I am trying to determine an overall theme to connect the stories within "The Illustrated Man", but have only gotten so far as that it relates to human nature and, possibly, its relation to technology. I am also exploring Bradbury's strong literary skill, but am lost in this as well.There's imagery, of course, but I wonder if the rockets and the image of the sun are meant to be motifs.

Could anyone give me their opinion on overall theme and literary skill?
