A Voyage to Arcturus
A Voyage to Arcturus is a novel by Scottish writer David Lindsay, first published in 1920. It combines fantasy, philosophy, and science fiction in an exploration of the nature of good and evil and their relationship with existence. It has been described by critic and philosopher Colin Wilson as the "greatest novel of the twentieth century" and was a central influence on C. S. Lewis's Space Trilogy.

The Necessity of Atheism
Plain speaking is necessary in any discussion of religion, for if the freethinker attacks the religious dogmas with hesitation, the orthodox believer assumes that it is with regret that the freethinker would remove the crutch that supports the orthodox. And all religious beliefs are "crutches" hindering the free locomotive efforts of an advancing humanity. There are no problems related to human progress and happiness in this age which any theology can solve, and which the teachings of freethought cannot do better and without the aid of encumbrances.

Astronomy: The Science of the Heavenly Bodies
The progress of astronomy from age to age has been far from uniform—rather by leaps and bounds: from the earliest epoch when man's planet earth was the center about which the stupendous cosmos wheeled, for whom it was created, and for whose edification it was maintained—down to the modern age whose discoveries have ascertained that even our stellar universe, the vast region of the solar domain, is but one of the thousands of island universes that tenant the inconceivable immensities of space...

Flying Saucers are Real
The Flying Saucers are Real is a book that investigates numerous encounters between USAF fighters, personnel, and other aircraft, and UFOs between 1947 and 1950. Keyhoe contended that the Air Force was actively investigating these cases of close encounter, with a policy of concealing their existence from the public until 1949. He stated that this policy was then replaced by one of cautious, progressive revelation. Keyhoe further stated that Earth had been visited by extraterrestrials for two centuries, with the frequency of these visits increasing sharply after the first atomic weapon test in 1945...

Raiders of the Universes
It was the 34th century and all five of the Federation of Planets around Sol were buzzing with their usual activity when the Raiders appeared. They were indeed Raiders of Universes because they had ravaged many systems before reaching Earth and showed no signs of slowing down in the least. Their weapons were invincible, their greed merciless and their natures completely alien. Indeed 'they' were from another dimension entirely. Eating up entire solar systems and planets, they slowed down just a bit when intelligent life was found on Earth...

Spacehounds of IPC
When the Inter-Planetary Corporation's (IPC) crack liner “IPV Arcturus” took off on a routine flight to Mars, it turned out to be the beginning of a unexpected and long voyage. There had been too many reports of errors in ship's flight positions from the Check Stations and brilliant physicist Dr. Percival (“Steve”) Stevens is aboard the Arcturus on a fact-finding mission to find out what's really happening, and hopefully save the honor of the brave pilots of the space-liner Arcturus from the desk-jockeys' in the Check Stations implications of imprecision - the nastiest insult you could cast at a ships pilot...
