Finished A Time of Changes by Robert Silverberg. I enjoyed it - a thoughtful book.
This is my review:
Very much a product of its era, this novel comes from the middle of Silverberg's most productive period of quality, award-winning SF. Published in 1971, A Time of Changes won the 1972 Nebula Award for Best Novel, and was also nominated for both the Hugo and Locus Awards. On the world of Borthan it is forbidden by religious covenant to use personal pronouns, a moral crime known as 'self-baring'. Use of I or me is dreadfully rude and can lead to arrest. The Septarch's (monach's) younger brother, Kinnall Darival tells his tale by way of an autobiography.
As suggested, this is a product of its time - the novel explores the idea that psychotropic drugs can expand consciousness and be highly beneficial and it also contains a good deal of sexually-explicit scenarios. These are both hobby-horses of Silverberg, of course, so it's not surprising to come across such themes by him in a book from this era. Silverberg always manages to write about such themes from a very adult perspective, however, so they rarely seem at all gratuitous. But don't give it to your younger kids to read!
During his travels through the northern continent of Velada Borthan, the prince encounters a man from Earth, who introduces him to an illicit drug from the less-developed southern continent of Borthan. This drug opens up a connection between mutual takers of the substance. This connection reveals to Kinnall the benefits - love, respect and togetherness - that self-acknowledgement can bring.
The setting for the novel is unusual. It's certainly SF, as Kinnall meets an Earthman, Schweiz, and also discusses the historical settling of Borthan by those who came from Earth and spread across the galaxy. However, the culture seems quite primitive in most respects, and in tone and setting it bears resemblance to fantasy. In this respect, it shares some similarity to Silverberg's own Majipoor books. Overall, this is a well-written, thoughtful and successful book. Silverberg tackles some interesting themes, and his idea of a culture that bans consideration of 'self' is certainly thought-provoking.
