The Nyāya Śāstra, one of the six orthodox schools of Indian philosophy, presents a comprehensive metaphysical framework through its theory of seven categories (padārthas). According to the foundational text, these are enumerated as "dravyaguṇakarmasāmānyaviśeṣasamavayābhāvāḥ sapta padārthāḥ" (substance, quality, action, universal, particular, inherence, and non-existence are the seven categories). These seven categories can be fundamentally divided into two types: bhāva padārtha (positive entities that exist) and abhāva padārtha (negative entities representing non-existence). While the first six categories—substance (dravya), quality (guṇa), action (karma), universal (sāmānya), particular (viśeṣa), and inherence (samavāya)—constitute positive existence, abhāva stands uniquely as the category of non-existence or absence.

The Nature of Abhāva

The Nature of Abhāva

Abhāva is invariably expressed through negative linguistic constructions. When we state "there is no water in the pot" (ghaṭe jalam nāsti), we cognize the absence of water (jalābhāva). This linguistic formulation reveals a crucial philosophical insight: every instance of abhāva necessarily involves a pratiyogī, which refers to the entity whose non-existence is being asserted. In the aforementioned example, water serves as the pratiyogī of the absence being cognized.

The Four-Fold Classification of Abhāva

The Four-Fold Classification of Abhāva

=== 1. Prāgabhāva (Prior Non-Existence) ===

=== Prāgabhāva (Prior Non-Existence) ===

Prāgabhāva represents the state of non-existence that precedes the creation or manifestation of an entity. This temporal absence can be illustrated through a practical example: when seeds are planted in a garden, there exists a period before the emergence of seedlings during which the plant does not exist. This absence of the plant (aṅkurābhāva) from the time of planting until germination constitutes aṅkuraprāgabhāva. The philosophical significance lies in our ability to perceive and cognize this absence before the entity comes into being.

=== 2. Pradhvaṃsābhāva (Posterior Non-Existence) ===

=== Pradhvaṃsābhāva (Posterior Non-Existence) ===

Pradhvaṃsābhāva, derived from pradhvaṃsa (destruction), represents the non-existence that follows the destruction or cessation of an entity. Continuing with our botanical example, when the plant dies due to inadequate water supply, we cognize the absence of the plant that once existed. This post-destruction absence, expressed through negative formulations, constitutes pradhvaṃsābhāva or simply dhvaṃsa.

=== 3. Atyantābhāva (Absolute Non-Existence) ===

=== Atyantābhāva (Absolute Non-Existence) ===

Atyantābhāva presents the most philosophically complex category, characterized as eternal (nitya) and permanent. When we assert "there is no flower in the tree," the absence cognized through this negative statement represents atyantābhāva. However, this raises a legitimate philosophical question: how does atyantābhāva differ from prāgabhāva and pradhvaṃsābhāva?

However, this raises a legitimate philosophical question: how does atyantābhāva differ from prāgabhāva and pradhvaṃsābhāva?

Contemporary Ācāryas offer nuanced interpretations. Some maintain that atyantābhāva occurs in locations where the pratiyogī cannot possibly reside. For instance, the statement "there is no color in air" (vāyau rūpam nāsti) expresses the absence of color, where color serves as the pratiyogī. Since color cannot exist in air under any temporal conditions, neither prāgabhāva nor pradhvaṃsābhāva of color can occur in air. Therefore, this absence constitutes rūpātyantābhāva.

Alternative scholarly interpretations suggest that while atyantābhāva is eternal in nature, it becomes epistemologically accessible only in conjunction with the prāgabhāva or pradhvaṃsābhāva of its pratiyogī, thus maintaining its distinctiveness from other forms of non-existence.

=== 4. Anyonyābhāva (Mutual Non-Existence) ===

=== Anyonyābhāva (Mutual Non-Existence) ===

Anyonyābhāva represents difference or distinctiveness between entities. The statement "a boy is not a girl" exemplifies this category, where the negative particle 'not' expresses anyonyābhāva. Here, the girl serves as the pratiyogī, and the absence cognized is essentially bheda (difference). This form of abhāva captures the logical relationship of non-identity between distinct entities.
