Every generation puts its own spin on love and romance. Just ask millenials, whose highly fluid, label-averse approach to dating has become the stuff of hit TV shows such as "Girls," as well as hand-wringing over the possible decline of courtship.
But even as rules and expectations evolve, the mechanics of attraction remain the same, and the principles of romance—respect, restraint, honesty, etc.—are as important (and as difficult to master) as ever. Long before one could learn from Hannah Horvath’s mistakes, live vicariously through Anastasia Steele, or take down notes from "The Art of Seduction" love-seekers were beset by the same questions, frustrations and desires. For much of history, the most reliable resources to turn to were the annals of religion—one could even call them the world’s first advice books. Religion is still an unparalleled source of romance advice, and these books distill wisdom from major world faiths that’ll steer you in the right direction.
