We thought we knew the story of the twentieth century. For many in the West, after the two world conflicts and the long cold war, the verdict was clear: democratic values had prevailed over dictatorship. But if the twentieth century meant the triumph of liberalism, as many intellectuals proclaimed, why have the era's darker impulses—ethnic nationalism, racist violence, and populist authoritarianism—revived?

There was a time when liberalism was an ism like any other, but that time, writes Michael Walzer, is gone. “Liberal” now conveys not a specific ideology but a moral stance, so the word is best conceived not as a noun but as an adjective—one is a “liberal democrat” or a “liberal nationalist.” Walzer itemizes the characteristics described by “liberal” in an inventory of his own deepest political and moral commitments—among other things, to the principle of equality, to the rule of law, and to a pluralism that is both political and cultural.

In this classic work, Leo Strauss examines the problem of natural right and argues that there is a firm foundation in reality for the distinction between right and wrong in ethics and politics. On the centenary of Strauss's birth, and the fiftieth anniversary of the Walgreen Lectures which spawned the work, Natural Right and History remains as controversial and essential as ever.

Before the First World War, enthusiasm for a borderless world reached its height. International travel, migration, trade, and progressive projects on matters ranging from women's rights to world peace reached a crescendo. Yet in the same breath, an undercurrent of reaction was growing, one that would surge ahead with the outbreak of war and its aftermath. In this sweeping work of history, Tara Zahra examines how nationalism, rather than internationalism, came to ensnare world politics in the early twentieth century.

What exactly is capitalism? How has the meaning of capitalism changed over time? And what's at stake in our understanding or misunderstanding of it? In Capitalism, Michael Sonenscher examines the history behind the concept and pieces together the range of subjects bound up with the word. Sonenscher shows that many of our received ideas fail to pick up the work that the idea of capitalism is doing for us, without us even realizing it.
