The Completeness of Scientific Theories

The Completeness of Scientific Theories deals with the role of theories in measurement. Theories are employed in measurements in order to account for the operation of the instruments and to correct the raw data obtained. These observation theories thus guarantee the reliability of measurement procedures. In special cases a theory can be used as its own observation theory. In such cases it is possible, relying on the theory itself, to analyze the measuring procedures associated with theoretical states specified within its framework. This feature is called completeness. The book addresses the assets and liabilities of theories exhibiting this feature.
Chief among the prima-facie liabilities is a testability problem. If a theory that is supposed to explain certain measurement results at the same time provides the theoretical means necessary for obtaining these results, the threat of circularity arises. Closer investigation reveals that various circularity problems do indeed emerge in complete theories, but that these problems can generally be solved. Some methods for testing and confirming theories are developed and discussed.
The particulars of complete theories are addressed using a variety of theories from the physical sciences and psychology as examples. The example developed in greatest detail is general relativity theory, which exhibits an outstanding degree of completeness. In this context a new approach to the issue of the conventionality of physical geometry is pursued.
The book contains the first systematic analysis of completeness; it thus opens up new paths of research.
For philosophers of science working on problems of confirmation, theory-ladenness of evidence, empirical testability, and space--time philosophy (or students in these areas).
