Aristotle's Rhetoric presents a number of problems for interpreters. It contains criticisms of sophists, yet seems to teach sophistical techniques of persuasion. It is unclear to some readers whether the book is an elaboration of a rational discourse or not. And its diversity of material has led some to view it as a collection of texts rather than as a unified book. In his commentary Arnhart argues that Aristotle's Rhetoric is a coherent account of public speech as a kind of (...) rational discourse less rigorous than scientific demonstration but more rational than sophistry.

If one wishes to understand medieval philosophical descriptions of the nature of the various sciences, a familiarity with the scientific knowledge possessed at that time is necessary. An excellent example of the basic characteristics of medieval mathematics can be found in this critical edition of De numeris datis. The work itself is the first advanced algebra text produced in Western Europe. It is a study of the general methods of solving problems for unknown numbers if one knows, is given, other (...) numbers and the relationships between them. Although the mathematical ideas Jordanus presents will be familiar to readers of this book, their development differs from that of contemporary algebra. The differences illuminate the medieval approach to mathematics. Medieval mathematicians approached this sort of problem by starting with the known numbers and working through to the unknown rather than concentrating on manipulation of the unknown variables as is done in modern approaches to mathematics. Medieval mathematics also viewed numbers as semi-geometric things. Solutions to algebraic problems were often seen in terms of geometric approaches to the areas and sides of rectangles. In this work Jordanus follows a more "algebraic" approach, but this approach did not replace the dominant medieval geometric approach to mathematics. In fact, as Hughes notes, the marginal notations in later copies of the work are usually geometric diagrams of the concepts. One can read such statements about medieval mathematics easily enough, but if one reads medieval mathematical thought in its original form the sort of thinking involved in medieval mathematics is much clearer. Such a background is useful in interpreting the descriptions writers like Aquinas offer of the nature of mathematics. (shrink)

Debates over affirmative action are often frustratingly uninformative and inconclusive. In this work Capaldi goes beyond criticizing that policy to clarify why the debaters miss each other's points. He begins by attacking affirmative action and establishes the need to explore the theory supporting it. Following this exploration he concludes that this policy involves dangerous fundamental changes in the structure of society and outlines a response. The timing of the publication of the book was such that it was unable to take (...) into account the Grove City decision. Its analysis of the kinds of thought characteristic of both sides of the debate, however, is very useful when examining the current debate over the appropriate response to that decision. (shrink)
