Some people use “spirit” to mean that relatively supernatural element which is given to every man at his creation—the rational element. This is, I think, the most useful way of employing the word. Here again it is important to realise that what is “spiritual” is not necessarily good. A Spirit (in this sense) can be either the best or the worst of created things. It is because Man is (in this sense) a spiritual animal that he can become either a son of God or a devil.
