One thing that you and I know is language. Another thing that you and I know is how objects behave in perceptual space. We have a whole mass of complex ways of understanding what is the nature of visual space. A proper part of psychology ought to be, and in recent years has been, an effort to try to discover the principles of how we organize visual space. I would say that the same is true of every domain of psychology, of human studies.
