My rating: 4 of 5 stars
This is a stunning tour-de-force that I took on and was half way through before I realized HOW dated it was. I figured it was written in the mid-1960’s, given the level of knowledge the author possessed about the possibilities of the nature of alien life and the different species of astronomical objects he describes. I was staggered to find out it was published in 1937.
Does it read a little dated? Sure. The language is flowery and peppered with references to “Men” to describe every intelligent race. There is a narrative, but it is all told stream-of-consciousness without dialogue. “It was agreed among our party that we should continue further out into space.”
Reading this is a lot like looking at a painting by an abstract expressionist and shrugging it off until you realize it was painted when those artists were surrounded by Edwardian/Victorian stiffness as a style motif in design and popular art.
Olaf Stapledon was a true visionary–richly imaginative, but also writing a book decades beyond its time.
