Abstract
The necessity of epistemological theorisation for management science is questionable. However, epistemology can be useful if the following distinction between three kinds of epistemology, usually overlooked, is taken into account: epistemology as a structured academic discipline, epistemology as an intellectual exercise produced outside academic epistemology, and finally the epistemology specific to each researcher. When this distinction is not made, epistemology can become counterproductive and impede scientific work.
