Four Kinds of Absence

Tarka Sangraha, Uddesha 8

अभावश्चतुर्विधः- प्रागभावः, प्रध्वंसाभावः, अत्यन्ताभावः, अन्योन्याभावश्चेति ॥

Meaning · English

Absence is of four kinds: absence before something comes to be, absence after it is destroyed, absence for all time, and absence of one thing being another.

After listing what exists, Nyaya asks a further question: is a missing thing nothing at all? The school says no. Absence is a real, knowable category, called abhava, and it comes in four kinds. Pragabhava is the absence before: a pot does not yet exist in the lump of clay. Pradhvamsabhava is the absence after: the pot, once smashed, is gone. Atyantabhava is absence across all time: there is no colour in the wind, never was and never will be. Anyonyabhava is mutual absence: a pot is not a cloth, and the difference is itself a fact. Annambhatta's own commentary notes only that this verse divides absence into its kinds. The reasoning behind it is simple. We say truthfully 'there is no pot here', and a true statement needs something real to be true of. So absence has to be counted, and sorted by how it is missing.

Think of an empty parking space. Before the car arrives, the space is empty in one way. After it drives off, it is empty in another. The wall behind it never held a car at all. And the space is not the neighbouring space. Each 'nothing' is a different, checkable fact, which is what the four absences name.

Modern logic and philosophy still treat absence seriously. Negative facts are a live debate: Bertrand Russell argued that the world needs them to make 'there are no unicorns' true, while others try to do without them. Everyday reasoning relies on absences constantly, as when a doctor notes the lack of a symptom. Nyaya's fourfold split roughly matches distinctions in tense and time (not yet, no longer, never) plus the difference between two things (non-identity). Formal logic expresses these with negation and quantifiers rather than as four kinds of entity. Whether absences are real things or just ways of speaking remains open, and many philosophers prefer the second view.
