we use to designate an epistemic status to a statement. Both statements A and B are false. As a cylinder is a three-dimensional object, while a rectangle and a circle are two dimensional. Therefore, they do not match with the reality.

These statements can be modified as below:

A1: From my standpoint it appears to be rectangular.

B1: From my standpoint it appears to be circular.

Now both statements are true. Because what they express corresponds (matches) with the reality as it appears. Notice, now the issue is ‘matching with the perception’ and not with the reality itself. 

One may go further. As one can argue that:

P1: The object appears rectangular from one standpoint. and

P2: Appears circular from another standpoint forming exact right angle (between the lines of sight from both standpoints).

P3: Only a cylindrical object can fulfill both conditions P1 and P2.

Therefore, P4: This object is a cylinder.

Now, P4 is true, what it expresses is the truth. Because it matches with the reality.
