摘要
The Jain logic （Nay） addresses concerns elicited by sense experience of observable and measurable reality. Reality is what it is, and it exists independent of the observer. The last Jain Tirthankar Mahaveer suggested that organisms interact with such realities for survival needs and become concerned about the consequences. He suggested a code of conduct for reality-based behaviors to address concerns. Perceptions and impressions provide measures （praman） of information in sense experience, and with other evidence guide choices and decisions to act and bear consequences. Ethical behaviors rooted in reality have desirable consequences, and inconsistent and contradictory behaviors are undesirable consequences. Omniscience （God, Brahm） is discarded as a self-referential ad hoc construct inconsistent and contradictory to real world behaviors. This article is survey of assumptions and models to represent, interpret, and validate knowledge that begins with logical deduction for inference （anuman） based on evidence from sense experience （Jain 2011）. Secular and atheistic thrust of thought and practice encourages reasoning and open-ended search with affirmed assertions and independent evidence. Individual identity （atm） emerges with consistent behaviors to overcome fallibility and unreliability by minimizing doubt （Syad-Saptbhangi Nay）. The first Tirthankar Rishabh Nath （ca. 2700 BC） suggested that the content （sat） of real and abstract objects and concerns during a change is conserved as the net balance of the inputs and outputs （Tatia 1994）. Identity and content of assertions and evidence is also conserved during logical manipulations for reasoning. Each assertion and its negation are to be affirmed with independent evidence, and lack of evidence for presence is not necessarily the evidence for either non-absence or non-existence.
