The Devolutionist and the Emancipatrix

"The Devolutionist and the Emancipatrix" by Homer Eon Flint is a compilation of the two titular stories which have as a common theme, the topic of traveling to space using only one's mind and coming in contact with alien life forms. Written before man even went to the moon, these tales are a fascinating look at early science fiction and what society thought was in the future at the time of its writing.
