Maimonides responds...And it is you who claims that God created everything. Are illnesses, disease, broken bones, starvation, birth defects, death and dying not evils that people endure through no fault of their own, but because they live in a universe created by God, as you profess to believe, a universe that would not exist unless it was not perfect?Are illnesses, disease, broken bones, starvation, death etc., good?
MEN frequently think that the evils in the world are more numerous than the good things, that just isn't the case. He who thinks that he can have flesh and bones without being subject to any external influence, or any of the accidents of matter, unconsciously wishes to reconcile two opposites, viz., to be at the same time subject and not subject to change. If man were never subject to change there could be no generation: there would be one single being, but no individuals forming a species. It would be in vain to expect to see living beings formed of the blood of menstruous women and the semen virile, who will not die, will never feel pain, or will move perpetually, or will shine like the sun. Whatever is formed of any matter receives the most perfect form possible in that species of matter: in each individual case the defects are in accordance with the defects of that individual matter. The best and most perfect being that can be formed of the blood and the semen is the species of man, for as far as man's nature is known, he is living, reasonable, and mortal. It is therefore impossible that man should be free from this species of evil. You will, nevertheless, find that the evils of the above kind which befall man are very few and rare.
