Avidyā-tattva-dīpikā: Seventy-six

In Advaita philosophy, 'visibility' (dṛśyatva) or 'being an object of perception' is presented as a central proof for establishing the falsity of the world: "The world is visible, therefore it is false." However, opponents raise two major objections against this argument, which weaken the logical foundation of this inference.

First: The Unestablished Nature of the Reason (Asiddhatva of the Hetu)

Advaitins claim that visibility is an irrefutable proof of falsity. But this claim is immediately challenged, because the very definition of 'visibility' is contested. Generally, visibility means that which can become the object of knowledge or experience—that which is known. But opponents question: how do we know the world? If 'knowing' means being apprehended through mental modifications or changes (vṛtti), then this knowledge does not automatically prove the world false.

If visibility is understood as 'knowability,' then the Self too could be visible in one sense, because we also think about or discuss the Self. But according to Advaita, the Self is absolute reality. Then, if the Self is also visible in some sense and is real, how can visibility be certain proof of falsity? Due to this contradiction, visibility itself becomes an unestablished reason. The definitional ambiguity of the reason and questions about its universal application reveal weakness at the very first step of the inference.

Second: The Indeterminacy of the Reason (Anaikāntika / Savyabhicāra)

Even if we accept that visibility can somehow be granted, it still becomes 'indeterminate' or 'inconclusive' (Anaikāntika) for proving falsity. For the validity of inference, 'invariable concomitance' (Vyāpti) is essential—that is, there must be an inseparable relationship between the reason (visibility) and what is to be proved (falsity). This relationship must be such that wherever visibility exists, falsity must inevitably be present. In other words, "whatever is seen is always false."

The term 'savyabhicārī' is an important logical terminology in Indian logic, generally used to denote a flaw in the 'reason' or cause. According to its formation, "sa" means "with" or "accompanied," and "vyabhicāra" means "deviation" or "irregularity." Thus "savyabhicārī" means something that is not uniformly applicable everywhere, sometimes matching and sometimes not. Simply put, that cause or reason which sometimes connects with the effect or goal, and sometimes becomes disconnected, is savyabhicārī.

Philosophically, a savyabhicārī reason is that cause which is not inseparably related to what is to be proved. Inference or reasoning is valid only when its reason remains connected with what is to be proved everywhere, with no exceptions. But in the case of a savyabhicārī reason, this connection or concomitance is broken, because the reason sometimes indicates the goal and sometimes does not. Consequently, the reasoning becomes invalid, because its foundation is unstable.

For example, if someone says, "Where there is smoke, there is fire"—here fire is the reason and smoke is what is to be proved. Generally, when smoke is seen on a mountain, we understand there is fire, but fire does not always produce only smoke; smoke appears in cases of incense, mist, or dust as well, where the establishing cause—fire—is not present. Like when a distant field appears somehow smoky. Here there is no fire in the field, but there is dust or mist or both. Therefore, "for smoke, fire must be present"—this reason is not true everywhere; it is sometimes true, sometimes false. Hence this reason is savyabhicārī.

For this reason, Nyāya philosophy states that valid inference requires an "invariable reason"—a cause that remains connected with what is to be proved everywhere. A savyabhicārī reason is not acceptable in logic, because it destroys the reliability of proof. Thus the term "savyabhicārī" in logic refers to that unstable and exceptional cause which sometimes indicates the result but not always, and is therefore unsuitable for establishing truth.

Opponents directly challenge this concomitance by giving examples where visibility exists but falsity does not. The prime example of this is the Self (Ātman).

Visibility and Reality in the Case of the Self: According to Advaita, the Self is self-luminous (svaprakāśa)—it illuminates itself, requiring no other knowledge or light. However, critics argue that the Self too can become an object of knowledge through mental modifications or thought (vṛtti). That is, in some sense, 'visibility' applies to the Self as well. When we think about the Self, it becomes a kind of object of mental knowledge. But according to Advaita, the Self is absolute reality; it is never false. Therefore, here there is 'visibility' (since the Self is an object of thought), but no 'falsity' (since the Self is real). This is an extreme violation of concomitance.

This example proves that even when visibility is present, falsity may not be. Therefore, the reason of 'visibility' does not inevitably point to falsity—that is, it is indeterminate.

Other Counter-examples:

Opponents further mention that some things remain true despite being visible, such as reflections (pratibimba) of the Self or Brahman. A reflected image is visible, but the original object is real. Again, some things can be false even while being invisible. For example, erroneous knowledge like shell-silver appears invisibly (in the mental realm), which is not visible yet is false.

Therefore, "visibility" can never be a determining sign of falsity. A reason is strong only when it has no exceptions. But because of exceptions like the Self—which is absolute reality—visibility cannot be accepted as the sole or inseparable proof of falsity.

Consequently, the Advaitic inference based on 'visibility' becomes logically weak. On one hand, its reason 'visibility' is itself unestablished or controversial, because there are questions about its definition and universal application. On the other hand, its concomitance or connection is indeterminate, because counter-examples exist (like the Self) where visibility is present but falsity is not.

This shows that the apparently simple argument "The world is visible, therefore false" actually collapses within itself, because what is used to prove (visibility) loses the capacity to prove. This analysis reveals a deep philosophical weakness in the Advaitic inference and demonstrates the strength of the opponents' reasoning.

Advaita Vedanta is a philosophical system founded upon a two-level conception of reality—the Absolute (Pāramārthika) and the Practical (Vyāvahārika). At the absolute level, only Brahman is real, beyond illustration and inviolable; at the practical level, the world is apparently real, changeable, and eliminable through knowledge. This two-level framework allows Advaita to declare the falsity of the world while still acknowledging the efficacy of experience.

The fundamental definition of Falsity (Mithyātva) is indefinability (Anirvacanīyatva)—the world is neither real nor unreal, but different from both existence and non-existence. However, various logical objections arise around this concept—lack of locus, fallacy of changing the subject, qualification by the unestablished, proving the already proven, and the indeterminacy of visibility—which challenge the foundation of the falsity-inference.

In response to these objections, Advaita adopts concepts of Practical Reality (Vyāvahārika Sattva) and Multiple Ignorance Theory (Nānā Ajnāna Pakṣa), maintaining logical consistency while removing the fear of losing non-dualism. Yet ultimate truth is not logic but what is revealed by Scripture (Śruti).

The term 'revealed' comes from the word "pratyakṣa," which literally means "present before the senses" or "directly apprehended." "Prati" means "in front of" or "directly," and "akṣa" means "sense organ," especially the eye. Thus "pratyakṣa" means what is known by being present before the senses, and "pratyakṣita" means that object or event which has been directly seen, heard, or experienced.

Simply put, pratyakṣita means "what is known through direct perception"—that is, what we see with our own eyes, hear with our ears, feel through touch, or directly experience through other senses. This is knowledge that arises from direct experience without the mediation of inference, comparison, or reasoning.

For example, "I witnessed the sunrise"—here the sunrise is a perceived object, because it was seen with the eyes. Again, "I felt the heat of fire"—here heat too is perceived, because it was known directly through the sense of touch. Similarly, all the things we see, hear, or experience daily constitute the perceived world or perceived objects.

From philosophy's perspective, perception is a primary means of knowledge (Pramāṇa) in Indian epistemology. That is, it is the method through which true knowledge can be obtained. Therefore, pratyakṣita means those objects, events, or states which have been directly known through sensory contact. In brief, pratyakṣita means "directly seen or experienced," "experienced through the senses," or "obtained through immediate knowledge"—what appears authentically in one's own experience.

Advaita is a refined idealism where Brahman is the sole ultimate reality, and the world is a maya-born appearance that is sublated the moment Brahman-knowledge arises.

The question of reality and proof has always occupied the central focus of subtle, sharp, and deep inquiry in philosophy—understanding the nature of reality and analyzing the limits and powers of valid means of knowledge (Pramāṇa) for obtaining knowledge. Specifically, the ontological difference between these two—the "world (Prapañcaḥ)" and the "Self (Ātman)"—and what kind of proof can establish truth in each case is very important here. Through this, we can enter an inner level of Indian philosophical thought where knowledge, being, and maya are intricately intertwined.

First, let me explain a few key terms:
Pakṣa means that which is being reasoned about—here it is the world (prapañca).
Sādhya means what is to be proved—here it is "being the object of truth-revealing proof" or ultimate provability (tāttvika-prameyatva); that is, such an object which, when proved, reveals its ultimate true nature (tattva).
Hetu means the reason of the argument—here it is dharmitvā, meaning "the capacity to possess qualities or properties."
Dṛṣṭānta means example—here the speaker brings the Self (ātman), which is taken as the object or subject of ultimate truth.

Now let us see how the reasoning is structured:

Statement (pratijñā): The speaker says—"The world is the object of truth-revealing proof." That is, the world is such an object which, if known through inference, verbal testimony, or other proofs, can reveal its actual or ultimate form to us. In this way, the speaker wants to show—the world can be provable not merely in a practical (vyāvahārika) sense, but also in discussions of ultimate or absolute truth.

Reason (hetu): Then he says—"dharmitvāt," meaning "because the world is the locus of qualities." The world contains color, shape, motion, weight, heat—all these qualities exist. The form of a pot, the solidity of wood, the burning capacity of fire—all exist within the world. Where there are qualities, there must certainly be some "bearer" or "locus" (ādhāra), which is called dharmi. This capacity to bear qualities is, in the speaker's view, the cause of provability—that object which contains dharma can reveal truth when proof (pramāṇa) is applied to it.
