Anekantavada

 
The second main principle of Jainism is anekāntavāda,[76][77] from anekānta ("many-sidedness") and vada ("doctrine").[76][77]  The doctrine states that truth and reality are complex and always have multiple aspects.  It further states that reality can be experienced, but cannot be fully expressed with language. It suggests that human attempts to communicate are Naya, "partial expression of the truth".[76] According to it, one can experience the taste of truth, but cannot fully express that taste through language.  It holds that attempts to express experience are syāt, or valid "in some respect", but remain "perhaps, just one perspective, incomplete".[78]

Syādvāda is a theory of qualified predication, states Koller. It states that all knowledge claims must be qualified in many ways, because reality is many-sided.[4] It is done so systematically in later Jain texts through saptibhaṅgīnaya or "the theory of sevenfold scheme".[4] These saptibhaṅgī seem to have been first formulated in Jainism by the 5th or 6th century CE Svetambara scholar Mallavadin,[31] and they are:[30][32][33]

  1. Affirmation: syād-asti—in some ways, it is,
  2. Denial: syān-nāsti—in some ways, it is not,
  3. Joint but successive affirmation and denial: 
        syād-asti-nāsti—
        in some ways, it is, and it is not,
  4. Joint and simultaneous affirmation and denial: 
        syāt-asti-avaktavyaḥ—
        in some ways, it is, and it is indescribable,
  5. Joint and simultaneous affirmation and denial: 
        syān-nāsti-avaktavyaḥ—
        in some ways, it is not, and it is indescribable,
  6. Joint and simultaneous affirmation and denial: 
        syād-asti-nāsti-avaktavyaḥ—
        in some ways, it is, it is not, and it is indescribable,
  7. Joint and simultaneous affirmation and denial: 
        syād-avaktavyaḥ—
        in some ways, it is indescribable.

The Saptabhangivada, the seven predicate theory may be summarized as follows:[4]

The seven predicate theory consists in the use of seven claims about sentences, each preceded by "arguably" or "conditionally" (syat), concerning a single object and its particular properties, composed of assertions and denials, either simultaneously or successively, and without contradiction. These seven claims are the following.

  1. Arguably, it (that is, some object) exists (syad asty eva).
  2. Arguably, it does not exist (syan nasty eva).
  3. Arguably, it exists; arguably, it doesn't exist (syad asty eva syan nasty eva).
  4. Arguably, it is non-assertible (syad avaktavyam eva).
  5. Arguably, it exists; arguably, it is non-assertible (syad asty eva syad avaktavyam eva).
  6. Arguably, it doesn't exist; arguably, it is non-assertible (syan nasty eva syad avaktavyam eva).
  7. Arguably, it exists; arguably, it doesn't exist; arguably it is non-assertible (syad asty eva syan nasty eva syad avaktavyam eva).

There are three basic truth values, namely, true (t), false (f) and unassertible (u).
