God has had a substantial role in the history of philosophy. For example, Descartes attempts to escape solipsism by appeal to the clear and distinct idea of God; he also invokes the Almighty in his attempt to explain the problem of causal interaction. In addition, Berkeley required the intervention of God in order to account for the continued existence of the world not perceived. However, most (but certainly not all) modern philosophers are atheists; indeed many actually hold religion responsible for a great many of the world’s ails. Given the role that religion continues to play in our lives it is important for philosophy to consider the arguments for and against the existence of God.
