Clearly he optimized his brain for arts. Why would he be good at math?
In my experience the prevailing attitude of arts students towards science was that it was arcane, difficult and something reserved only for the smartest and most studious. Many science students, on the other hand, view liberal arts simply as a waste of time.
Neither attitude is particularly helpful.
It's only when I started to do technical writing that I let go of that attitude. It was quite humbling, to say the least.
I'm not ashamed of many of my faults, and I will gladly talk about them if they're contextually important, but I'm not proud of them.
