But let us keep in mind that another vision, in which the species' cataclysmic degeneration is not so profound - in other words, in which there would be some continuity in the current of civilizational transformations - would have made it impossible to write the book. For the ascent that follows exponentially from this premise would surpass the capacities of any artist's imagination. This means that even if the fate of humanity is not at all tragic, we are incapable of plausibly foreseeing - in the very distant future - different qualities of being, other than the tragic. [...] But the existence of future generations totally transformed from ours would remain an incomprehensible puzzle for us, even if we could express it.
It is a law of civilizational dynamics that instrumental phenomena grow at an exponential rate. Stapledon's vision owes its particular form and evenness to the fact that its author ignores this law. [...] Technological development is an independent variable primarily because its pace is a correlative of the amount of information already acquired, and the phenomenon of exponential growth issues from the cross-breeding of the elements of the mass of information. [...] His cautious pen never drove the narrative to `techno-orgiastic escalation,' and his societies are never threatened by hedonism. (pp. 285-7)
Lem's entire discussion is worth reading for its nuance as well as its
possible priority. His scathing criticism of the failure of imagination of
Western sf is now rather dated, happily, but still applies to most
`consumer fodder' science fiction. His own apparent lapse of imagination -
that proviso, `in the very distant future' - is compensated by his
insistence that *already* we have achieved most of the great technical
breakthroughs expected by Stapledon no sooner than millennia or even
millions of years hence. `[T]he moment of the chromosome structure's
discovery cannot be separated by "long millennia" from an increase in
knowledge that would permit, for example, the species to direct its
development' (p. 285). He even preempts Vinge's metaphor of an event
horizon of prediction: `[Stapledon] has invalidated the real factors of
exponential growth, which obstruct all long-range predictions; we can't see
anything from the present moment beyond the horizon of the 21st century'
(p. 287).
No less remarkably, perhaps, Lem made a cognitive leap seldom seen, I believe, outside these forums. There are reasons to doubt his conclusion, but it is an impressive leap of connective imagination:
`Predictions beyond 80 or 100 years inevitably fail. Beyond that range lies
the impenetrable darkness of the future, and above it, a single definite
sign indecipherable, but impinging on us all the more: the Silence of the
Universe. The universe has not yielded to the radiance of cilivizations; it
does not scintillate with brilliant astro-technical works - although that
is how it should be, if the law of psychozoic beings were an aspect of the
exponential ortho-evolution of instrumentality in cosmic dimension.' (p. 288)
Nice going, Dr Lem!
