...are precisely what is necessary... For the Supreme Wisdom undoubtedly calculated exactly everything that was necessary, neither more nor less. For with just one degree higher or one degree lower, things would immediately be different. For example, if man were one level higher than his actual level, he would be like the angels, with no evil inclination, whereas if he were one level lower, he would be like an animal.
