This brief and stimulating work is based on the prestigious Gifford Lectures, which Lenn Goodman was invited to deliver in 2005. Goodman was asked to speak about the commandment to 'love thy neighbour as thyself' from the standpoint of Judaism, a topic and perspective that have not often been joined before. Goodman's synthesis of Jewish values is formidable. His erudition, lucid prose, and courageous insistence on the ultimacy of human choice embarrass ignorance and undermine dogmatism of any stripe. And were not this sufficient, Love Thy Neighbor as Thyself also indicates that although the encounter of traditional religion with natural science generates more headlines and dazzling fireworks, that encounter pales in comparison to the urgent problem of reconciling confessional religious loyalty with the democratic principle of religious pluralism. In these desperate times of growing xenophobia and totalitarianism, both secular and religious, Goodman's humanistic plea for love and open-minded contemplation on the things of others is more necessary and welcome than ever.
