Generally speaking, we typically regard objects of outer experience as other than our selves, thereby distinguishing them from objects of inner experience, which are within or part of our selves. The inner domain of experience includes our experience of objects inside ourselves, such as the inner world that we experience through our inner faculties of apprehension. These inner faculties include, among other possibilities, conceptual cognition, imagination, and intuition. Interpersonal Knowledge Knowledge that is public or interpersonal is knowledge that is shared, or agreed upon, by a community of individuals. For example, we all agree that there is a floor here beneath us.
Physicists agree with each other on the charge of the electron.
Mathematicians agree with each other that the Pythagorean theorem is true. Note that interpersonal knowledge is relative to a specific community of people and is associated with generally accepted methods and procedures for verifying the validity of their shared knowledge, thereby distinguishing it from private or personal knowledge. Personal Knowledge Private or personal knowledge is knowledge that is idiosyncratic and specific to individuals. For example, our dreams and fantasies are not usually accessible to each other. While I can know with certainty that I had a dream about an elephant stampede last night, there is no way you can verify or falsify this claim.
