Philip K Dick is fantastic at weaving stories about what is reality, or what is living and what is not. These stories hit so many notes. Autofac - World is ended for humans (or is it?), and now the factories battle for resources. (Repeating why we go to war?) Electric Ant - Wow, are any of us really alive? Or just some experiment? Who knows! He will blow your mind.
The previous individual's review is horribly inaccurate. True, it's written long ago, but the ideas behind these stories each could make an episode of OUTER LIMITS, or even a Blockbuster Movie. Listen to the stories with an open mind, and understand what his reasons for writing them were.
I actually used Autofac as a 1st story read for my High School class.
