“Assuredly we bring not innocence into the world, we bring impurity much rather: that which purifies us is trial, and trial is by what is contrary…. They are not skillful considerers of human things who imagine to remove sin by removing the matter of sin. For … it is a huge heap increasing under the very act of diminishing…. Good and evil we know in the field of this world grow up together almost inseparably…. It was from out of the rind of one apple tasted, that the knowledge of good and evil, as two twins cleaving together, leaped forth into this world. And perhaps this is that doom which Adam fell into of knowing good and evil, that is, of knowing good by evil.”
