Thoughtful book on political tolerance in the US. Offers some compelling examples of our perennial problems: measurements can be very misleading, ideals should not be seen as universal but context dependent, and people have a remarkable way of believing things that make their side seem better.
This is a classic! It was published in 1982, but it has lingering value. It explores the basis of political tolerance in American democracy. Intolerance undermines democracy; thus, this volume addresses a critical issue. Still worth exploring. . . .
