A growing number of powerful arguments have been formulated by philosophers and logicians in recent years, demonstrating that the existence of God is improbable. These arguments assume that God's existence is possible, but argue that the weight of the empirical evidence is against God's actual existence. This unique anthology collects most of the important arguments that have been published since the mid 1900s. The editors make each argument clear and accessible by providing a helpful summary arranging the diverse collection into four thematic groups - the cosmological, teleological, inductive evil, and non-belief. The list of distinguished authors offer an indispensable resource in the philosophy of religion.
