CHAPTER I.—OF SENSE.—‘Concerning the thoughts of man, I will consider them, first singly, and afterwards in train, or dependence upon one another. Singly, they are every one a representation or appearance of some quality or other accident of a body without us; which is commonly called an _object_: Which object worketh on the eyes, ears, and other parts of man’s body; and by diversity of working, produceth diversity of appearances. ‘The Original of them all is that which we call SENSE: For there is no conception in a man’s mind which hath not at first, totally or by parts, been begotten upon the organs of sense. The rest are derived from that original. ‘The cause of sense is the external body or object which presseth the organ proper to each sense, either immediately as in the taste and touch, or mediately as in seeing, hearing, and smelling: which pressure by the mediation of nerves, and other strings and membranes of the body, continued inwards to the Brain and Heart, causeth there a resistance or counter-pressure, or endeavour of the heart to deliver itself: which endeavour, because _outward_, seemeth to be some matter without. And this seeming or fancy is that which men call sense: and consisteth to the eye, in a light or colour figured; to the ear, in a sound; to the nostril, in an odour; to the tongue and palate, in a savour, and to the rest of the body in heat, cold, hardness, softness, and such other qualities, as we discern by feeling. All which qualities called _sensible_ are in the object that causeth them but so many several motions of the matter by which it presseth our organs diversely. Neither in us that are pressed are they any thing else but divers motions; for motion produceth nothing but motion. But their appearance to us is fancy, the same waking as dreaming. And as pressing, rubbing, or striking the eye maketh us fancy a light, and pressing the ear produceth a din, so do the bodies also we see or hear produce the same by their strong, though unobserved action. For if those colours and sounds were in the bodies or objects that cause them, they could not be severed from them, as by glasses and in echoes by reflection we see they are: where we know the thing we see is in one place, the appearance in another, and though at some certain distance, the real and very object seems invested with the fancy it begets in us; yet still the object is one thing, the image or fancy is another. So that sense in all cases is nothing else but original fancy; caused, as I have said, by the pressure, that is, by the motion of external things upon our eyes, ears, and other organs thereunto ordained.
