Generation of Questions

The aim of this Chapter is to introduce the concept of generation of a question by a set of declarative formulas. We shall also characterize the basic properties of generation. There are two possible ways of looking at generation. From the purely formal point of view it is a special case of evocation: it is the evocation of risky questions. But the proposed definition of generation can also be viewed as a new explication of the intuitive concept of the arising of a question from a set of declarative sentences. This explication is also an adequate one; yet, now adequacy is relativized to a new set of criteria. In the casese of evocation the conditions (Cd. 1), (Cd.2), (Cd.3) and (Cd.4) formulated in Chapter 1 played the role of requirements of adequacy; as far as generation is concerned, the relevant set of requirements of adequacy consists of the conditions (Cd. 1), (Cd.2), (Cd.4) and (Cd.5). Let us recall that the condition (Cd.5) is stronger than the condition (Cd.3). Consequently, the range of generation is narrower than the range of evocation. On the other hand, it seems that generation is more interesting from the point of view of possible applications; we shall discuss this in Chapter 8.
