'This book explains, defends, and promotes a traditional ('conjugal') idea of marriage with philosophical, non-faith-based arguments that also indicate why same-sex marriage is not marriage and why no-fault divorce law is incompatible with the institution of marriage. The authors give a clear and significant philosophical exposition of what's wrong with the ideas of marriage that have been developed in the literature (including court judgments) favoring same-sex marriage.' John Finnis, University of Oxford
