Third, in the re-investigation and refutation: according to that school, consciousness does not arise with a non-existent as its object; when cognising a rabbit's horn or the like, one previously saw the rabbit separately and previously saw the horn separately, combining them in one place, so it is not presently cognising a non-existent. If so, it would contradict the Buddha's teaching, because he spoke of knowing a non-existent as non-existent. Otherwise, there should only be cognition of what exists. The objection below regarding consciousness taking a non-existent as its object is a refutation of a hypothetical position.
