The field of management research is commonly regarded as or aspires to be a science discipline. As such, management researchers face similar methodological problems as their counterparts in other science disciplines. There are at least two ways that philosophy is connected with management research: ontological and epistemological. Despite an increasing number of scattered philosophy-based discussions of research methodology, there has not been a book that provides a systematic and more comprehensive treatment of the subject. This book addresses this gap in the market and provides new ideas and arguments for guiding management researchers.
