Abstract

The end of the nineteenth century is remembered as a time when psychology freed itself from philosophy and carved out an autonomous subject matter for itself. In fact, this time of emancipation was also a time of exile: while the psychologists were leaving, philosophers were slamming the door behind them. Frege is celebrated for having demonstrated the irrelevance of psychological considerations to philosophy. Some of Frege’s reasons for distinguishing psychological questions from philosophical ones were sound, but one of Frege’s most influential arguments, which was elaborated upon and advocated by the positivists, vastly overestimated the gap separating the two disciplines.
