Dark Integers and Other Stories by Greg EganDark Integers and Other Stories by Greg EganDark Integers and Other Stories by Greg Egan

Though the count may not be high (five stories all told), Greg Egan’s Dark Integers and Other Stories packs a theoretical punch, quite literally. Novellas and novelettes only, the 2008 collection is filled with the author’s trademark hard science speculation. The selections were published between 1995 and 2007; one pair of stories is set within the same universe as his 2008 novel Incandescence, another pair within a near-future Earth setting, and the fifth is set on a water world. The quality of this collection is contentious, and certainly those who appreciate abstract theorizing will enjoy it the most.

The following is a brief summary of the five pieces:

“Luminous” (1995): In a shocking opening scene, a man awakes to find himself shackled to a bed and a woman operating on his arm trying to extract the data cache buried in his flesh. Containing invaluable and literally illogical formulas, he escapes to explain his story, and, once and for all, test the data lodged within. This correlates to something along the lines of:

Let me get this straight. What you’re talking about is taking ordinary arithmetic — no weird counter-intuitive axioms, just the stuff every ten-year-old knows is true — and proving that it’s inconsistent, in a finite number of steps?

The follow-through is more than even the man, let alone the corporation chasing him, thinks possible. An interesting story for anyone who likes pure mathematical paradoxes and the potential implications, but otherwise a bit blocky.

Riding the Crocodile (2005): A sketch leading up to Incandescence, this novella tells of a husband and wife who, after thousands of years alive, have decided to take on one last project before allowing themselves to die. Learning of a galactic system that has never been penetrated despite millions of attempts, the pair leave the Amalgam and set flight on their last adventure. But testing the hypothesis they propose puts their decision to the test in ways the reader cannot predict. Along with Oceanic, this is the strongest story in the collection. The title? Well, I missed something in the reading…

“Dark Integers” (2007): Picking up events ten years after “Luminous,” this novelette details new threats from illogical math. Bruno, Alison and Yuen think their secret has been safe, especially since the light-powered super-computer was decommissioned. But they quickly find themselves in a new predicament. Other researchers are driving toward similar theories and conclusions, which may lead to intergalactic war. Not truly answering the unanswered question which appeared at the conclusion of “Luminous,” Egan remains oblique, leaving matters open at the conclusion of “Dark Integers,” perhaps for a third story. Plot and theory are forced together into a marriage that works on a limited basis (I suppose like real life), and the story requires more abstract imagination for the concepts contained than is typical.

“Glory” (2007): Another story set in the Amalgam of Incandescence and Riding the Crocodile, this story opens on a sweet mix of pseudo-science pyrotechnics, which quickly escalates to post-human proportions as an anthropologist arrives on a distant planet to do research. Encountering local tensions, which are compounded by intergalactic hostilities, her job only becomes more difficult. A rather blunted story; this is not the most subtle of Egan’s work.

Oceanic (2008): Like Oracle, this is an Egan novella that pits science against religion. But unlike Oracle, which took real figures from history and set their ideologies up on opposing whiteboards with little story to move matters, Oceanic places story in the foreground. Egan’s mindset is on his sleeve, the story of Martin and his growing up on the planet is the most accessible of this collection, but it remains fully within the author’s moral purview. The climax exasperated me, since Egan continues to make no bones about his stance on religion.

Looking at the collection as a whole, Egan has desired touch points for each story, and he sticks to them. Character is a mere waypoint to speculation on mathematical theory and metaphysical quandaries, which confirms Egan’s reputation as one of the purest writers of hard science fiction today. It is thus no surprise that science is spun altruistically. The following passage from Riding the Crocodile (subtly) presents the mindset at work:

The meal they made was filling but bland. Leila resisted the urge to tweak her perceptions of it; she preferred to face the challenge of working out decent recipes, which would make a useful counterpoint to the more daunting task they’d come here to attempt. 

While certainly such people exist, the woman’s actions are presented through rose-tinted glasses. After all, what percentage of humanity prefers the high road to the low road? If Leila were the only character to display such an attitude, the shading could be forgiven. But the fact that all the characters behave and think in this fashion (save in Oceanic) skews the stories’ realism. A more daunting version of Arthur C. Clarke, Egan’s pro-science views come directly from character lips and story outcomes, his/their idealism taking precedence to individual humanity. The conclusion of Oceanic is, in particular, a statement in support of objectified knowledge, the implication being that all will benefit. While no word can be said against the optimism inherent to this view, a lack of empathy, or a disconnection to humanity at large, remains (i.e. those who lack the strength/willpower to take the high road and need to resort to other ways). Considering many of Egan’s other stories have very strong humanist ties, the stories here thus tend to be more idealistic, and must be approached as such.

In the end, Dark Integers and Other Stories is a good representation of Greg Egan’s longer short fiction. Hard science extrapolation on math, physics, and astronomy, along with the fundamental modes of thriller, bildungsroman, and planetary adventure, are used to tell highly abstract stories. In short, Dark Integers is an apt title. Oceanic is the most accessible piece, while “Luminous” and “Dark Integers” are the least, with Riding the Crocodile and “Glory” occupying territory somewhere in the middle. Likewise a mix of time, the publishing years range from 1995 (nearly the beginning of Egan’s writing career) to 2007 — a twelve year span in total.

Published in 2008. Greg Egan’s first new collection in a decade contains five stories, set in three worlds. In “Luminous,” two mathematicians searching for a flaw in the structure of arithmetic find themselves pitted against a ruthless arms manufacturer. In “Dark Integers,” their discovery has become even more dangerous, as they struggle to prevent a war between two worlds capable of mutual annihilation. “Riding the Crocodile” chronicles a couple’s epic endeavor a million years from now to bridge the divide between the meta-civilization known as the Amalgam and the reclusive Aloof. “Glory,” set in the same future, tells of two archaeologists striving to decipher the artifacts of an ancient civilization. In the Hugo-winning “Oceanic,” a boy is inducted into a religion that becomes the center of his life, but as an adult he must face evidence that casts a new light on his faith.
