A volume of Robert Silverberg stories blew me away when I was young and eager for ideas based fiction. I think he might be the under-rated author of that era - talented with characters and narrative, yet provocative and thought provoking in terms of his conceptual exploration. However - decades (and probably puberty) sit in between me and my last reading of his work so this is probably an unreliable viewpoint.
