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.

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...

This report from 1956 takes us inside these initial investigations, separates fact from fiction, and gives insight into who, when, where, and how sightings were reported and researched in open-minded fashion (for which Ruppelt was renowned), rather than in the typical hushed and secretive (and censored) manner most often associated with government and military reports which are released to the public...

"Histories are more full of examples of the fidelity of dogs than of friends."The character, sensibilities, and intellectual faculties of animals have always been a favourite study, and they are, perhaps, more strongly developed in the dog than in any other quadruped, from the circumstance of his being the constant companion of man.
