Conceptual Integrity without Concepts

It is commonly asserted that one of the most crucial factors in software design is the adoption of consistent and appropriate concepts. This widespread assumption, underlying several researches in software engineering, tacitly postulates the very existence of concepts. What, then, if concepts do not exist? This is the question asked in this paper, where the articulation of possible answers is attempted. As weird as it might sound, doubts on the existence of concepts have been recently cast by few distinguished philosophers of mind, with compelling arguments. One such argument is the heterogeneity of cognitive assets that can be referred to a single concept, and we show that it might be the case for design concepts in the example of Blender, a 3D computer graphics software
