By Richard Dawkins

The God Delusion caused a sensation when it was published in 2006. Within weeks it became the most hotly debated topic, with Dawkins himself branded as either saint or sinner for presenting his hard-hitting, impassioned rebuttal of religion of all types. Dawkins attacks God in all his forms. He eviscerates the major arguments for religion and demonstrates the supreme improbability of a supreme being. He shows how religion fuels war, foments bigotry and abuses children.

By Karen Armstrong

Moving from the Paleolithic age to the present, Karen Armstrong details the great lengths to which humankind has gone in order to experience a sacred reality that it called by many names, such as God, Brahman, Nirvana, Allah, or Dao. Focusing especially on Christianity but including Judaism, Islam, Buddhism, Hinduism, and Chinese spiritualities, Armstrong examines the diminished impulse toward religion in our own time, when a significant number of people either want nothing to do with God or question the efficacy of faith. Why has God become unbelievable? Why is it that atheists and theists alike now think and speak about God in a way that veers so profoundly from the thinking of our ancestors?
