Dr. Nicolaisen (2016) claimed the refutation of the definition of relevance provided by the present author. The present paper examines Nicolaisen’s arguments, finds that Nicolaisen fails to consider the difference between defining the concept of relevance and measuring instances of it, and that his arguments therefore are misdirected and irrelevant. The epistemological problems discussed by Nicolaisen may be 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. It is concluded that the relevance definition under discussion is still valid and the most fruitful one that has been suggested so far.
