C. S. Lewis Quote

The naturalists have been engaged in thinking about Nature. They have not attended to the fact that they were thinking. The moment one attends to this it is obvious that one's own thinking cannot be merely a natural event, and that therefore something other than nature exists. The Supernatural is not remote or abstruse; it is a matter of daily and hourly experience, as intimate as breathing.
