The Novel and the Film
screenplay for the film and the complexities
within the original novel inevitably created a
different story-line for the film. One of the
major deletions taking place during the
adaptation of the novel was the mystical,
enigmatic-messiah-character called Wilbur
Mercer, and his ideals called "Mercerism".

By grasping the handles of what is
described as a "black empathy box" the
characters are able to begin "fusion" with
Wilbur Mercer and simultaneously with anyone
else who, at that moment in time, are using an
empathy box. This "fusion" consists of sharing
one's own thoughts and feelings with other
people and understanding and experiencing their
thoughts. Mercer is portrayed as an elderly man
dressed in a "dull featureless robe",
perpetually ascending a relentless hill within a
barren hostile environment. Rocks are thrown by
unseen tormentors whilst one ascends, and
physical harm can result if contact is made by
these missiles.

This "physical merging accompanied by

mental and spiritual identification" has the
ability to take away mental loneliness, which is
very important within a world where most of the
animal population is extinct. It is this human
desire to own a real pet or animal that
dominates the novel's story-line compared to the
film.

Rick Deckard is prepared to risk his own
life by trying to earn enough bounty money to
purchase a real live sheep or any natural
animal, so that he can care for it as a family
pet. It represents a kind of social status to
own an authentic animal, rather than an electric
replicant or android. It seems to demoralise a
person or family and reflects negatively with
other people or neighbours. This can supposedly
deprive them of true "fusion" with Mercer. The
ascent of the hill in "fusion" represents their
individual life: ascending for approaching
honourability. It is also considered bad
etiquette to enquire if someone's animal is
genuine or not.
