In my essay AND THE HALF-TRUTH SHALLSET YOU FREE, I noted one of the vital distinctions between
philosophy and literature: that philosophy attempts to suss out truth
from falsehood, while literature’s primary function is to promote
fictions that have an ambiguous relationship to “truth,” whatever
a given artist’s personal convictions may be. For instance, Dave
Sim may believe explicitly in the revelations of the “Peoples of
the Book,” but he’s still encoding those beliefs within the
context of the fiction called CEREBUS.
Numerous philosophers have come up with
metaphors for the search for truth, but in my personal opinion no one
has ever topped Plato’s “Allegory of the Cave," summarized thusly:
Plato tells of men who have remained closed since they were children in a subterranean cave, chained so that they can only see the bottom of the cave.
Behind them stands a high and remote light, and between the light and the prisoners there is a wall that runs alongside a path. On the path walk some people carrying different objects, some argue, others do not.
Whoever is in the caves, having never observed the true object, thinks that the shadow cast at the bottom of the cave must be the real object, and that the echoes are the true voices of those people.
A prisoner frees himself and goes up the cave.
For him it is long and painful, because his eyes, which are not accustomed to light, hurt so much more that he approaches the opening of the cave.
Once accustomed, however, the prisoner can see that the shadows were only the projection of the objects brought by the servants behind the wall and now he thinks these are the real objects.

The dominant interpretation of the
allegory is that the chained people in the cave, able to perceive
only shadows of the reality beyond the cave, symbolize human
confinement to the input of their physical senses. According to the
idealism of Plato (sometimes given the chimerical name of “Realism”),
the World of Forms is the actual Truth Beyond the Cave, and
presumably the individual who escapes the cave, and tries to convey
that insight to his chained fellows, symbolizes the dilemma of the
Platonic philosopher.
In addition of my deeming this the best
of the “truth-seeking” metaphors, I would hazard that this may be
the best known metaphor in philosophy as a whole, given that it
furnishes the reader with all the basic challenges of epistemology.
Further, the Cave-Allegory may be seen as consequential for the two
major branches of metaphenomenal fiction: what we call “fantasy”
and “science fiction.”
There have been dozens of involved
histories of both “super-genres,” but I’m most concerned with
the ways in which both categories developed in the late 1800s.
Despite many significant precursors, the two super-genres receive
their greatest codification in this period, when Jules Verne and H.G.
Wells defined science fiction and William Morris defined the
alternate-world fantasy. (To be sure, horror fiction undergoes a
similar codification in this period, but many works in this genre
make so much use of either “fantasy motifs” or “science fiction
motifs” that I can’t think of horror as being entirely separable
from the other two.)
Plato’s allegory in itself evokes
both images of freedom and restraint; of human beings bound by their
physical circumstances but nonetheless capable of obtaining some
degree of freedom. Readers of this blog will be familiar with my
assertion that human existence is characterized by both “affective
freedom” and “cognitive restraint.” We can imagine nearly
anything, despite being restrained by all the demands of physicality,
winsomely styled as the “Four F’s:” food (edible matter), flax
(clothing), flags (shelter) and frig (continuance of the species). As
I wrote previously, the imagination may or may not lead to useful
inventions that enhance the physical quality of life, but it should
always be seen as instrumental to all mental formulations.
Now, fantasy and science fiction pursue
distinct epistemological patterns, each in tune with the dominant
matrix in which they exist. In science fictional worlds, all wonders
are predicated on extensions of scientific principles, while in
fantasy, they arise from the concept of magic, which may range from
traditional “faerie” spellcraft to organized notions of
thaumaturgy. Within all of these worlds, the main characters are
generally in the position of the man freed from the chains of his
fellows and propelled into a greater cosmos.
In fantasy, a common trope is to show a
youth who lives in a bucolic existence, and who finds himself drawn
into events of cosmic importance, often involving the combat of good
and bad wizards and/or deities. Morris uses a rough variation of this
trope in his four fantasy-novels, particularly in THE SUNDERINGFLOOD, though he isn’t as successful in giving his protagonist a
grounding in the magical principles governing the world. Morris’s
spiritual disciple Tolkien is of course famous for having hurled
protagonists Bilbo and Frodo into the greater world of sorcery,
walking trees and enchanted rings. The bucolic world of the Shire,
from which both hobbits hail, does not as a whole wish to be tainted
with all of these momentous and enigmatic presences, but its
inhabitants are not really able to reject the magical cosmos in a
manner comparable to the chained people in the Cave. The very idea of
magic, as a force that transcends the limits of time and space,
stands aligned with the concept of affective freedom.
In contrast, the epistemology of the
Cave has a more ambivalent function in science fiction. For all the
differences between Verne and Wells, they have in common the fact
that many of their scientific seekers—the ones who part company
with the world of ordinary reality—meet catastrophic fates,
explicit with respect to Captain Nemo, implicit with respect to the
Time Traveler. Thus, science fiction can be somewhat aligned with the
concept of cognitive restraint, and not only because the forces of
science—even those of made-up, “impossible” science—are
supposed to cohere with the limits of time and space.
At the same time, science fiction shows
a greater emphasis upon following the destiny of the society than
that of the individual. Wells’ Eloi and Morlocks are bound by the
chains of a chimerical evolution much as are Plato’s cavepeople,
and they are doomed never to escape, existing to illustrate to the
protagonist the futility of life. Yet many of Wells’ disciples
altered the Platonic paradigm in order to promote a triumphalism of
science. It would probably be difficult to find a science fiction
author who advocated “truth” in a Platonic World of Forms, but
there are hundreds who see capital-S “Science” as such a truth.
Science fiction is riddled with protagonists who live in some
constricted society, whose people know nothing of scientific
principles, but who break free and bring the Good News of Science to
convert disbelievers. Such cosmic conversions underlie the enduring
appeal of a series like Isaac Asimov’s FOUNDATION trilogy, where
the advocates of a logical means of “reading history” are proven
to have superior insight over all competitors.
Not a few advocates of science fiction
have shown themselves to be hostile to the representations of
fantasy, confounding the fictional premises of fantasy-stories with
resentment of real-world religion and/or superstition. In so doing,
they validate only those products of the imagination which seem to
champion real-world science—even though, in point of fact,
constructs like Niven’s “Ringworld” and Blish’s “Cities in
Space” are not likelier to come into being than elves and orcs.
It’s a shame that science fiction enthusiasts have made this
conflation, for the activity of trying to fit the human imagination
into a box is not only fatuous, but futile beyond anyone’s attempt
to—imagine.
