Abstract: If we ignore religious experience, there is enough evidence considered in this book, to make the existence of God as probable as not. Theism is a simple hypothesis which leads us to expect many phenomena which are not otherwise to be expected. The principle of credulity considered in Chapter 13 has the consequence that we ought to believe that what we appear to experience is really there unless there is considerable counter-evidence. Hence, the religious experience (of ourselves or others) when added to the other evidence makes it probable on balance that there is a God.
