This chapter discusses perceptual knowledge and uses the film Rain Man (1988) as an example. The film portrays a character who can visually ascertain the number of objects in large sets without counting. Here, the chapter demonstrates that a lack of awareness about how one acquires information or one's track record of reliability is sometimes the kind of gap that can preclude one from knowing even if one has relatively complete information, but the reverse is also true. A working familiarity with the source of one's belief P coupled with an awareness of the source's reliability can sometimes help make up for a relative lack of information about P itself.
