History is not the arena in which natural scientists look for the truth; quite the contrary, they believe it cannot be found there but rather in the laboratory. From their point of view history will at best yield up stale truths that have been superseded.

For such fields deep historical studies can have considerable contemporary relevance and hence fall within the boundaries of the field itself. Weber and Durkheim are still studied by sociologists, just as Adam Smith and Ricardo are still studied by economists, whereas Galilean and Newtonian studies are not part of physics but of an altogether different discipline, the history of science.

The term “introspective psychology” is misleading in that it covers a variety of diverging positions on the theory and practice of introspection. From the beginning there was a basic discrepancy between the British and the German philosophic tradition, the former relying more exclusively on introspection than the latter. Wilhelm Wundt’s advocacy and use of introspection was extremely circumscribed and essentially limited to simple judgments tied to external stimulation. During the first decade of the twentieth century some experimental psychologists, notably E. B. Titchener and the , greatly enlarged the scope of introspection, ushering in the brief vogue of “systematic introspection.” The latter never gained wide support in North America and was supplanted in Germany by developments that do not constitute “introspective psychology” in any precise sense.
