 But does this talk of ascertainment then mean that the Buddhist Epistemologist adopts an internalist account of epistemic justification? Is the Buddhist saying that when you genuinely know something, you need to know that you know it, i.e., be able to establish to yourself and others that you have the requisite justification?  [32]  It is not at all clear that Dharmakīrti or his Tibetan interpreters were internalists about epistemic justification. Nothing in his own talk of “ascertainment” clinches an internalist interpretation that the person who infers must also himself access the reason and ascertain with a pramāṇa that it does justify the inference. When the debater ascertains the characteristics of the reason, all this may mean is that a person making an inference must only in fact have followed a number of reliable procedures to initially determine the characteristics of the reason. It need not mean that when one knows something inferentially one must also be aware of the justification basis, i.e., the reason, and know that it does indeed justify the inference.
