God, Suffering and Solipsism

'Solipsism' refers to the radically skeptical thesis that no one is justified in believing that there is a world beyond present, subjective states of consciousness. The French philosopher, Rene Descartes, undertook to overcome solipsism by setting out some proofs of God's existence and then arguing that, since God is perfectly good, he would not permit enlightened common sense to be deceived about the existence of an enduring external world.
