The Cognitive Process and some characteristics of Citta

It has been said that buddhi and the internal objects have evolved in order to giving scope to the experience of the purusha. What is the process of this experience? Read more

Philosophy in the Nyaya sutras

The Nyaya sutras begin with an enumeration of the sixteen subjects, viz. means of right knowledge (pramana), object of right knowledge (prameya), doubt (samshaya), purpose (prayojana), illustrative instances (drishtanta), accepted conclusions (siddhanta), premisses (avayava), argumentation (tarka), ascertainment (nirnaya), debates (vada), disputations (jalpa), destructive criticisms (vitanda), fallacy (hetvabhasa), quibble (chala), refutations (jati), points of opponent’s defeat (nigrahasthana), and hold that by a thorough knowledge of these the highest good (nihshreyasa), is attained. In the second sutra it is said that salvation (apavarga) is attained by the successive disappearance of false knowledge (mithyajnana), defects (dosha), endeavours (pravritti, birth (janma), and ultimately of sorrow (1).

The Origin of Knowledge (Pramana)

The manner in which knowledge originates is one of the most favourite topics of discussion in Indian philosophy. We have already seen that Samkhya-Yoga explained it by supposing that the buddhi (place of consciousness) assumed the form of the object of perception, and that the buddhi so transformed was then intelligized by the reflection of the pure intelligence or purusha. The Jains regarded the origin of any knowledge as being due to a withdrawal of a veil of karma which was covering the all-intelligence of the self. Read more

The four Pramanas of Nyaya

We know that the Carvakas admitted perception (pratyaksha) alone as the valid source of knowledge. Read more

Nyaya Perception (Pratyaksha)

The naiyayikas admitted only the five cognitive senses which they believed to be composed of one or other of the five elements. These senses could each come in contact with the special characteristic of that element of which they were composed. Thus the ear could perceive sound, because sound was the attribute of akasha, of which the auditory sense, the ear, was made up. The eye could send forth rays to receive the colour, etc., of things. Thus the cognitive senses can only manifest their specific objects by going over to them and thereby coming in contact with them. The cognitive senses (vak, pani, pada, payu, and upastha) recognized in Samkhya as separate senses are not recognized here as such for the functions of these so-called senses are discharged by the general motor functions of the body.

Nyaya two classes of perception

I have pointed out above that Nyaya divided perception into two classes as nirvikalpa (indeterminate) and savikalpa (determinate) according as it is an earlier or a later stage. Vacaspati says, that at the first stage perception reveals an object as a particular; the perception of an orange at this avikalpika or nirvikalpika stage gives us indeed all its colour, form, and also the universal of orangeness associated with it, but it does not reveal it in a subject-predicate relation as when I say “this is an orange.” Read more

Nyaya Inference

Inference (anumana) is the second means of proof (pramana) and the most valuable contribution that Nyaya has made on this subject. It consists in making an assertion about a thing on the strength of the mark or linga which is associated with it, as when finding smoke rising from a hill we remember that since smoke cannot be without fire, there must also be fire in yonder hill. In an example like this smoke is technically called linga, or hetu. Read more

Upamana and Shabda

The third pramana, which is admitted by Nyaya and not by Vaisheshika, is upamana, and consists in associating a thing unknown before with its name by virtue of its similarity with some other known thing. Thus a man of the city who has never seen a wild ox (gavaya) goes to the forest, asks a forester – “what is gavaya?” and the forester replies – “oh, you do not know it, it is just like a cow”; after hearing this from the forester he travels on, and on seeing a gavaya and finding it to be similar to a cow he forms the opinion that this is a gavaya. This knowing an hitherto unknown thing by virtue of its similarity to a known thing is called upamana. Read more

The doctrine of Soul

Dhurtta Carvakas denied the existence of soul and regarded consciousness and life as products of bodily changes; there were other Carvakas called Sushikshita Carvakas who admitted the existence of soul but thought that it was destroyed at death. Read more

The Paratah-pramanya doctrine of Nyaya and the Svatah-pramanya doctrine of Mimamsa

The doctrine of the self-validity of knowledge (svatah-pramanya) forms the cornerstone on which the whole structure of the Mimamsa philosophy is based. Validity means the certitude of truth. The Mimamsa philosophy asserts that all knowledge excepting the action of remembering (smriti) or memory is valid in itself, for it itself certifies its own truth, and neither depends on any other extraneous condition nor on any other knowledge for its validity. Read more

Indeterminate and determinate perception

There are two kinds of perception in two stages, the first stage is called nirvikalpa (indeterminate) and the second savikalpa (determinate). The nirvikalpa perception of a thing is its perception at the first moment of the association of the senses and their objects. Read more

The nature of knowledge

All knowledge involves the knower, the known object, and the knowledge at the same identical moment. All knowledge whether perceptual, inferential or of any other kind must necessarily reveal the self or the knower directly. Thus as in all knowledge the self is directly and immediately perceived, all knowledge may be regarded as perception from the point of view of self. Read more

The Psychology of Illusion

The question however arises that if all apprehensions are valid, how are we to account for illusory perceptions which cannot be regarded as valid? The problem of illusory perception and its psychology is a very favourite topic of discussion in Indian philosophy. Read more

Upamana, Arthapatti

Analogy (upamana) is accepted by Mimamsa in a sense which is different from that in which Nyaya took it. The man who has seen a cow (go) goes to the forest and sees a wild ox (gavaya), and apprehends the similarity of the gavaya with the go, and then cognizes the similarity of the go (which is not within the limits of his perception then) with the gavaya. Read more

The Pramana of Non-perception (anupalabdhi)

In addition to the above pramanas Kumarila admits a fifth kind of pramana, viz. anupalabdhi for the perception of the non-existence of a thing. Kumarila argues that the non-existence of a thing (e.g. there is no jug in this room) cannot be perceived by the senses, for there is nothing with which the senses could come into contact in order to perceive the non-existence.

In what sense is the world-appearance false?

The world is said to be false – a mere product of maya. The falsehood of this world-appearance has been explained as involved in the category of the indefinite which is neither sat “is” nor asat “is not.” Here the opposition of the “is” and “is not” is solved by the category of time. The world-appearance is “is not,” since it does not continue to manifest itself in all times, and has its manifestation up to the moment that the right knowledge dawns. It is not therefore “is not” in the sense that a “castle in the air” or a hare’s horn is “is not,” for these are called tuccha, the absolutely non-existent. Read more

The nature of the world-appearance, phenomena

The world-appearance is not however so illusory as the perception of silver in the conch-shell, for the latter type of worldly illusions is called pratibhasika, as they are contradicted by other later experiences, whereas the illusion of world-appearance is never contradicted in this worldly stage and is thus called vyavaharika (from vyavahara, practice, i.e. that on which is based all our practical movements). Read more

The Definition of Ajnana – nescience

Ajnana the cause of all illusions is defined as that which is beginningless, yet positive and removable by knowledge (anadibhavarupatve sati jnananivartyatvam). Though it manifests itself in all ordinary things (veiled by it before they become objects of perception) which have a beginning in time, yet it itself has no beginning, for it is associated with the pure consciousness which is beginningless. Read more

Ajnana established by Perception and Inference

Ajnana defined as the indefinite which is neither positive nor negative is also directly experienced by us in such perceptions as “I do not know, or I do not know myself or anybody else,” or “I do not know what you say,” or more particularly “I had been sleeping so long happily and did not know anything.” Read more

Anirvacyavada and the Vedanta Dialectic

We have already seen that the indefinite ajnana could be experienced in direct perception and according to Vedanta there are only two categories. The category of the real, the self-luminous Brahman, and the category of the indefinite. The latter has for its ground the world-appearance, and is the principle by which the one unchangeable Brahman is falsely manifested in all the diversity of the manifold world. Read more

Vedanta theory of Perception and Inference

Pramana is the means that leads to right knowledge. If memory is intended to be excluded from the definition then pramana is to be defined as the means that leads to such right knowledge as has not already been acquired. Right knowledge (prama) in Vedanta is the knowledge of an object which has not been found contradicted (abadhitarthavishayajnanatva). Except when specially expressed otherwise, prama is generally considered as being excludent of memory and applies to previously unacquired (anadhigata) and uncontradicted knowledge (1). Read more

Pleasure and pain

The inner experiences of pleasure and pain also are generated by a false identification of antahkarana transformations as pleasure or pain with the self, by virtue of which are generated the perceptions, “I am happy,” or “I am sorry.” Read more

Vedanta Theory of Illusion

We have already seen that the Mimamsists had asserted that all knowledge was true simply because it was knowledge (yatharthah sarve vivadaspadibhutah pratyayah pratyayatvat). Even illusions were explained by them as being non-perception of the distinction between the thing perceived (e.g. the conch-shell), and the thing remembered (e.g. silver). Read more

Examination of mental processes

It is only by the mind that the teachings we are now giving you may be grasped and understood, and used to your advantage and benefit. We are talking direct to your mind now, and are making appeals to it, that it may be interested and may open itself to what is ready to come into it from its own higher regions. We are appealing to the Intellect to direct its attention to this great matter, that it may interpose less resistance to the truths that are waiting to be projected from the Spiritual Mind, which knows the Truth.
