I always thought it was weird we tried to attach a fourth dimension to some things. It's not as if we could really comprehend them - can a square comprehend a cube? Can a circle comprehend a cylinder? I would guess 'no'. Which makes one wonder if three dimensions are required for life. Can a square be aware? Which, if there is an exponentially increasing complexity per dimension added, makes me wonder how incomprehensible a fourth dimension would be to us. Probably 'entirely'.
