You have caused yourself endless trouble and misery for one reason. It wasn't enough for you to be happy that your mind was working as it should. You didn't think that was sufficient happiness.
Infinite are the troubles and miseries, that thou hast already been put to, by reason of this only, because that for all happiness it did not suffice thee, or, that thou didst not account it sufficient happiness, that thy understanding did operate according to its natural constitution.
