When you find yourself fixated on an idea in philosophy--a better definition of justice, an error in Hume's logic, or the result of some paradigm shift between one philosophical era and another--do you become a moron? It would be pretentious to call myself a philosopher, but I spend quite a bit of time reading and trying to figure out whether or not my favorite philosophers made as much sense as they seem to at first glance; the more headway I make, the more often I stare blankly at the microwave trying to figure out what buttons to push to heat up my coffee. Do real philosophers go through this? Or do you function better in the world when you have been wrestling with brain puzzles?
