All schools of Indian philosophy recognize various sets of valid justifications for knowledge, or "pramana" and many see the Vedas as providing access to truth. The Buddha denied the authority of the Vedas, though, like his contemporaries, he affirmed the soteriological importance of having a proper understanding of reality (right view). However, this understanding was not conceived primarily as metaphysical and cosmological knowledge, but as a knowledge into the arising and cessation of suffering in human experience. Therefore, the Buddha's epistemic project is different than that of modern philosophy; it is primarily a solution to the fundamental human spiritual/existential problem.
