Trained as a historian of medieval warfare, Yuval Noah Harari has become one of the most influential public intellectuals in the world, shaping global debates about artificial intelligence, human identity, and the future of society. Richard Utz traces how a medievalist moved from specialist scholarship to cultural prophecy-and why the habits of medieval history still matter for understanding his voice today.
A professional philosopher outside the academy walls can act as a popularizer (the goal here is to make philosophy more accessible to the general public), an applied ethicist (the major task is to offer an analysis of various specific moral issues that arise within a society), and a public intellectual (I limit this role to questions that have political connotation). Of course, there are overlaps between these roles and they certainly do not exhaust all possible forms of public engagement of a professional philosopher.
