I remember reading about two different types of goals for an intelligence. The gist was that the first type of goal is one that "just is" - it's an end goal for the system. There doesn't need to be any justification for wanting to achieve that goal, since wanting to do that is a fundamental purpose for that system. The second type of goal is a stepping stone, for lack of better words. Those aren't end goals in and of themselves, but they would help the system achieve its primary goals better.
I've forgotten the names for these types of goals and Googling didn't help me much. Is there a standard definition for these different types of goals?
