We're also the only species that can use abstraction to assign meaning to and relations between symbols in any way we choose. The humanities and the sciences are both extremely important to what makes us human, and saying that only one is 'what makes us us' will alienate those who are different from you.

That you are primarily driven by music and aesthetics, and others are primarily driven by science and technological creation, and most of us are driven by both in varying degrees - that is what makes us human.

I'm driven by all four. That's why I'm here! My point is that current culture as a whole allows for a large deficit in individuals' understanding the humanities. Especially around here, you will see comments suggesting that the humanities are not necessary, or are not viable career paths, etc.

It's not that one drive is more important than the other. It is that we as a contemporary society often treat arts that way. Your drive is vital too!
