Models And Analogies In Science by Mary B. Hesse

A careful philosophical study arguing that models and analogies are central to scientific thought, functioning both as heuristic devices that suggest new hypotheses and as explanatory tools that give theoretical terms empirical content; it analyzes the logical structure of analogical reasoning—distinguishing positive, negative and neutral analogies—and shows how models mediate between abstract theory and observation, support theory construction and testing, and shape the semantics of scientific language, illustrated through historical examples from physics and biology.
