a general Irregular Commotion or Action, all the Sensitive Parts of the Body of a man, agree to move with an extraordinary force, after an unusual manner; provided it be not different from the property and nature of their Compositions; that is, not different from the Property and Nature of a Man. But this is likewise to be noted, That in a general Agreement, man may have other Properties, than when the whole Body is governed by Parts, as it is usual when the Body is Regular, and that every Part moves in his proper Sphere, as I may say, (for example) the Head, Heart, Lungs, Stomack, Liver, and so the rest, where each Part doth move in several sorts of Actions. The like may also may be said of the Parts of the Leggs and Hands, which are different sorts of Actions; yet all move to the use and benefit of the whole Body: but, if the Corporeal motions in the Hands, and so in the Leggs, be irregular, they will not help the rest of the Parts; and so, in short, the same happens in all the Parts of the Body, whereof some Parts may be Regular, and others Irregular; and sometimes all may be Irregular. But, to conclude this Chapter, the Body may have unusual Force and Properties; as when a man says, He was carried and flung into a Ditch, or some place distant; and that he was pinch't, and did see strange sights, heard strange sounds, smelt strange scents; all which may very well be caused by the Irregular motions, either by a general Irregularity, or by some particular Irregularity; and the truth is, The particular Corporeal motions, know not the power of the general, until they unite by a general Agreement; and sometimes there may be such Commotions in the Body of a Man, as in a Common-wealth, where many times there is a general Uproar and Confusion, and none know the Cause, or who began it. But this is to be noted, That if the Sensitive motions begin the Disorder, then they cause the Rational to be so disordered, as they can neither advise wisely, or direct orderly, or perswade effectually.
