As the Ricochet editors mentioned, tomorrow Encounter Books releases my new book, co-authored with Sherif Girgis and Robert P. George, What Is Marriage? Man and Woman: A Defense. So while blogging at Ricochet this week, I thought I’d explore some of the issues raised by the book—and recent events, thanks to the Supreme Court. Today I’d like to situate the debate over the definition of marriage within its proper context.
