Recognizing that there are physical objects such as cats and triangular objects and red tomatoes, the medievels debated whether such "abstract objects" as cathood and triangularity and redness also exist by way of having a reality indepen­ dent of the concretely real things that exhibit them.

`...a wide-ranging, well-written, and highly readable study of scientific realism in relation to both scientific practice and such philosophical issues as metaphysical realism and epistemological fallibilism. The book is especially good in interpreting the significance of scientific progress; it also delineates important aspects of scientific method and clarifies the interaction between theory and experiment. Rescher lucidly explicates major positions, draws important distinctions, and develops instructive examples. His integration of methodological objectivity with ontological fallibilism is both distinctive and impressive.' Robert Audi, University of Nebraska-Lincoln, May 1987
