| Abstract: | Many “sociological”factors can account for the initial acceptance and continued persistence of W. M. Davis's Geographical Cycle. Such factors include Davis's attractive and forceful presentation of the cycle and the role of the cycle as a unifier of the discipline of physical geography, to name two. An analysis of the scientific character of the cycle, in the light of Karl Popper's criteria for demarcating between science and non-science, suggests that persistence of the cycle can also be attributed to a “logical”factor, the irrefutability of the central concept, stage. |
