While we can't speak for the readers, we as researchers, writers, and editors have learned quite a bit. People are individuals, no matter which historical period they happen to live in. But if we generalize, it seems that the basic nature of people hasn't changed over time. During the entire period of recorded history, people have needed and wanted the same basic things that we need and want today. Non-material needs haven't changed much either.
People still desire acceptance, prestige, and other social values.
It doesn't seem like a mother's desire to care for her child has changed very much over the centuries. The desire for power and wealth also seems constant, although the way it is attained has changed dramatically over time and between cultures. And, of course, people have always had sensual desires. Quite a bit. Although the fundamental needs and desires of people may not have changed very much, their chances of attaining those desires has changed immensely, especially when we look at modern, developed societies.
