 Apperception makes certification possible because it sets up the item to be certified, showing the type of cognition the scoped is. Our apperceptive ability to determine whether the scoped cognition is putatively perceptual, inferential, analogical, testimonial, or of another character has epistemic relevance, since, as with all perception, there would be a presumption in favor of its correctness. Thus there would also be restoration of a presumption of the truth for a scoped cognition that had been brought into doubt were it judged to be perceptual, inferential, analogical, or testimonial in character, although further examination might prove the identification wong. Note that if further examination were called for, its direction would be determined by the apperception of cognitive type. For, the criteria of genuine perception, inference, and the rest vary according to origin. The characteristic epistemic merits and flaws (guṇa and doṣa) are very different for each knowledge source and there are also significant differences within species of perception in particular. Thus apperceptive judgment of putative type directs inquiry, telling us what to check.
