When we talk of inquisition it is usually prefaced with a definite article — as in, The Inquisition. But, as Vanity Fair editor Cullen Murphy points out in his new book, God's Jury, the Inquisition wasn't a single event but rather a decentralized, centuries-long process.
Murphy says the "inquisitorial impulse" is alive and well today — despite its humble origins with the Cathars in France, where it was initially designed to deal with Christian heretics.
