Gustav Mahler

You don't need the iPhone: you have the most exquisite apparatus in the known universe sitting right in your head - the most complex organization of matter in the entire universe. And here are we, feeling a little depressed, feeling like we're not getting where we need to be, when really you might be exactly where you need to be.

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
