There's a constant interplay between the hijinks and violence and cruelty that people can indulge in in copy, which drive the action of the plot, and the philosophical and moral issues raised by having arbitrarily good copies, each of whom feels, on creation, like the original. I think the hijinks are rather better done, probably because they're easier to compare with people's current behavior. The soul-wave science that allows the copying technology is a little too contrived for me to be swept into philosophizing that deduces things from it. The phil. isn't annoying.
