Management and organization studies (MOS) scholarship is at a crossroads. The grand challenges (such as the climate emergency) humankind must face today require an improved contribution from all knowledge fields. The number of academics who criticize the lack of influence and social impact of MOS has recently grown. The scientific field structure of MOS is based on its members’ accumulation of symbolic capital. This structure hinders speaking truth to the elite dominating neoliberal society. Our literature review suggested that a deeper (...) interaction between MOS and philosophy could aid in improving the social impact of MOS. Specifically, an attitude by MOS scholars based on parrhesia (παρρησíα, to speak truth to power) could revitalize the field through heterodox approaches and, consequently, allow them to utter sound criticisms of the capitalist system. Parrhesia would lead MOS scholars towards a convergence of ethics and politics. We investigate whether daring to speak inconvenient truths to the powerful (some peers in the field and some individuals and corporations in society) can be a straightforward tool for revitalizing MOS. Boosting a candid philosophy-MOS interaction requires the fulfilment of three objectives: practical dialogue between these fields, reconsideration of the fields’ structures based on symbolic capital, and a post-disciplinary approach to philosophy. That fulfilment implies the delimitation of the MOS-philosophy interaction, a respectful mutual framework, mutual curiosity, and moving from prescriptive theoretical reflection towards more socially useful MOS. Ethical betterment through parrhesia could be the key to surpassing MOS stagnation. (shrink)
