In contrast to his views of some years ago Suppes in now convinced that modal concepts are essential to standard scientific talk. Yet he emphasizes two main points: (1) in a majority of cases the modal concepts remain implicit in that talk, and (2) this logic is scarcely used in either theoretical or experimental analysis of empirical phenomena. Furthermore, in dealing with probability and referring in particular to the sample space, he substantially says that modal concepts are left implicit to eliminate excess baggage.
In my opinion the situation emphasized by Suppes and described by him in detail, is quite natural and to be foreseen, up to details: Indeed, first, mathematization is the most important step in the qualitative development of science.
