What do John Calvin, Sarah Palin, Jean-Jacques Rosseau, and Bon Iver have in common? A preoccupation with sincerity. With deep historical perspective and a brilliant contemporary spin, R. Jay Magill Jr. tells the beguiling tale of sincerity s theological past, its current emotional resonance, and the deep impact it has had on the Western soul. At a time when politicians are scrutinized less for the truth of what they say than for how much they really mean it, Sincerity provides a wide-ranging examination of a moral ideal that remains a strange magnetic north in our secular moral compass."
