[[File:उमास्वामी आचार्यजी.jpg|thumb|Umaswati (2nd century AD), author of first Jain work in Sanskrit, [[Tattvartha Sutra|Tattvārthasūtra]], expounding the [[Jain philosophy]] in a most systematized form acceptable to all sects of Jainism.]]
[[Jainism|Jains]] made its own unique contribution to this mainstream development of logic by also occupying itself with the basic epistemological issues, namely, with those concerning the nature of knowledge, how knowledge is derived, and in what way knowledge can be said to be reliable.

The Jains have doctrines of [[Relativism|relativity]] used for logic and reasoning:

* [[Anekantavada|Anekāntavāda]] – the theory of relative pluralism or manifoldness;
* [[Syadvada|Syādvāda]] – the theory of conditioned predication and;
* [[Anekantavada#Nayav%C4%81da|Nayavāda]] – The theory of partial standpoints.

These concepts in [[Jain philosophy]] made important contributions to the thought, especially in the areas of skepticism and relativity.
