Along the way, Stark debunks many commonly accepted ideas. He interprets the sixteenth-century flowering of science not as a sudden revolution that burst religious barriers, but as the normal, gradual, and direct outgrowth of medieval theology. He also shows that the very ideas about God that sustained the rise of science led also to intense witch-hunting by otherwise clear-headed Europeans, including some celebrated scientists. This conception of God likewise yielded the Christian denunciation of slavery as an abomination--and some of the fiercest witch-hunters were devoted participants in successful abolitionist movements on both sides of the Atlantic. For the Glory of God is an engrossing narrative that accounts for the very different histories of the Christian and Muslim worlds. It fundamentally changes our understanding of religion's role in history and the forces behind much of what we point to as secular progress.
