After reading seven of the (so far) fourteen “Man-Kzin Wars,” I figured it was time for a break, so in a serendipitous event I ran across this treasure in a used bookstore. It consists of three previously published works, which apparently led up to the events of “Ringworld” and the “Man-Kzin Wars.”
“World of Ptavvs” and “A Gift from Earth” are novels, while “Tales from Known Space” is a collection of short and long stories; this last is put in what Mr. Niven sees as “chronological order” and gives a table of happenings in Known Space, with dates and references to the stories and the novels. I had seen this device in Robert A. Heinlein’s “Methuselah’s Children,” “The Past Through Tomorrow” and “Time Enough for Love,” and had referred to it numerous times when I read these works, very helpful.
The book starts off with several shorter works concerned with planetary exploration in our own Solar System, starting with Mercury. Several of the stories relate specifically to colonization on Mars, and Mr. Niven well describes the hazards and unforgiving atmosphere of the Martian landscape, as well as the psychological toll on humans who brave such a frontier and tragic results thereof. Another theme throughout these stories is extension of life through transplant technology, which makes rapid advances and extends life, but not without consequences. More about that below.
Yet another theme is the relationship (mostly tense) between Earthians, referred to as “flatlanders,” and “Belters,” colonizers of the Asteroid Belt, frontiersmen of a sort, with independent and antiauthoritarian attitudes. These figures also turn up in the “Ringworld” and “Man-Kzin Wars” books. Relatedly, one such unique asteroid, dubbed the “Confinement Asteroid,” is described as – well, let me quote here:
“Early explorers had run across a roughly cylindrical block of solid nickel-iron two miles long by a mile thick, orbiting not far from Ceres. They had marked its path and dubbed is S-2376. Those who came sixty years ago were workmen with a plan. They drilled a hole down the asteroid’s axis, filled it with plastic bags of water, and closed both ends. Solid fuel jets spun S-2376 on its axis. As it spun, solar mirrors bathed in light, slowly melted it from the surface to the center. When the water finished exploding, and the rock had cooled, the workmen had a cylindrical nickel-iron bubble twelve miles long by six in diameter…They rotated the bubble to provide a half gee of gravity, filled it with air and with tons of expensive water, covered the interior with a mixture of pulverized stony meteorite material and garbage seeded with select bacteria. A fusion tube was run down the axis, three miles up from everywhere; a very special fusion tube, made permeable to certain wavelengths of light. A gentle bulge in the middle created the wedding-ring lake which now girdles the little inside-out world. Sun-shades a mile across were set to guard the poles from light so that snow could condense there, fall of its own weight, melt and run in rivers to the lake.”
This development was the final one in ensuring independence from Earth, largely because it made childbirth possible (Niven theorizes that childbirth is impossible in space; I’d wonder what NASA would say about that now). This certainly presages the description of the Ringworld in many important dimensions, and I felt it was quite cleverly done. I also saw similarities with Arthur C. Clarke’s “Rendezvous with Rama” (Read the first one, skip the next three).
“The World of Ptavvs” takes us a bit afield, with the discovery in contemporary times of a “statue” at the bottom of the ocean which is several million years old; turns out that it’s a thrintun, a race that has extremely well-developed psi powers, with which he/she uses to control slaves. A Ptavv is a thrint that hasn’t fully developed “The Power;” such thrints are basically treated like inferior beings, little higher than slaves. Well, this thrint had crash-landed his spacecraft and had gone into suspended animation for all this time. Of course we have those wacky scientists that wish to revive and study this well-preserved specimen, with quite disastrous consequences, for you see, this here thrint looks upon humans as ptavvs and therefore subject to – well, subjugation. So our friend (Kzanol’s his name) manages to escape, with the remainder of the book concerned with the attempts to find and recapture him. Fun times.
“A Gift from Earth” is related to a colonized planet called Mount Lookitthat. This is one of several planets colonized by about 2100, including We Made It, Jinx, and Wunderland, all of which are referred to in the “Ringworld” and “Man Kzin Wars” books. The only habitable places on Mt. Lookitthat are two large plateaus which are situated above a poisonous-fog layer. The colonists had been brought in large ships which continue to be used as sources of electricity and other power. Occasionally, a smaller, unmanned ship arrives with supplies, or advances in technology that will help the colonists. In that context, there are, of course, administrative/police personnel, which are referred to collectively as “Crew,” as they had been the crew of the large transport ships. The main way to ensure continued and long life for the inhabitants is by transplant technology, and those organs are provided by euthanizing criminals and harvesting said organs. There is, not surprisingly, a revolutionary band from among the “not-Crew,” which has been in existence, protesting such a fate for any criminal, and wishing to destroy the “Hospital,” a euphemism for the euthanizing center/organ bank. With this background, one of the small ships arrives containing – well, let’s say, something that could well alter the balance of power. This is a fascinating tale, not only of projected technology but also of social and moral issues related to it.
These are, to my mind, the main ideas of this book and Mr. Niven’s vision of our future. There are quite a number of smaller notions and many more detailed aspects of all these stories, which makes for very fascinating reading. I wish I had read all these before reading “Ringworld,” as that would have given me a comprehensive background for it. And, to tell the truth, these earlier works are better ones than the “Ringworld” books (see my reviews). Five stars!
