Whistleblowing” has entered the scholarly and the public debate as a way of describing the exposure by the member of an organization of episodes of corruption, fraud, or general abuses of power within the organization. We offer a critical survey of the main normative theories of whistleblowing in the current debate in political philosophy, with the illustrative aid of one of the epitomic figures of a whistleblower of our time: Edward Snowden. After conceptually separating whistleblowing from other forms of wrongdoing (...) disclosures, we introduce and discuss two families of normative views of this practice: the “Extrema Ratio” and the “Deontic” views. We show how the two views can be usefully considered in tandem to offer an all-round assessment of the moral justification of whistleblowing either as an extraordinary individual conscientious act of indictment or as an ordinary dutiful organizational practice of answerability that enables the capacity of self-correction of an organization.
