"Robot Dreams" is an anthology by Asimov and even if he was known by his robot stories, those that I considered the best in this book are about something else.
There are four short stories that seem the most representative: "Robot Dreams"; "The Last Question"; "The Ugly Little Robot" and "The Billiard Ball". Each of that quartet has a concept which gives a sense of greatness. Allow me to explain.
"Robot Dreams", the short story that gives the book a title, is about a robot that dreams a future not good to humans. The maximum expression of freedom to a being which supposedly can't have freedom.
"The Last Question" deals directly with the search for knowledge. During the entire span of existence of Humankind and beyond (through the Multivac) there is a haunting question "How can entropy of the universe can be decreased?". Amazing story and unexpected ending.
"The Ugly Little Robot" is about a Neandartal boy and a nurse. What a heart warming story...
"The Billiard Ball", a story of the friction of theorical science and engineering. The greatest mind of each side "fights" to be the best.
Of course the remaining stories are also good, some more than others. And all have something new to teach us.
Definitely a book to buy and keep.
Till next time,
