The Jaina metaphysics is a realistic and relativistic pluralism. It is called Anektavad or The Doctrine of Manyness of Reality. Jaina holds that there are innumerable material atoms and innumerable individual souls (spirit or jiva) which are all separately and independently real. And each atom and each soul possesses innumerable aspects of its own.
Every object possesses innumerable positive and negative characters. It is not possible for ordinary people, to know all the qualities of a thing. An ordinary person can know only some qualities of something. Human Knowledge is necessarily relative and limited and so are all our judgments. This epistemological and logical theory of the Jainas is called SYADVADA.
As a matter of fact, both Anekantvada and Syadvada are the two aspects of the same teaching – realistic and relativistic pluralism.
So, Metaphysics = Anekantavada
Epistemology = Syadvada
Arguments for ANEKANTAVADA :
a) There are innumerable material atoms and innumerable individual souls which are all separately and independently real, having innumerable aspects of its own.
b) Experience proves that there are actually innumerable objects in this universe.
c) We find different kinds of knowledge. It proves a thing has a number of aspects.
d) When we perform a research, new qualities is found in an object. Hence, objects have innumerable qualities.
e) Plurality of JIVAS also supports ANEKANTVADA.
f) Definition of SAT supports ANEKANTAVADA. Here SAT(real) is defined as that which possess the three characteristics of production, destruction and permanence.
g) SAPT-BHANGI-NYAYA also supports it : Same object can have seven types of judgments.
h) Relativity of Knowledge also supports Anekatvada.
i) Presence of different philosophical views regarding the number and nature of ultimate reality supports anekantavada.
