In the Christian religion, though perhaps not in any other, we frequently find a conception of god that is selfcontradictory and therefore corresponds to nothing. That is the conception formed by the following three propositions taken together:1. God is all-powerful.2. God is all-benevolent.3. There is much misery in the world. A god who was all-powerful but left much misery in the world would not be all-benevolent. An all-benevolent god in a world containing much misery would not be an all-powerful god. A world containing a god who was both all-powerful and all-benevolent would contain no misery. Here, then, we have a mathematical proof bearing on a common religious doctrine. Anyone who is confident that he frequently comes across misery in the world may conclude with equal confidence that there is no such thing as an all-powerful and all-benevolent god. And this mathematically disposes of official Christianity, as has long been known.Richard Robinson

For the first time (but how long will it take us to acknowledge this?) in the history of ideas, a philosopher had dedicated a whole book to the question of atheism. He professed it, demonstrated it, arguing and quoting, sharing his reading and his reflections, and seeking confirmation from his own observations of the everyday world. His title sets it out clearly: Memoir of the Thoughts and Feelings of Jean Meslier; and so does his subtitle: Clear and Evident Demonstrations of the Vanity and Falsity of All the Religions of the World. The book appeared in 1729, after his death. Meslier had spent the greater part of his life working on it. The history of true atheism had begun.Michel Onfray

The traditional arguments for the existence of God have been fairly thoroughly criticised by philosophers. But the theologian can, if he wishes, accept this criticism. He can admit that no rational proof of God's existence is possible. And he can still retain all that is essential to his position, by holding that God's existence is known in some other, non-rational way. I think, however, that a more telling criticism can be made by way of the traditional problem of evil. Here it can be shown, not that religious beliefs lack rational support, but that they are positively irrational, that the several parts of the essential theological doctrine are inconsistent with one another, so that the theologian can maintain his position as a whole only by a much more extreme rejection of reason than in the former case. He must now be prepared to believe, not merely what cannot be proved, but what can be disproved from other beliefs that he also holds. .John Leslie Mackie
