Critical ontology, ontic relationalism, and Being-principle are the three major concepts found in Kaipayil's thought.
Any ontological and metaphysical postulations we make can claim epistemic justification, only if they are grounded in our experience of the world.
[4][5] Coming to his relationalist thought, Kaipayil presents relationalism mainly as a theory of being, which addresses the metaphysical problem of the one and the many, i.e. the unity and the plurality of the world.
[6][7] Integral to Kaipayil's theory of being is his concept of Being-principle, conceived as the unity of the three primal principles - existence, intelligence, and force.
Mohanty[10] among others, Kaipayil argues that philosophy in India was equally rational and critical a pursuit as it was in the West.
