A note on the aphorism “there is nothing as practical as a good theory”

Purpose The purpose of this paper is to consider one inaccuracy in the written record of our discipline. That is, how the aphorism “There is nothing as practical as a good theory” came to be regarded as Kurt Lewin’s signature saying. Design/methodology/approach Primary and secondary sources were used in the research. Findings By tracing the history of the above-captioned aphorism back through its use by the General Electric Company in the 1920s to Friedrich W. Dörpfeld’s 1873 book Grundlinien einer Theorie des Lehrplans, zunächst der Volks- und Mittelschule , it can confidently be concluded that it did not originate with Lewin. Practical Implications Those who study history soon become aware that inaccuracies in the written record are commonplace. Indeed, assuring historical accuracy has been a challenge confronted by historians for centuries. Originality/value The widespread acceptance of Lewin as the originator of the referenced aphorism underscores the observation that received knowledge is often wrong. It also provides one more illustration that, whatever their origin, once errors of attribution appear in print, they become diffused and amplified, taking on a life of their own as they are transmitted from generation to generation.
