The epistemology of Vaiśeṣika school of Hinduism accepted only two reliable means to knowledge - perception and inference.[2]

Vaisheshika espouses a form of atomism, that the reality is composed of four substances (earth, water, air, fire). Each of these four are of two types, explains Ganeri,[5] atomic (paramāṇu) and composite. An atom is that which is indestructible (anitya), indivisible, and has a special kind of dimension, called “small” (aṇu). A composite is that which is divisible into atoms. Whatever human beings perceive is composite, and even the smallest perceptible thing, namely, a fleck of dust, has parts, which are therefore invisible.[5] The Vaiśeṣikas visualized the smallest composite thing as a “triad” (tryaṇuka) with three parts, each part with a “dyad” (dyaṇuka). Vaiśeṣikas believed that a dyad has two parts, each of which is an atom. Size, form, truths and everything that human beings experience as a whole is a function of atoms, their number and their spatial arrangements.

The earliest systematic exposition of the Vaisheshika is found in the Vaiśeṣika Sūtra of Kaṇāda (or Kaṇabhaksha). This treatise is divided into ten books. The two commentaries on the Vaiśeṣika Sūtra, Rāvaṇabhāṣya and Bhāradvājavṛtti are no more extant. Praśastapāda’s Padārthadharmasaṁgraha (c. 4th century) is the next important work of this school. Though commonly known as bhāṣya of Vaiśeṣika Sūtra, this treatise is basically an independent work on the subject. The next Vaisheshika treatise, Candra’s Daśapadārthaśāstra (648) based on Praśastapāda’s treatise is available only in Chinese translation. The earliest commentary available on Praśastapāda’s treatise is Vyomaśiva’s Vyomavatī (8th century). The other three commentaries are Śridhara’s Nyāyakandalī (991), Udayana’s Kiranāvali (10th century) and Śrivatsa’s Līlāvatī (11th century). Śivāditya’s Saptapadārthī which also belongs to the same period, presents the Nyāya and the Vaiśeṣika principles as a part of one whole. Śaṁkara Miśra’s Upaskāra on Vaiśeṣika Sūtra is also an important work.[22]

The Categories or Padārtha[edit]

== The Categories or Padārtha ==

According to the Vaisheshika school, all things which exist, which can be cognised, and which can be named are padārthas (literal meaning: the meaning of a word), the objects of experience. All objects of experience can be classified into six categories, dravya (substance), guṇa (quality), karma (activity), sāmānya (generality), viśeṣa (particularity) and samavāya (inherence). Later Vaiśeṣikas (Śrīdhara and Udayana and Śivāditya) added one more category abhava (non-existence). The first three categories are defined as artha (which can perceived) and they have real objective existence. The last three categories are defined as budhyapekṣam (product of intellectual discrimination) and they are logical categories.[23]

The atomic theory[edit]

According to the Vaiśeṣika school, the trasareṇu are the smallest mahat (perceivable) particles and defined as tryaṇukas (triads). These are made of three parts, each of which are defined as dvyaṇuka (dyad). The dvyaṇukas are conceived as made of two parts, each of which are defined as paramāṇu (atom). The paramāṇus (atoms) are indivisible and eternal, they can neither be created nor destroyed.[30] Each paramāṇu (atom) possesses its own distinct viśeṣa (individuality).[31]
