At the left side there is a hell where there are demons, as they ought to be called, who live from mere instinct, their rationality having been taken away. They are not so evil, but think when doing evil that they are doing good. So that place is for those who consider evils to be good and who, having been deprived of the ability to reason, abide there and think that they are ruling the universe. But they are then in a dream, as they themselves also said when they returned to themselves and their rationality was restored to them.
