I have just finished reading The Naked Sun by Isaac Asimov.
Elijah Baley is off on another murder investigation involving robots. This time he has to leave earth and head to the planet Solaris, where through generations of isolation and social conditioning human nature has been turned on its head (compared to earth). Where, on earth modern people live in dense population centers in close quarters to other people and never ever venture outside, most having never seen the sun or open sky, on Solaris, the population size is strictly regulated and people live on huge individual estates in isolation from others. Through use of 3D tele-viewing systems people never have to actually be in the physical presence of another and have grown to be terrified of actually seeing each other in person. Also, unlike the earth population which has shunned the use of robots in jobs involving humans, the Solarians each employ dozens of personal servant robots to meet their every need. Elijah is forced to reconcile these great differences as he struggles with his own debilitating discomfort of being outdoors, and the Solarians’ great anxiety of seeing him in person. This book is a both a murder mystery and sociological study of human nature (and nurture). I noticed that the Elijah Baley character seems to have matured some from the first book, Caves of Steel, and frequently seems to be more in charge of his behavior. After finishing this, I am jumping right in to the third book of the trilogy, Robots of Dawn.
