Managers face increasingly volatile, uncertain, complex and ambiguous situations that are more and more challenging to navigate. Ethical decision-making has become particularly complicated considering that codes, frameworks and protocols have proven deficient in resolving moral dilemmas. Managers’ unpreparedness to handle such challenges reflects the ineffectiveness of business ethics education, calling for new approaches towards training managers. This article makes a case for transforming business ethics education by taking it back to its roots. This implies the re-incorporation of its foundational discipline: (...) philosophy. Philosophy offers a rigorous approach for decision-making, which helps managers face the unknown. It helps them analyse situations from different perspectives, reconsider how things are done and examine the underlying premises of their thinking. It can strengthen one of the most central managerial competencies: the ability to reason, especially ethically. As the foundational discipline of business, ethics and their intersect, philosophy is uniquely positioned to elevate business ethics education for managers at all levels. It can help current and future managers to reflect more deeply and critically on the ethical issues they face. (shrink)
