Just as we know that when an artisan does a task he has only one intention, to do it to the very best of his ability, and that according to the greatness of his skill will be the accuracy of his work, and since we see that the world is created with the utmost accuracy, we know that God created it with the utmost wisdom. Just as the good artisan has but one intent, to do lovely and good work, and just as a good and wise potter* whose whole intention is to fashion very beautiful vessels; if one of them should come forth unattractive, crooked or imperfect, he will reject it and he will not include it with the beautiful vessels, but he will cast it aside or will break it—so, too, the Creator, blessed be He, had only one intent, to create in His world the good and the pious. And if there exists sinners, God rejects them, for they do not perfect the work of creation. Just as the wise artisan when he produces a beautiful piece of work boasts of it to all who see him, so does the Creator, blessed be He, glory in His pious ones, as it is said (Isaiah 44:23), “And he doth glorify Himself in Israel.” And it says further (ibid., 49:3), “Israel, in whom I will be glorified.” He vaunts Himself in His pious ones, for they testify to the perfection of His work and offer clear evidence to the righteousness of His deeds. As for the wicked, they are the opposite of which we have spoken. They place a blemish on His creation. They are a cause of the profanation of His glorious name. So that those who see them say that the work of the Creator, blessed be He, is not good, as it is said (Ezekiel 36:20), “And when they came unto the nations, whither they came, they profaned My holy name; in that men said of them: These are the people of the Lord, and are gone forth out of His land.”

The writer says: I have composed this work not to teach people what they do not know but to remind them of what they already know and which is very familiar to them. For you will find in most of my words only things which most people already know and do not have any doubt about.
