Abstract

There have been many fine studies of Galileo in recent past, but practically all of these have been the work of historians of science who are not professionally trained as philosophers and yet who, by the very nature of the subject they are treating, get themselves involved in philosophical tangles. Shapere takes off from a number of these works and subjects them to close philosophical scrutiny; his resulting analyses are clever and incisive, and offer a prime example of how the philosopher can come to the assistance of the historian, even though the latter may be unaware of his need for help. The burden of Shapere’s work consists in a critical examination of the preconceptions and presuppositions that underlie three common interpretations of Galileo’s contribution.
