The ethical problem of privacy lies at the core of computer ethics and cyber ethics discussions. The extensive use of personal data in digital networks poses a serious threat to the user’s right of privacy not only at the level of a user’s data integrity and security but also at the level of a user’s identity and freedom. In normative ethical theory the need for an informational self-deterministic approach of privacy is stressed with greater emphasis on the control over personal (...) data. However, scant attention has been paid on a virtue ethics approach of information privacy. Plotinus’ discussion of self-determination is related to ethical virtue, human freedom and intellectual autonomy. The Plotinian virtue ethics approach of self-determination is not primarily related to the sphere of moral action, but to the quality of the self prior to moral practice. In this paper, it is argued that the problem of information privacy should be reconsidered in the light of Plotinus’ virtue ethics and his notion of self-determination. (shrink)
