<Li> We judge that, in the prosecution of these and all such witchcrafts, there is need of a very critical and exquisite caution, lest by too much credulity for things received only upon the Devil's authority, there be a door opened for a long train of miserable consequences, and Satan get an advantage over us; for we should not be ignorant of his devices . </Li> <Li> As in complaints upon witchcrafts, there may be matters of inquiry which do not amount unto matters of presumption, and there may be matters of presumption which yet may not be matters of conviction, so it is necessary, that all proceedings thereabout be managed with an exceeding tenderness towards those that may be complained of, especially if they have been persons formerly of an unblemished reputation . </Li> <Li> When the first inquiry is made into the circumstances of such as may lie under the just suspicion of witchcrafts, we could wish that there may be admitted as little as is possible of such noise, company and openness as may too hastily expose them that are examined, and that there may no thing be used as a test for the trial of the suspected, the lawfulness whereof may be doubted among the people of God; but that the directions given by such judicious writers as Perkins and Bernard (be consulted in such a case). </Li> <Li> Presumptions whereupon persons may be committed, and, much more, convictions whereupon persons may be condemned as guilty of witchcrafts, ought certainly to be more considerable than barely the accused person's being represented by a specter unto the afflicted; inasmuch as it is an undoubted and notorious thing, that a demon may, by God's permission, appear, even to ill purposes, in the shape of an innocent, yea, and a virtuous man . Nor can we esteem alterations made in the sufferers, by a look or touch of the accused, to be an infallible evidence of guilt, but frequently liable to be abused by the Devil's legerdemains . </Li>
