The field of modern logic is too extensive to be worked through by opencast mining. To open it up, we need to sink shafts and construct adits. This is the method of most text books: a systematic exposition of a number of main topics, supplemented by exercises to teach skill in the appurtenant techniques, lays a secure foundation for subsequent discussion of selected questions. Compared with this, the present treatment is more like a network of exploratory drillings to show that it would be worthwhile to start mining operations, or to work the existing shafts and adits, as the case may be. Within this metaphor we may also describe the inherent weakness of this conception: once a cavity is pierced, the duct's capacity will in general not be sufficient to carry away the discovered riches.... In keeping with the aim of this book - that of motivating concepts of modern logic and problems linked with them - I have chosen the following arrangement: the first half deals with so-called first-order predicate logic (as the kernel of modern logic), this being (I) analysed as a further development of traditional logic, (II) explained as theory of (really: as a surveyable discrete section from) the existent, whose language reflects so much of the latter's structure that it (III) can substitute for the existent as object of investigation (or has our 'discrete ontonlogy' suggested itself to us only because of the necessarily discrete structure of language?). Finally in (IV) we examine the correspondence between linguistic-deductive and ontic-relational structure. The second half presents (V) practical and fundamental extensions of the language of logic (and hence of the world picture afforded by it) and draws attention to the openness of all (VI) expressive and (VII) inferential means in this extended domain. This trivium of the non-trivial is supplemented by a look at (VIII) the logic of probability, which cannot be included under the extensions discussed earlier (V).' (-from the Preface).
