Abstract
This chapter is about a classical Indian debate about the Independent Check Thesis, the thesis that, if an agent is to rationally believe (or judge) that she knows that p, she must rely on some source of information that provides her independent evidence about the truth or reliability of her belief (or judgement) that p. While some Buddhists and Nyāya philosophers defended this thesis, the Bhāṭṭa Mīmāṃsakas rejected it. Here, I reconstruct the Bhāṭṭa Mīmāṃsakas’ arguments against the Independent Check Thesis. I show that these arguments reveal a tension between this thesis and a plausible principle that connects knowledge and action.
