How really real is real?

This paper takes issue with a number of family therapists who appear to hold that reality is entirely constructed out of our beliefs and that different views of reality can only be discriminated between on the basis of their usefulness for a particular purpose. Rather this paper argues for a co-constructivist position, that is, that the knower's beliefs and constructs are in an interpenetrating relationship with reality and that different views of reality can be discriminated between on the basis of their adequacy in describing that reality and that it is this adequacy that will determine their usefulness. These issues are not just of theoretical interest but have important implications for the practice of therapy.
