ABSTRACT
Our discussion has concerned what will happen to a preference if we add beliefs to the body of beliefs founding a preference. In this chapter I shall ask instead whether qualitative changes in the body of beliefs might bring about preference changes. Suppose I found my preference on B1 and B2. What would happen if it turned out that the realization of B2 was not exactly what I imagined it would be like? This is another question than the one put in the previous chapter, and I will show why this is so.
