Sir Robert Rede's Lecture 2026: Reason versus Rationality: A History

Reason versus Rationality: A History

In English, "reason" and "rationality" are often used interchangeably. Yet from Enlightenment probability theory to Cold War game theory to contemporary economics, the precepts - and, more alarmingly, the practices - of reason and rationality have repeatedly diverged. A long history reveals how these two ideals, although twinned at birth, drew apart from each other. Rationality came to refer to formalized procedures and reason to the delicate assays of deliberation and judgment. These rival ideals now compete in consequential decisions about everything from nuclear strategy to the viability of democracy.
