In 1943, the final year of her life, unable to join the resistance movement in France, she worked in London for the Free French government in exile. Here she was commissioned to outline a plan for the renewal of Europe after the scourge of Nazism. The Need for Roots was the direct result. In it she seized the opportunity to denounce the false values of contemporary civilisation. In the cult of materials she witnessed a devastating loss of spirit and consequently of human values. To counteract this she sets out a radical vision for spiritual and political renewal with a passion for truth which sweeps through these pages. The book has become a lasting spiritual testament for our age, where we are confronted, as T.S. Eliot comments, by a 'genius akin to that of the saints'.

     His starting point is moral intuition—the nearly instantaneous perceptions we all have about other people and the things they do. These intuitions feel like self-evident truths, making us righteously certain that those who see things differently are wrong. Haidt shows us how these intuitions differ across cultures, including the cultures of the political left and right. He blends his own research findings with those of anthropologists, historians, and other psychologists to draw a map of the moral domain. He then examines the origins of morality, overturning the view that evolution made us fundamentally selfish creatures. But rather than arguing that we are innately altruistic, he makes a more subtle claim—that we are fundamentally groupish. It is our groupishness, he explains, that leads to our greatest joys, our religious divisions, and our political affiliations. In a stunning final chapter on ideology and civility, Haidt shows what each side is right about, and why we need the insights of liberals, conservatives, and libertarians to flourish as a nation.
