How do you experience the world?

[stuiterbal]

Epistemology is the study of the nature of knowlegde. The DSM-IV Task Force was aware of the long-standing debate-beginning with Aristotle and Plate and renewed in the Middle Ages- over how the human mind percieves and constructs our world. We pondered the views of the following three umpires, each of whom has a very different understanding of the way in which their baseball world is experienced and organized: 
Epistemology I   : There are balls and there are strikes and I call them as they are.
Epistemology II  : There are balls and there are strikes and I call them as I see them.
Epistemology III : There are no balls and no strikes until I call them.
