Counting is a less precise tool for infinite sets than for finite ones. The shepherdess who can count her flock of a hundred sheep will know if the wolf has taken one; but, if she has an infinite flock, she won't notice until almost all of her sheep have been lost.
Peter J. Cameron
Up to now, I have not met him, but all I have done in this deep sea, more or less, are dedicated to him. However, he is not aware of it.
He is P. J. Cameron, an inspiration bold 1 for me.
