Anekantavada is a core theory and philosophy of which one of the following ?

Anekāntavāda is the central philosophical doctrine of Jainism, often translated as “non-one-sidedness,” “many-sidedness,” or “non‑absolutism.” It teaches that reality is complex and can be apprehended only from multiple perspectives, so no single categorical statement captures the whole truth; all assertions must be qualified by context and standpoint. Scholarly summaries and encyclopedic entries identify Anekāntavāda as a fundamental Jain doctrine linked with related logical doctrines like syādvāda and nāyavāda, and trace its articulation to the Jain tradition and the teachings of Mahāvīra [1]. Jain expositions likewise present Anekāntavāda as the central, distinctive Jain approach to truth and tolerance.
