Drawing on Pepper's World Hypotheses we describe four different approa
ches to obtaining formal knowledge in management studies. These approa
ches are: formism, mechanism, contextualism, and organicism. All of th
em are valid ways of refining common sense that resist synthesis. Appl
ying Pepper's framework in as extremely diverse a field as management
studies (focusing on organizational behaviour (OB) and strategic manag
ement (SM) in particular) we show the different assumptions and knowle
dge claims made by different types of theorists in management and, mor
eover, we shed light on the sources of conceptual rivalry that often c
haracterize the field. By way of illustration, the Mintzberg-Ansoff de
bate on the nature of strategic management is focused upon for closer
examination. It is shown that analysing this debate in terms of Pepper
's framework one can understand and evaluate the epistemological diffe
rences between Mintzberg and Ansoff, which stem from their adherence t
o contextualist and mechanistic-cum-formistic types of knowledge respe
ctively.
