Fantasy
“Immortality” in science fiction (sf)
can mean just that someone is immune to disease and old age but not also to
accident or violence. He is not indestructible. By contrast, in Neil Gaiman’s
fantasy series, The Sandman, the source of Hob Gadling’s immortality is
supernatural, not chemical or genetic. The anthropomorphic personification of
Death has agreed not to come for Hob. Consequently, he enjoys, or endures, more
than just perpetual good health and middle age: he can be immersed, burnt and
deprived of food but cannot be drowned, burnt or starved to death.
Hob’s immortality differs from that of
Bernie Capax who is older – he remembers the smell of mammoths – but who meets
Death when a wall collapses. Bernie then learns that his soul has a different
kind of immortality. The fantasy Sandman presents the full panorama of
Heaven, Hell and states between. Although Hob, like a few other deathless men,
welcomes his physical immortality, The Sandman presents two other
characters who, having become physically indestructible, long for extinction,
the mythical Orpheus and the super-heroine Element Girl. (All mythologies and
many comic book characters co-exist in this series of “graphic novels.”)
Fictional vampires have the same problem
of living indefinitely and needing to conceal their longevity but we know how
they can be killed.
SF
Although there are many other examples,
I will mention briefly just twelve instances of sf immortality. Of the three
Campbell future historians, Robert Heinlein, Isaac Asimov and James Blish, two
addressed the idea. In Heinlein’s Future History, the Howard Families breed for
longevity. After a few generations, they live well into their second century.
The oldest member present chairs meetings. Like Hob and similar characters, they
practice what they call the Masquerade: to conceal the fact of longevity, they
periodically move elsewhere and change their identities. Later, public
disclosure of the Howards’ longevity inspires a research project that finds a
means of indefinitely extending anyone’s life span. Such artificial means of
longevity exist in other works to be mentioned below but, first, there is
another idea in the Future History.
An early Howard, Lazarus Long, lives
indefinitely, for millennia, and becomes “the Senior”, the oldest member of the
human race. Thus, he is a mutation who need not have been born to Howard Family
parents. “Lazarus Long” is a Masquerade name. His birth name, Woodrow Wilson
Smith, is a clue to his real age. In The Boat Of A Million Years by Poul
Anderson, a small group of such mutations survives through recorded history and
into an indefinite future. Crossing interstellar space, they split up but plan
to meet again in another million years.
Of course, Anderson could not possibly
have written what these characters would be like after a million years. By that
time, either they would all have died in accidents or those who yet survived
would have become different characters. How much would they even remember? Each
of them had already preserved his or her sanity by somehow marshaling inner
resources in order to resist being overwhelmed by accumulating memories. By
living that long, they perform functions that are usually performed by
successive organisms without a memory accumulation problem. Death is the natural
mechanism for memory deletion.
In Asimov’s future history, extra-solar
colonists, inhabiting a germ-free environment, extend their life spans well into
a second century and usually record their age in decades, not in years. A year
becomes more like a month on that time scale. The only immortal being in this
future history is a humaniform robot, not a human being. Thus, Robot Daneel
Olivaw, having been introduced in the Robot novels, appears again millennia
later in the Foundation novels which had originally been an unrelated series.
In James Blish’s Cities In Flight
future history, antigravity and antiagathics make interstellar travel possible.
Star-traveling characters live for centuries although we only realize later in
the main volume that so much time has elapsed since the beginning of the book.
Logically, some of the characters happen to live until the end of the universe
although, for story purposes, that ending is brought much closer to the present
than we would have expected. In fact, the date given, 4004 AD, contradicts
suggestions in the previous volume that several millennia have elapsed during
the interstellar period. Despite antiagathics, everyone dies but new universes
begin.
In Larry Niven’s Known Space
future history, “boosterspice” performs the same function as antiagathics. Further, protector-stage humanoids are immortal, although at the expense of no longer
being “breeders”. However, in his alternative future history, A World Out Of
Time, Niven imagines an elegant alternative source of immortality. If
teleportation is possible, then the chemicals associated with aging can be
teleported out of the body. Thus, the instant elsewhere is a young forever. It
is perhaps a more acceptable form of immortality than another in the same book
which arrests physical development before puberty, producing immortal children
who must preserve mortal adults for breeding.
In Anderson’s Psychotechnic History,
modeled directly on Heinlein’s Future History, it is suggested that an organism
can be made immortal only by shielding it from all radiation, thus by
incarcerating it underground, consequently producing a human being with an
extremely limited experience and mental range. Scientists care for an immortal
hospital patient: a dead end. Appropriately, this story is called “What Shall It
Profit?” In Anderson's Technic History, “antisenescence” explains why Dominic
Flandry remains active and might yet have more children although he is nearly
seventy. However, antisenescence delays aging but does not prevent death.
By contrast, in Anderson’s World
Without Stars, every human being uses “the antithanatic.” A few immortals
lead changeless lives on planetary surfaces or in orbiting space stations but
many trade and explore endlessly between galaxies which are made accessible by a
series of instantaneous jumps in a spaceship. Many memories are artificially
deleted to prevent cerebral overloading but it is necessary to preserve the
overall pattern of the past and the important details. Hugh Valland, three
thousand years old, remembers Mary O’Meara who died young in 2037 just before
she would have had access to antithanatic. He revisits her grave on Earth as if
revisiting a living woman and recounts experiences on many planets but must also
have deleted many intermediate memories. He has somehow made sense of his
indefinite longevity by focusing on one set of memories.
At any given time, what exactly does
Hugh Valland remember? First, he has normal memories of whatever he has
experienced since his most recent memory deletion. Secondly, he preserves vivid
memories of Mary O’Meara. Thirdly, he remembers the pattern of his life since
leaving Mary. Fourthly, within this pattern, he has perhaps a natural life
span’s worth of memories of experiences in space, on other planets and back on
Earth. However, he must have had to delete far more details than he has been
able to retain. He maintains his purpose and remains celibate by focusing on
ever fresh memories of one person. Only at the end when we realize that that one
person is long dead do we doubt Valland’s sanity.
It seems appropriate to begin a brief
consideration of fictitious immortality with the fantasy character Hob Gadling
and to end with the sf character Hugh Valland.
