I'm with Aristotle - "all men desire happiness". Nothing else is desired for its own sake, but always for the sake of "happiness". That said, I don't think that knowing that happiness is what we desire tells us very much. We need to go deeper or wider and learn more about the world and ourselves in order to answer the question "in what does our happiness consist". In other words, we need to examine what we have received (since the world and even our selves are experienced as a gift). Which, coincidentally, is one of the ways that we can intuit that someone gave us what we have - because the principle of sufficient reason says that "an effect must have a cause sufficient to explain it" and we are an effect. "If I am a gift receiver, there must be a gift giver, and as their gift is great they must be greater still to be able to give so much away".
