All Human Creatures have the like Kinds and Sorts of Properties, Faculties, Respirations, and Perceptions; unless some Irregularities in the Production, occasion some Imperfections, or some Misfortunes, in some time of his Age: yet, no Man knows what another Man perceives, but by guess, or information of the Party: but, as I said, if they have have no Imperfections, all Human Creatures have like Properties, Faculties, and Perceptions: As for example, All Human Eyes may see one and the same Object alike; or hear the same Tune, or Sound; and so of the rest of the Senses. They have also the like Respirations, Digestions, Appetites; and the like may be said of all the Properties belonging to a Human Creature. But, as one Human Creature doth not know what another Human Creature knows, but by Confederacy; so, no Part of the Body, or Mind of a Man, knows each Part's perceptive knowledg, but by Confederacy: so that, there is as much Ignorance amongst the Parts of Nature, as Knowledg. But this is to be noted, That there are several manners and ways of Intelligences, not only between several sorts of Creatures, or amongst particulars of one sort of Creatures; but, amongst the several Parts of one and the same Creature. CHAP. X. Of the Irregularity of the Sensitive, and of the Rational Corporeal Motions. As I have often mentioned, and do here again repeat, That the Rational and Sensitive Parts of one Society, or Creature, do understand, as perceiving each other's Self-moving Parts; and the proof is, That, sometimes, the Human Sense is regular, and the Human Reason irregular; and sometimes the Reason regular, and the Sense irregular: but, in these differences, the Regular Parts endeavour to reform the Irregular; which causes, many times, repetitions of one and the same Actions, and Examinations; as, sometimes the Reason examines the Sense; and sometimes the Sense, the Reason: and sometimes the Sense and Reason do examine the Object; for, sometimes an Object will delude both the Sense and Reason; and sometimes the Sense and Reason are but partly mistaken: As for example, A fired end of a Stick, by a swift exterior Circular Motion, appears a Circle of fire, in which they are not deceived: for, by the Exterior Motion, the fired end is a Circle; but they are mistaken, to conceive the Exterior Figurative Action to be the proper natural Figure: but when one man mistakes another, that is some small Error, both of the Sense and Reason. Also, when one man cannot readily remember another man, with whom he had formerly been acquainted, it is an Error; and such small Errors, the Sense and Reason do soon rectifie: but in causes of high Irregularities, as in Madness, Sickness, and the like, there is a great Bustle amongst the Parts of a Human Creature; so as those Disturbances cause unnecessary Fears, Grief, Anger, and strange Imaginations. CHAP. XI. Of the Knowledg between the Sensitive Organs of a Human Creature.
