In his presentation at the 1993 Society of Business Ethics conference, Ed Freeman offered a provocative explanation for why the normative core of business and society (B&S) research is perceived as fundamentally at odds with the pervasive wisdom on business and the academic literature on management (e.g., "business ethics is an oxymoron"). He termed this explanation the separation thesis. This article explores the possibility that the separation thesis captures a pervasively held view about corporations, even among B &S researchers. To (...) support this claim, the author looks at whether three value dichotomies, which provide the conceptual underpinnings of the separation thesis, are prevalent in the literature. The article provides evidence from the literatures in ethics, corporate social responsibility/ performance, and wider management issues to support its claims, and then looks at alternative possibilities for developing inquiry to avoid the pitfalls of these value dichotomies and, therefore, the separation thesis.
