Well, if you look closely, Reason may be large, but it hasn’t got much and seems rather dry. If you’ll note, Bureaucracy is there with Law. That takes up alot of empty space ;^)
Wisdom, on the other hand, is smaller, but full of interesting places, with lots of lakes, and just generally looks like a better land mass to me. Wisdom also has Freedom & Justice, Faith and Eros (Love) (although be careful since Eros is close to Lust). One could definitely spend a long time reading that map, and debating the placement of various things.
Wisdom or Reason look like better places to live, but I think I’d rather vacation in Hedonism. :-)
