[This book] is essential reading for anyone who has an interest in the complicated legal, philosophical, and historical issues that are behind our contemporary debates about marriage and the family. Unfortunately, the way these debates are often conducted online, in public, and at universities and colleges—usually accompanied by rhetorical excesses and personal recriminations—they rarely reveal that the plausibility of each side’s case depends on deeper principles that are far from uncontroversial. In this regard, American Constitutionalism, Marriage, and the Family is a breath of fresh air.
