The fact that the evil ones, as long as they live, can be corrected from their errors does not prohibit that they may be justly executed, for the danger which threatens from their way of life is greater and more certain than the good which may be expected from their improvement.

Behold our refutation of the error. It is not based on documents of faith, but on the reasons and statements of the philosophers themselves. If then anyone there be who, boastfully taking pride in his supposed wisdom, wishes to challenge what we have written, let him not do it in some corner nor before children who are powerless to decide on such difficult matters. Let him reply openly if he dare. He shall find me there confronting him, and not only my negligible self, but many another whose study is truth.

Gods are called many by the error of some who worshipped many deities, thinking as they did the planets and other stars were gods, and also the separate parts of the world.

Any error about creation also leads to an error about God.

Mistakes are made on two counts: an argument is either based on error or incorrectly developed.
