Unadvisable and stubborn
Together with pride there will naturally arise an unadvisable and unconvinced spirit. So that into whatever error or fault the enthusiast falls, there is small hope of his recovery. For reason will have little weight with him (as has been justly and frequently observed) who imagines he is led by a higher guide, by the immediate wisdom of God. And as he grows in pride, so he must grow in unadvisableness and in stubbornness also. He must be less and less capable of being convinced, less susceptible of persuasion, more and more attached to his own judgment and his own will, till he is altogether fixed and immovable.

31. Together with pride there will naturally arise an unadvisable and unconvincible spirit. So that into whatever error or fault the Enthusiast falls, there is small hope of his recovery. For reason will have little weight with him (as has been justly and frequently observed) who imagines he is led by an higher guide, by the immediate wisdom of God. And as he grows in pride, so he must grow in unadvisableness and in stubbornness also. He must be less and less capable of being convinced, less susceptible of persuasion; more and more attached to his own judgment and his own will, ’till he is altogether fixt and immovable.
