  There is some dispute as to whether or not Dharmakīrti retains  the causal model of perception in the case of internal objects. Thus, Dreyfus (1997, 336f) takes the view that Dharmakīrti is  effectively compelled to admit that for a perceptual aspect to  acquire cognitive status it must be interpreted. As such, it acquires the status of an internal mental representation, which Dreyfus claims to be “a highly uncomfortable position” for  Dharmakīrti given his commitment to the view that perception  must be foundational for knowledge.
