Iain M Banks' Second Culture Novel

I did not expect the Empire to be overthrown by the end of the novel but it was certainly ripe for revolution. The Emperor asserts that the most stable societies are those ruled by the strong and the ruthless but events prove that brutal dictatorship and enforced poverty generate so much general discontent and internal conflict that, after what may be a long period of apparent impregnability, they can be toppled quite quickly. A civilization in which every citizen genuinely has an equal stake in the status quo is another matter.

In the Empire, males impregnate apices who impregnate females. Apices are dominant. How does this work? We are familiar with the idea of an Emperor controlling both an army and a harem. If we imagine the Emperor not as a male with many wives or concubines and soldiers but as an apex with many husbands, wives and soldiers, then we will have translated familiar relationships into this fictitious scenario.

The Emperor addresses a Culture citizen disparagingly as a male but, since the Culture has only two sexes, its citizens have no choice but to be either male or female - although they can change. The Emperor's attitude is typical of his blinkered society. Another high-ranking apex remarks that, unfortunately, most of the unemployed are loafers. So that is the cause of social and economic problems, is it?

Apparently, at least one of Banks' sf novels is not set in the Culture history. "Other Books by the Same Author" pages should be divided into:

by Iain Banks;
the Culture sf series by Iain M Banks;
other sf by Iain M Banks.

From what I have seen so far, each Culture novel features different characters and a different aspect of society in a different period. This alone makes it unlike any other long futuristic sf series, to my knowledge.
