"Everyone has warned me not to tell you what I am going to tell you in this last book. They all say ‘the ordinary reader does not want Theology; give him plain practical religion’. I have rejected their advice. I do not think the ordinary reader is such a fool. Theology means ‘the science of God,’ and I think any man who wants to think about God at all would like to have the clearest and most accurate ideas about Him which are available."
