A Columbus of Space

A classic science fiction novel. The basic story is set in the nineteenth century, where a man asks his friends if they want to see something he has been working on and they all end up taking a trip to Venus, where there are different societies depending on if you live on the sun side or the no-sun side of the planet, where all you need as a human to survive is a fur coat and a pistol, and the people have tapped into the higher powers of the brain for communication.
