Three conclusions emerge from the accounts of the external senses. First, each has a characteristic field of perception. Second, further claims about sensed objects may require interpretation, evidence and reason. Third, in this theological framework the senses do not independently create knowledge without divine agency.
Hearing someone's voice is a sensory occurrence; understanding the speech involves comprehension; establishing the claim's truth requires warrants concerning testimony and evidence.
The ordinary value of sensation is therefore not denied, but neither should every impression be treated as an infallible judgment.
The truth of testimony is not settled merely by the audibility of words. The reliability and content of a report require appropriate grounds for belief.
