Dr. Nicolaisen (2016) has claimed a refutation of the definition of relevance as provided by the present author. This present paper examines Nicolaisen’s arguments and finds that Nicolaisen has failed to consider the differences between defining the concept of relevance and the measurement instances of it. His arguments are, therefore, misdirected and irrelevant. The epistemological problems as discussed by Nicolaisen are important, but not in relation to the task of defining the concept of relevance. Furthermore, his “refutation” resembles the well-known mythical “proof” that bumblebees cannot fly. As a result, it is concluded that the relevance definition under discussion is still valid and it is the most fruitful one that has been suggested so far.
