Challenge
help solve one of philosophy's greatest questions: is a room defined more by its corners or by its walls?
think of it anyway you want; what makes a room more defined as a room, the walls , or the corners?
walls
if you build a floor with four pillars on the corners, it's not really a room. if you build a floor with walls on each side that stop short right at the corners, it's still a room. not to mention circular rooms.
