A stirring defense of liberalism against the dogmatisms of our time from an award-winning and New York Times bestselling author. Not since the early twentieth century has liberalism, and liberals, been under such relentless attack, from both right and left. The crisis of democracy in our era has produced a crisis of faith in liberal institutions and, even worse, in liberal thought. A Thousand Small Sanities is a manifesto rooted in the lives of people who invented and extended the liberal tradition. Taking us from Montaigne to Mill, and from Middlemarch to the civil rights movement, Adam Gopnik argues that liberalism is not a form of centrism, nor simply another word for free markets, nor merely a term denoting a set of rights. It is something far more ambitious: the search for radical change by humane measures. Gopnik shows us why liberalism is one of the great moral adventures in human history — and why, in an age of autocracy, our lives may depend on its continuation.
