What Kind of Approach This Study Takes and What It Does Not

We may believe we have a good intuition about what “rationality” is. It has something to do with reasoning. Employing it in daily use is reputed to help improve our lives. It is not tied to a religion, although the religious may use it as effectively as anyone. Perhaps some agents may use it better than others. It may involve a capacity. But, while all these cases apply to some degree to rationality, as a whole they do not even seem to capture rationality in one swoop. For that reason, this book aims to set forth a theory, explanation, and unification of the kindred and disparate understandings of this elusive concept, rationality.
