All the interpretations advanced by these speculative theologians are even more deserving of rejection, with none accepted, since it is not known that any of them are true. If we have been commanded not to accept statements known to contain both truth and falsehood, then statements of this kind are even less deserving of acceptance. This is clear and evident for anyone whose purpose is to silence these people concerning such interpretations, prevent them from advancing them, and prevent their acceptance.

As for anyone whose purpose is to refute these interpretations and demonstrate their invalidity, he may say, in the seventh argument: These groups, all other Muslims, and all the people of the earth agree that some interpretations are false. They have not agreed that any of these interpretations are true, as explained above; and the truth upon which they agree is limited and well known. Each claims that reason necessitates his interpretation, while another claims that it is false and that the reasoning alleged to necessitate it is itself false, its falsity likewise being known through reason. They disagree about what they call the reason that must be followed.

There must therefore be a faculty of reason that distinguishes sound reasoning from unsound reasoning. Yet this faculty is of the same kind as their own rational faculties, so distinguishing what is sound in it from what is unsound
