CS Lewis in Mere Christianity:
Everyone had 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. You are not children; why should you be treated like children?
