H. G. Wells 
Mankind in the Making 

One of the primary motivations behind H. G. Wells most popular science fiction works was his exploration of the factors that could help or harm society. As a result, many of his novels and short stories explored utopian or dystopian worlds. In Mankind in the Making, he tackles the same topic from a nonfiction perspective, ruminating on the variables that serve optimal human development from conception to adulthood.
