Humans are amphibians - half spirit and half animal. As spirits they belong to the eternal world, but as animals they inhabit time.
C. S. LewisThese, then, are the two points I wanted to make. First, that human beings, all over the earth, have this curious idea that they ought to behave in a certain way, and cannot really get rid of it. Secondly, that they do not in fact behave in that way. They know the Law of Nature; they break it. These two facts are the foundation of all clear thinking about ourselves and the universe we live in.
C. S. LewisMake your choice, adventurous Stranger, Strike the bell and bide the danger, Or wonder, till it drives you mad, What would have followed if you had.
