R. Daneel Olivaw

I'm rereading _The Caves of Steel_ for the first time in nearly
eight years. Coming at it (relatively) fresh, I'm picking up on
things that I'd previously overlooked.

The one that brought this to mind was the fact that R. Daneel
was "[...] constructed for the purpose of cerebroanalysis."

This line lays the groundwork for what Asimov would do over
thirty years later in _The Robots of Dawn_. I absolutely do not
believe that this was devious advance planning, but it did
turn out rather handy.
