Vincent Eltschinger has argued that Buddhist epistemology, especially Dharmakīrti's, was an apologetic response to attacks by hostile Hindu opponents and thus was seen by Buddhists as "that which, by defeating the outsiders, removes the obstacles to the path towards liberation." Coseru meanwhile simply notes the inseparability of epistemic concerns from spiritual praxis for Buddhist epistemologists such as Dharmakīrti:It is this praxis that leads a representative thinker such as Dharmakīrti to claim that the Buddha, whose view he and his successors claim to propound, is a true embodiment of the sources of knowledge. Thus, far from seeing a tension between empirical scrutiny and the exercise of reason, the Buddhist epistemological enterprise positions itself not merely as a dialogical disputational method for avoiding unwarranted beliefs, but as a practice aimed at achieving concrete, pragmatic ends. As Dharmakīrti reminds his fellow Buddhists, the successful accomplishment of any human goal is wholly dependent on having correct knowledge.
