“If
I hadn’t spent so much time studying Earthlings,” said the Tralfamadorian,
“I wouldn’t have any idea what was meant by ‘free will.’ I’ve visited
thirty-one inhabited planets in the universe, and I have studied
reports on one hundred more. Only on Earth is there any talk of
free will.”
This quotation comes at the end of Chapter 4,
as Billy listens to his captors describe the true nature of time.
These words reveal that not only do Tralfamadorians have a completely
deterministic view of the universe in which every moment is structured
beyond the control of its participants, but that they also lack
an awareness of the possibility of free will. The alien who talks
to Billy is an exception, having encountered the peculiarly human
hang-up in his travels. But he maintains that humans, alone among
all beings in the universe, believe in the illusion of free will.
His emphasis on the idea of “studying” humans and inhabitants of
other planets makes humans (and their conception of free will) and
other non--Tralfamadorians seem like bizarre exceptions to the rule
of nature. He thus performs a reversal of the human tendency to
think of alien life as abnormal.
