 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 the nerves, and other strings and membranes of the body, continued inwards to the brain and hearth, causeth there a resistance, or counter-pressure, or endeavour of the earth 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, as to the eye, in a light, or colour figured; to the ear, in a sound…if those colours and sounds were in the bodies, or objects that cause them, they could not severed by 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.
