"The point of a well-defined concept is that it provides not, normally, a ‘description’ of parts of the real world but rather an epistemology in terms of which the buzzing, blooming, changing complexity of the world can be researched, explored, investigated, made sense of and perhaps changed. Armed with the sharply defined concept, you are asking: is there a correlation, a mapping, between the concept and parts of the perceived world? That question is the source of the learning about the world."
