Nicolaus Copernicus

Of all things visible, the highest is the heaven of the fixed stars.

To know that we know what we know, and to know that we do not know what we do not know, that is true knowledge.

At rest, however, in the middle of everything is the sun.

Deep down, there is in the substance of the cosmos a primordial disposition, sui generis, for self-arrangement and self-involution.

I feel sorry for generations of Labour voters and supporters who must look and wonder what on earth has gone wrong and what Labour is for.

How well I have learned that there is no fence to sit on between heaven and hell. There is a deep, wide gulf, a chasm, and in that chasm is no place for any man.
