Summary
INTRODUCTION
This chapter discusses representation of scientific theories and reasoning in theory change. A scientific theory may be represented by a set of concrete exemplary problem solutions. Or, alternatively, a theory may be depicted in an abstract pattern, which when its variables are filled with constants becomes a particular explanation. The exemplars and abstractions may be depicted diagrammatically, as they are in the cases from Mendelian and molecular genetics to be discussed. One way that a theory grows is by adding new types of exemplars to its explanatory repertoire. Model anomalies show the need for a new exemplar; they turn out to be examples of a typical, normal pattern that had not been included in the previous stage of theory development. A special-case anomaly indicates the need for a new exemplar or abstraction, but it has a small scope of applicability. Thus, our subjects here are exemplars, abstractions, diagrammatic representations, and anomalies and the roles they play in the representation of explanatory theories and in the change of such theories. Examples will be taken from Mendelian and molecular genetics.
EXEMPLARS, ABSTRACTIONS, AND DIAGRAMS
Thomas Kuhn (1970, 1974) discussed the importance of “exemplars,” which he characterized as concrete problem solutions in which a formalism is applied and given empirical grounding. Kuhn said that exemplars are taught by the use of problems in textbooks.
