..and a quote from Celia Green's The Human Evasion:
"On the face of it, there is something rather strange about human psychology.
Human beings live in a state of mind called 'sanity' on a small planet in space. They are not quite sure whether the space around them is infinite or not (either way it is unthinkable). If they think about time, they find it inconceivable that it had a beginning. It is also inconceivable that it did not have a beginning. Thoughts of this kind are not disturbing to 'sanity', which is obviously a remarkable phenomenon and deserving more recognition."
