John Stuart Mill's On Liberty--just the 2nd chapter--made accessible for the 21st century, with gorgeous illustrations. Reeves (a biographer of Mill) and Haidt (a social psychologist) summarize Mill's three timeless arguments for free speech and the value of viewpoint diversity. They then reduce the text to half its original length, allowing Mill's best arguments and metaphors to shine. Artist Dave Cicirelli illustrates those metaphors to amplify their intuitive power. Ideal for use in college courses, or in any organization in which people would benefit from productive disagreement.
