Excerpt from Inferring Ignorance From the Locality of Visual Perception One particular type of reasoning that mav be supported by a theory of perception is the inference that an agent must be ignorant of a particular fact because he has had no way to find out whether it is true. Such means of inferring ignorance may be important, either to infer that a secret may be safely kept from another party. Or to guide an agent in planning a method to find out a given fact. Previous theories of knowledge have not supported any strong methods of inferring ignorance. Other than a backward use of consequential closure: If A does not know Q but A does know that P implies Q, then A must not know P. A theory of knowledge can thus be made a much more powerful tool when it is associated with a theory of perception.
