Never cry wolf

"Somewhere to the eastward a wolf
howled; lightly, questioningly. I knew
the voice, for I had heard it many
times before. It was George, sounding
the wasteland for an echo from the
missing members of his family. But
for me it was a voice which spoke of
the lost world which once was ours
before we chose the alien role; a world
which I had glimpsed and almost
entered...only to be excluded, at
the end, by my own self."

Never cry wolf, by Farley Mowat

Scientific reasoning

...the statement that there exists a swan (∃(x)) which is not white (-Q(x)) is tantamount to saying that not all swans (-∀(x)) are white (Q(x)), i.e.,

∃(x) -Q(x). = -∀(x) Q(x).
